Article 11.(Agricultural or forestry) tractor means any motor vehicle fitted with wheels or endless tracks and having at least two axles, the main function of which lies in its tractive power and which is specially designed to, push, carry or power certain tools, machinery or trailers intended for agricultural or forestry use. It may be equipped to carry a load and passengers.2.This Directive shall apply only to tractors defined in paragraph 1 which are fitted with pneumatic tyres and which have two axles and a maximum design speed of between 6 and 40 km/h.

Article 21.No Member State may refuse EEC type-approval or national type-approval of a tractor or refuse its registration or prohibit the sale, entry into service or use of a tractor or grounds relating to:dimensions and towable masses,speed governors and protection of drive components, projections and wheels,windscreens and other glazing,mechanical couplings between tractor and towed vehicle, including the vertical load on the coupling point,location and method of affixing statutory plates and inscriptions to the body of the tractor,brake control for towed vehicles,where these comply with the requirements of the Annexes relating thereto and where the windscreens and other glass panes or the mechanical couplings bear an EEC component type-approval mark.2.By way of derogation from the provisions of paragraph 1 relating to use of the tractor, Member States may, for reasons concerning towable mass(es), continue to apply their national provisions reflecting in particular the special requirements relating to the nature of the land relief on their territory, within the limits of the towable masses listed in section 2.2 of Annex I in so far as this does not involve alterations to the tractor or a further supplementary national type-approval.

Article 31.Each Member State shall grant EEC component type-approval for any type of windscreen or other glass-pane and/or of mechanical coupling which satisfies the construction and testing requirements laid down in Annexes III and/or IV.2.The Member State which has granted EEC component type-approval shall take the measures required in order to verify, in so far as is necessary and if need be in cooperation with the competent authorities in the other Member States, that production models conform to the approved type. Such verification shall be limited to spot checks.

Article 4Member States shall, for each type of windscreen or other glass pane or of mechanical coupling which they approve pursuant to Article 3, issue to the manufacturer of the tractor, windscreen or mechanical coupling or to his authorized representative, an EEC component type-approval mark conforming to the models shown in Annex III or IV.Member States shall take all appropriate measures to prevent the use of marks liable to create confusion between the type of equipment which has been granted EEC component type-approval pursuant to Article 3 and equipment of other types.

Article 51.No Member State may prohibit the placing on the market of windscreens and other glass panes or mechanical couplings on grounds relating to their construction if they bear the EEC component type-approval mark.2.Nevertheless a Member State may prohibit the placing on the market of windscreens or mechanical couplings bearing the EEC component type-approval mark which do not conform to the approved type.That State shall forthwith inform the other Member States and the Commission of the measures taken, specifying the reasons for its decision.

Article 6The competent authorities of each Member State shall within one month send to the competent authorities of the other Member States a copy of the component type-approval certificates, examples of which are given in Annex III or IV, completed for each type of windscreen or mechanical coupling which they approve or refuse to approve.

Article 71.If the Member State which has granted EEC component type-approval finds that a number of windscreens or mechanical couplings bearing the same EEC component type-approval mark do not conform to the type which it has approved, it shall take the necessary measures to ensure that production models conform to the approved type. The competent authorities of that State shall advise those of the other Member States of the measures taken, which may, if necessary, where there is serious and repeated failure to conform, extend to withdrawal of EEC component type-approval. The said authorities shall take the same measures if they are informed by the competent authorities of another Member State of such failure to conform.2.The competent authorities of the Member States shall inform each other within one month of any withdrawal of EEC component type-approval and of the reasons for such a measure.

Article 8Any decision taken pursuant to the provisions adopted in implementation of this Directive to refuse or withdraw EEC component type-approval for a windscreen or mechanical coupling or to prohibit their placing on the market or use, shall set out in detail the reasons on which it is based. Such decisions shall be notified to the party concerned, who shall at the same time be informed of the remedies available to him under the laws in force in the Member States and of the time limits allowed for the exercise of such remedies.

Article 9Any amendments necessary to adapt the requirements of the Annexes to technical progress shall be adopted in accordance with the procedure laid down in Article 13 of Directive 74/150/EEC.

Article 101.Member States shall bring into force the provisions necessary in order to comply with this Directive by 31 December 1989. They shall forthwith inform the Commission thereof.2.Member States shall notify to the Commission the texts of the main provisions of national law which they adopt in the field covered by this Directive.

Article 11This Directive is addressed to the Member States.

ANNEX IDIMENSIONS AND TOWABLE MASSES1.DEFINITIONS1.1."Length" means:the length of the tractor measured between the vertical planes at right angles to the longitudinal axis of the tractor and passing the outermost points thereof, but excluding:all mirrors,all starting handles,all front or lateral position (side) lamps.1.2."Width" means:the width of the tractor measured between the vertical planes parallel to the longitudinal axis of the tractor and passing through the outermost points thereof, but excluding:any mirrors,any direction indicators,any front, lateral or rear position (side) lamps; any parking lamps,any distortion of the tyres caused by the weight of the tractor,any folding components such as lift-up footrests and flexible mud-flaps.1.3."Height" means:the vertical distance between the ground and the point on the tractor the greatest distance from the ground, excluding the aerial. When this height is determined, the tractor must be:fitted with new tyres having the greatest rolling radius specified by their manufacturer.1.4."Permissible towable mass"means the mass which a type of tractor may tow. It may, for example, consist of one or more trailers towed or agricultural or forestry implements. A distinction is drawn between the technically permissible towable mass stated by the manufacturer and the authorized towable mass as laid down in section 2.2 below.1.5."Towing device"means a component on the tractor designed to provide a mechanical link between a tractor and towed vehicle.1.6."Unladen mass of tractor in running order (Mt)"means the mass defined in point 2.4 of Annex I to Directive 74/150/EEC.1.7.Technically permissable towable mass(es):unbraked towable mass,independently braked towable mass (as defined in point 1.12 of Annex I to Council Directive 76/432/EECOJ No L 122, 8. 5. 1976, p. 1.,inertia braked towable mass (as defined in point 1.14 of Annex I to Directive 76/432/EEC),towable mass fitted with hydraulic or pneumatic braking: such braking may be of the continuous, semi-continuous or independent power-operated type as defined in points 1.9, 1.10 and 1.11, respectively, of Annex I to Directive 76/432/EEC.2.REQUIREMENTS2.1.DimensionsThe maximum dimensions of a tractor are as follows:2.1.1.length12 m;2.1.2.width2,55 m (ignoring any bulging of the part of the tyres that is in contact with the ground);2.1.3.height4 m.2.1.4.The measurements intended to check these dimensions are carried out as follows:with the tractor unladen and in running order as indicated in point 1.6,on a flat horizontal surface,with the tractor stationary and the engine switched off,with the new tyres at the normal pressure recommended by the manufacturer,with doors and windows closed,with the steering wheel in the straight-ahead position,without any agricultural or forestry implement attached to the tractor.2.2Permissible towable mass2.2.1.The permissible towable mass must not exceed:2.2.1.1.the technically permissible towable mass as defined in point 1.7, recommended by the tractor manufacturer;2.2.1.2.the towable mass laid down for towing device pursuant to EEC component-type approval.2.2.2.Where a Member State applies Article 2 (2), towable mass(es) must be specified on the tractor's registration certificate.ANNEX IISPEED GOVERNOR AND PROTECTION OF DRIVE COMPONENTS, PROJECTIONS AND WHEELS1.SPEED GOVERNOR1.1.If a speed governor is fitted as standard by the manufacturer, it must be installed and designed in such a way that the tractor complies with Directive 74/152/EECOJ No L 84, 28. 3. 1974, p. 33. on maximum design speed.2.PROTECTION OF DRIVE COMPONENTS, PROJECTIONS AND WHEELS2.1.General2.1.1.Drive components, projections and wheels on tractors must be designed, fitted and protected in such a way as to prevent accidents to persons under normal conditions of use.2.1.2.The requirements of point 2.1.1 are regarded as being fulfilled if the requirements set out in section 2.3 have been complied with. Solutions other than those described in section 2.3 are authorized if the manufacturer provides proof that they are at least equivalent to the requirements of section 2.3.2.1.3.Protective devices must be firmly attached to the tractor. "Firmly attached" means that removal of such devices should be possible only with the aid of tools.2.1.4.Cowls, lids and hoods, which could cause injury if they are slammed shut, must be made in such a way as to preclude their shutting accidentally (e.g. by means of safety devices or suitable mounting or design).2.1.5.A single protective device may protect a number of dangerous points. However, if adjustment, maintenance or interference suppression devices — which can be actuated only when the engine is running — are fitted beneath a single protective device, then further protective devices must be fitted.2.1.6.Securing devices (e.g. spring clips or flaps)to secure quick-release mounting components (e.g. socket pins),and such components ofprotective devices which open without the aid of tools (e.g. engine cowl)must be firmly attached either to the tractor mounting or to the protective device.2.2.Definitions2.2.1."Protective device" means a device intended to protect dangerous parts. Within the meaning of this Directive, protective devices include shields, covers or guards.2.2.1.1."Shield" means a protective device located immediately in front of a dangerous part and which, either on its own or with other parts of the machine, protects on all sides against contact with the dangerous part.2.2.1.2."Hood or cowl" means a protective device located in front of the dangerous part and which protects against contact with the dangerous part on the covered side.2.2.1.3."Guard" means a protective device which, by means of a rail, grill or similar device provides the necessary safety distance preventing contact with the dangerous part.2.2.2."Dangerous part" means any point which, owing to the arrangements or design of the fixed or movable part of a tractor, involves a risk of injury. The dangerous parts are, in particular, pinching, shearing, cutting, piercing, penetrating, snatching, entry and attack points.2.2.2.1."Pinching point" means any dangerous point where parts move in relation to each other or to fixed parts in such a way as may cause persons or certain parts of their bodies to be pinched.2.2.2.2."Shear point" means any dangerous point where parts move along each other or along other parts in such a way as may cause persons or certain parts of their bodies to be pinched or shorn.2.2.2.3."Cutting, piercing or penetration point" means any dangerous point where parts, either moving or fixed, sharp edged, pointed or blunt may injure persons or certain parts of their bodies.2.2.2.4."Snatching point" means any dangerous point where sharp-edged projections, teeth, pins, screws and bolts, grease nipples, shafts, shaft ends and other parts move in such a way that persons, certain parts of their bodies or clothing may be snatched and pulled along.2.2.2.5."Entry or attack point" means any dangerous point whose parts, by moving, narrow an aperture in which persons, certain parts of their bodies or clothes may be caught.2.2.3."Reach" means the maximum distance which can be reached by persons or certain parts of their bodies upwards, downwards, inwards, above, around or across without the aid of any object (Figure 1).2.2.4."Safety distance" means the distance corresponding to the reach or to the body dimension plus a safety margin (Figure 1).2.2.5."Control" means any device whose direct actuation enables the state or operation of the tractor or of any equipment linked to it to be altered.2.2.6."Normal operation" means the use of the tractor for the purpose intended by the manufacturer and by an operator familiar with the tractor characteristics and complying with the information for operation, service and safe practices, as specified by the manufacturer in the operator’s manual and by signs on the tractor.2.2.7."Inadvertent contact" means unplanned contact between a person and a hazard location resulting from the person’s action during normal operation and service of the tractor.2.3.Safety distances for avoiding contact with dangerous parts2.3.1.The safety distance is measured from those points which may be reached to actuate, service and inspect the tractor, and also from ground level. "Servicing and inspecting the tractor" solely means work normally carried out by the driver himself in accordance with the instructions for use. In determining the safety distances the basic principle is that the tractor is in the state for which it has been designed and that no means has been used in order to reach the dangerous part.Safety distances are set out in points 2.3.2.1 to 2.3.2.5. In certain specific areas or for certain specific component parts an appropriate safety level is provided if the tractor corresponds to the requirements set out in points 2.3.2.6 to 2.3.2.14.2.3.2.Protection of dangerous pointsUpwardsThe upward safety margin is 2500 mm (see Figure 1) in the case of persons standing upright. 01989L0173-20060327_en_img_1

2.3.2.2.Downwards, aboveThe safety margin for reaching above a barrier is:afrom ground level up to the dangerous point;bheight of barrier or protective device;chorizontal distance between dangerous point and barrier (see Figure 2). 01989L0173-20060327_en_img_2

When reaching both downwards and above the safety distances set out in Table 1 must be maintained.TABLE 1

2.3.2.3.Reach aroundThe safety margin shown in Table 2 below must, at the minimum, be maintained if the part of the body concerned is not to reach a dangerous point. In applying the safety margin it is assumed that the main body joint concerned is pushed firmly against the edge of the protective device. The safety margins are not considered to have been maintained until one is satisfied that part of the body may quite definitely not advance or penetrate further.TABLE 2 01989L0173-20060327_en_img_3

2.3.2.4.Penetration and reach acrossIf penetration is possible into or across openings and up to dangerous parts, the minimum safety distances set out in Tables 3 and 4 must be maintained.Parts which move in relation to one another or moving parts set alongside fixed parts are not regarded as risk factors provided they are no more than 8 mm apart.TABLE 3Safety distances for elongated and parallel openingsa is the smaller dimension of the aperture.b is the safety distance from danger point 01989L0173-20060327_en_img_5

TABLE 4Safety distances for square or circular aperturesa is the aperture/diameter or length of side.b is the safety distance from danger point. 01989L0173-20060327_en_img_6

2.3.2.5.Safety distances at pinching pointsA pinching point is not considered dangerous for the part of the body shown if the safety distances are not less than those set out in Table 5, and if it is ensured that the adjacent, wider part of the body cannot be introduced.TABLE 5 01989L0173-20060327_en_img_7

2.3.2.6.ControlsThe gap between two pedals and the holes through which controls pass are not regarded as being pinching or shearing points.2.3.2.7.Rear three-point coupling2.3.2.7.1.Behind a plane passing through the median plane of the pivot points of the lifting rods in a three-point coupling system a minimum safety margin of 25 mm must be maintained between the moving parts for each point or of the lifting device's travel — but not for the extreme upper and lower positions 0,1 n, together with a distance of 25 mm or a minimum angle of 30o for the parts in shear which cause a change in angularity (see Figure 3). Travel n′, reduced by 0,1 n at both its upper and lower ends is defined as follows (see Figure 4).Where the lower links are directly activated by the lifting mechanism, the reference plane is determined by the median transverse vertifical plane of those links: 01989L0173-20060327_en_img_8

Legend:A = Lift armB = Lower linkC = Lift rodD = Tractor chassisE = Plane passing through the axes of the lift rod pivot pointsF = Clearance envelope 01989L0173-20060327_en_img_10

2.3.2.7.2.For travel n of the hydraulic lifting unit, lower position A of the coupling point of the lower link is limited by dimension "14" in accordance with ISO Standard 730, Part 1, while upper position B is limited by the maximum hydraulic travel. Travel n′ corresponds to travel n reduced upwards and downwards by 0,1 n, and constitutes the vertical distance between A′ and B′.2.3.2.7.3.Moreover, within travel n′ a minimum safety margin of 25 mm in relation to the adjacent parts must be maintained around the profile of the lifting rods.2.3.2.7.4.If, in the case of a three-point coupling, coupling devices are used which do not require the presence of an operator between the tractor and the implement carried (for example, in the case of a quick coupling), the provisions of point 2.3.2.7.3 do not apply.2.3.2.7.5.The operating manual should contain specific information on the dangerous points located at the front of the plane defined in the first sentence of point 2.3.2.7.1.2.3.2.8.Front three-point coupling2.3.2.8.1.At each point of the lifting unit's travel n — but not for the extreme upper and lower reaches 0,1 n — a minimum safety margin of 25 mm must be maintained between the moving parts together with a minimum angle of 30o or a safety margin of 25 mm in the case of the change of angularity caused by the parts in shear with each other. Travel n′ reduced by 0,1 n at both its upper and lower ends, is defined as follows (see also Figure 4).2.3.2.8.2.For travel n of the hydraulic lifting unit, extreme lower position A of the coupling point of the lower link is limited by dimension "14" in accordance with ISO Standard 8759, Part 2, while extreme upper position B is limited by the maximum hydraulic travel. Traven n′ reduced upwards and downwards by 0,1 n and the vertical distance between A′ and B′.2.3.2.8.3.If, for the lower links of a front three-point coupling, coupling devices (such as a rapid-action coupling) are used which do not require the presence of a person between the tractor and the implement attached during coupling, the requirements under 2.3.2.8.1 do not apply within the reach of a radius of 250 mm from the points at which the lower links are coupled to the tractor. However, a minimum safety margin of 25 mm from neighbouring parts within the defined travel n′ must in any case be maintained around the outside of the travel rods/cylinders.2.3.2.9.Driving seat and environmentWhen he is in a sitting position, all pinching of shearing points must be out of range of the driver's hands or feet. This requirement is considered to have been met if the following conditions are fulfilled:2.3.2.9.1.The driver's seat is at the mid-point in its longitudinal and vertical adjustment range. The driver's reach limit is divided into zones A and B. A central spherical point of these zones is 60 mm in front of and 580 mm above the seat reference point (see Figure 5). Zone A consists of a sphere having a diameter of 550 mm while zone B is located between that sphere and a sphere having a radius of 1000 mm. 01989L0173-20060327_en_img_11

2.3.2.9.2.A safety distance of 120 mm in zone A and 25 mm in zone B is maintained near the pinching and shearing points, whilst a minimum angle of 30o is maintained in the case of shearing parts causing a change in angularity.2.3.2.9.3.In zone A, only the pinching and shearing points caused by parts set in motion by an outside energy source must be taken into account.2.3.2.9.4.If a dangerous point is due to the presence of structural parts adjacent to the seat, a safety distance of a least 25 mm is maintained between that structural part and the seat. There is no dangerous point between the seat backrest and the adjacent structural parts located behind that backrest if the adjacent structural parts are smooth and the seat backrest itself is rounded in the surrounding area and has no sharp points.2.3.2.10.Passenger seat (if any)2.3.2.10.1.If parts may constitute a danger for the feet, provision must be made for protective devices within a hemispherical radius of 800 mm starting from the forward edge of the seat cushion and pointing downwards.2.3.2.10.2.As described in section 2.3.2.9 (see Figure 6) the dangerous points in zones A and B must be protected within a sphere whose centre is 670 mm above the centre of the front edge of the passenger seat. 01989L0173-20060327_en_img_12

2.3.2.11.Narrow-track tractors (tractors with a track as defined in the second indent of Article 1 of Directive 87/402/EEC).2.3.2.11.1.In the case of narrow-track tractors, the requirements of section 2.3.2.9 do not apply to the zone situated below a plane inclined at 45o to the rear and transverse to the direction of travel, and passing through a point located 230 mm behind the seat index point (see Figure 7). If there are any dangerous points in this zone, corresponding warnings must be affixed to the tractor. 01989L0173-20060327_en_img_13

2.3.2.11.2.Sections II.1 and II.2 of Annex I to Directive 80/720/EEC apply to access to the driver's seat.2.3.2.11.3.Section I.6 of Annex I to Directive 80/720/EEC applies to control devices.2.3.2.11.4.In front of a reference plane which passes at right angles to the longitudinal axis of the vehicle and through the centre of the load-free pedal (clutch and/or service brake), very hot exhaust components must be protected if located within 300 mm in the upper zone (700 mm above ground level) and within 150 mm in the lower zone (see Figure 8). Laterally, the area to be protected is limited by the external outline of the tractor and the external outline of the exhaust system.Very hot exhaust system components passing beneath the entry step must be covered in their vertical projection or otherwise thermally protected. 01989L0173-20060327_en_img_14

A clearance zone smaller than that illustrated in Figure 9 and Table 6 is permissible in addition to the zones referred to in sections 2.3.2.9 and 2.3.2.10 in the case of narrow-track tractors where wheel guards are also used to scrape off earth stuck to the wheels.2.3.2.16.Hot surfacesHot surfaces which can be reached by the operator during normal operation of the tractor shall be covered or insulated. This applies to hot surfaces which are near to steps, handrails, handholds and integral tractor parts used as boarding means and which may be inadvertently touched.2.3.2.17.Battery terminal coverNon-earthed terminals must be protected against unintentional short-circuiting.2.4.Method of determining the seat index point2.4.1.GeneralThe method and device used in defining the index point for any type of upholstered seat are described below.2.4.2.DefinitionsSeat index point (SIP):Point situated in the vertical median longitudinal plane of the SIP locating device represented in Figure 10 which is placed on the driving seat in accordance with points 2.4.4 and 2.4.6.The seat index point is established in relation to the vehicle and does not move as a function of the seat adjustments and/or oscillations.2.4.3.Device for determining the seat index point (SIP)The device for determining the SIP must be as shown in Figure 10. The mass of that device is 6 ± 1 kg and its underside must be flat and polished.2.4.4.Seat setting for determination of index point (SIP)Where a seat and its suspension can be regulated, the seat is regulated as follows before the index point is determined:(a)all of the adjustments — back/forth, height and rake — must be in their mid-position. If this is not the case, the closest adjustment either above or below the mid-position should be used;(b)adjustable suspension must be adjusted in such a way that the suspension is at mid-travel with the locating device in position and loaded. The suspension may be locked mechanically in that position while the index point (SIP) is determined;(c)non-adjustable suspension may be locked in the vertical position that is achieved with the locating device in place and loaded;(d)if the adjustments mentioned above conflict with the manufacturer's specific instructions, these must be followed in such a way as to obtain the setting recommended for a 75-kg driver.NB:A 75-kg driver offers an approximation of the locating device in position on the seat and loaded with a mass of 65 kg.2.4.5.Determination of the three reference axes x′, y′, and z′ for the SIPThe coordinates must be established as follows:(a)location, on one side of the seat mounting, of the attachment hole that is in the most rear position;(b)if the axis of this hole is parallel to the pivot axis defined on the device, it is taken as axis y′, (pointing from left to right in relation to a seated driver — see Figure 11);(c)if the axis of this hole is parallel to the vertical plane passing through the centre line of the seat, the straight line is taken as axis y′ which runs parallel to the pivot axis referred to and passes through the point of intersection between the supporting plane of the seat and the hole axis referred to above (see Figure 12).(d)in all other cases, axis y′ is established in accordance with the parameters relating to the seat being measured;(e)axes x′ and z′ are defined as intersections of the horizontal and vertical planes passing through y′ with the vertical plane through the seat centre line. Axes x′ and z′ point forwards and upwards (see Figures 11 and 12).2.4.6.Method of determining the seat index point (SIP)The seat index point (SIP) is determined by using the device shown in Figure 10 and by proceeding in the following manner:(a)the seat is covered with a piece of cloth in order to facilitate correct positioning of the device;(b)the device is positioned on the seat cushion (without additional mass) by pushing it rearwards against the backrest;(c)masses are added to bring the total mass of the device from 6 ± 1 kg to 26 ± 1 kg. The centre of vertical force must be 40 mm ahead of the seat index point mark on the horizontal part of the device (see Figure 10);(d)a horizontal force of about 100 N is applied twice to the device on the seat index point, as set out in figure 10;(e)other masses are added to bring the total mass of the device from 26 ± 1 kg to 65 ± 1 kg. The centre of the vertical force of the masses added must be 40 mm ahead of the seat index point mark on the horizontal part of the device (see Figure 10);(f)on both sides of the seat in two vertical planes, equidistant from the median longitudinal line of the seat, the coordinates, as defined in point 2.4.5, of the intersections of those planes on the axis of the seat index point marked by the device must be measured to ± 1 mm.The arithmetical mean values of the measurements taken in the two planes are recorded as SIP coordinates;(g)the conditions resulting from the method of determination, and which diverge from the procedure set out in this Annex, or which may be the source of errors as regards their results, may be noted, as may their causes. 01989L0173-20060327_en_img_16

This point is designated as O below;9.2.5.1.2.the straight line OQ which is the horizontal straight line passing through the reference point and perpendicular to the median longitudinal plane of the tractor;9.2.5.2.zone I is the windscreen zone determined by the intersection of the windscreen with the four planes defined below:P1a vertical plane passing through O and forming an angle of 15o to the left of the median longitudinal plane of the tractor,P2a vertical plane symmetrical to P1 about the median longitudinal plane of the tractor.If this is not possible (in the absence of a symmetrical median longitudinal plane, for instance) P2 is the plane symmetrical to P1 about the longitudinal plane of the tractor passing through the reference point,P3a plane passing through the straight line OQ and forming an angle of 10o above the horizontal plane,P4a plane passing through the straight line OQ and forming an angle of 8o below the horizontal plane.9.2.5.3.In the case of tractors for which it is not possible to determine zone I, as defined in point 9.2.5.2 of this Annex, zone I′ consists of the whole surface of the windscreen.9.2.6.Interpretation of resultsA type of windscreen is considered satisfactory as regards optical distortion if, in the four samples submitted for testing, optical distortion does not exceed a maximum value of 2′ of an arc in either zone I or zone I′.9.2.6.1.No measurement must be performed within a 100-mm-wide peripheral zone.9.2.6.2.In the case of divided windscreens, no measurement is performed within a band 35 mm in width, starting from the edge of the pane, which may be adjacent to the screen divider.9.3.Secondary-image separation test9.3.1.ScopeTwo test methods are recognized:target test, andcollimation telescope test.These test methods may be used for component type-approval, quality-control or product-evaluation purposes, as appropriate.9.3.1.1.Target test9.3.1.1.1.ApparatusThis method involves viewing an illuminated target through the safety-glass pane. The target may be designed in such a way that the test can be carried out on a simple go/no go basis.The target must preferably be of one of the following types:(a)an illuminated ring target whose outer diameter, D, subtends an angle of n minutes of arc at a point situated at x metres (Figure 11a); or(b)an illuminated ring and spot target whose dimensions are such that the distance, D, from a point on the edge of the spot to the nearest point on the inside of the circle subtends an angle of n minutes of arc at a point situated at x metres (Figure 11b);where:n is the limit value of secondary-image separation,x is the distance from the safety-glass pane to the target (not less than 7 m),D is given by the formula:D = x · tan nThe illuminated target consists of a light box, acpproximately 300 mm × 300 mm × 150 mm, whose front is most conveniently constructed of glass masked with opaque black paper or coated with matt black paint. The box is illuminated by a suitable light source. The inside of the box is coated with matt white paint. It may be convenient to use other forms of target, such as that shown in Figure 14. It is also acceptable to replace the target system by a projection system and to view the resulting images on a screen.9.3.1.1.2.ProcedureMount the safety-glass pane at the specified rake angle on a suitable stand in such a way that the observation is carried out in the horizontal plane passing through the centre of the target.The light box must be viewed, in a dark or semi-dark room, through each part of the area being examined, in order to detect the presence of any secondary image associated with the illuminated target. Rotate the safety-glass pane as necessary to ensure that the correct direction of view is maintained. A monocular may be used for viewing.9.3.1.1.3.Expression of resultsDetermine whether:when target (a) (see figure 11a) is used, the primary and secondary image of the circle separate, i.e. whether the limit value of n is exceeded, orwhen target (b) (see figure 11b) is used, the secondary image of the spot shifts beyond the point of tangency with the inside edge of the circle, i.e. whether the limit value of n is exceeded. 01989L0173-20060327_en_img_32

9.3.1.2.Collimation telescope testIf necessary, the procedure described in this section is applied.9.3.1.2.1.ApparatusThe apparatus comprises a collimator and a telescope and may be set up in accordance with Figure 13. However, any equivalent optical system may be used.9.3.1.2.2.ProcedureThe collimation telescope forms at infinity the image of a polar-coordinate system with a bright point at its centre (see Figure 14). In the focal plane of the observation telescope, a small opaque spot with a diameter slightly larger than of the projected bright point is placed on the optical axis, thus obscuring the bright point. 01989L0173-20060327_en_img_35

9.3.1.2.2.When a test piece which exhibits a secondary image is placed between the telescope and the collimator, a second, less bright point appears at a certain distance from the centre of the polar-coordinate system. The secondary-image separation can be read out as the distance between the points seen through the observation telescope (see Figure 14). (The distance between the dark spot and the bright point at the centre of the polar-coordinate system represents the optical deviation.)9.3.1.2.3.Expression of resultsThe safety-glass pane is first examined by a simple scanning technique to establish the area giving the strongest secondary image. That area is then examined by the collimator telescope system at the appropriate angle of incidence. The maximum secondary-image separation is measured.9.3.1.3.The direction of observation in the horizontal plane must be maintained approximately normal to the trace of the windscreen in that plane.9.3.2.The measurements are performed according to tractor category in the zones defined in section 9.2.2.9.3.2.1.Tractor typeThe test must be repeated if the windscreen is to be mounted on a tractor of a type which has a forward field of vision different from that of the tractor for which the windscreen has already been approved.9.3.3.Indices of difficulty of the secondary characteristics9.3.3.1.Nature of the material

9.3.3.2.Other secondary characteristicsNo other secondary characteristics are involved.9.3.4.Number of samplesFour samples must be submitted for testing.9.3.5.Interpretation of resultsA type of windscreen is considered satisfactory as regards secondary-image separation if, in the four samples submitted for testing, separation of the primary and secondary image does not exceed a maximum value of 15′ of an arc.9.3.5.1.No measurement must be carried out in a 100 mm-wide peripheral zone.9.3.5.2.In the case of divided windscreens no measurement may be performed within a band 35 mm in width, starting from the edge of the pane, which may be adjacent to the screen divider.9.4.Identification of colours testWhen a windscreen is tinted in the zones defined in 9.2.5.2 or 9.2.5.3, four windscreens are tested for identifiability of the following colours:white,selective yellow,red,green,blue,amber.10.FIRE-RESISTANCE TEST10.1.Purpose and scope of applicationThis method enables the horizontal burning rate of materials used in the occupant compartment of tractors after exposure to a small flame to be determined. This method permits testing of materials and components of a tractor's interior equipment individually or in combination up to a thickness of 15 mm. It is used to judge the uniformity of production lots of such materials with respect to their burning behaviour. Because of the many differences between the real-world situation (application and orientation within a tractor; conditions of use; ignition source, etc.) and the precise test conditions prescribed herein, this method cannot be considered as suitable for evaluation of all true in-tractor burning characteristics.10.2.Definitions10.2.1.Burning rate: the quotient of the burnt distance measured according to this method and the time taken to burn that distance.It is expressed in millimetres per minute.10.2.2.Composite material: a material composed of several layers of similar or different materials intimately held together at their surface by cementing, bonding, cladding, welding, etc. When different materials are connected together intermittently (for example, by sewing, high-frequency welding, riveting), then in order to permit the preparation of individual samples in accordance with section 10.5 such materials are not considered as composite materials.10.2.3.Exposed side: the side which is facing towards the occupant compartment (passenger compartment) when the material is mounted in the tractor.10.3.PrincipleA sample is held horizontally in a U-shaped holder and is exposed to the action of a defined low-energy flame for 15 seconds in a combustion chamber, the flame acting on the free end of the sample. The test determines whether and when the flame is extinguished or the time which the flame requires to proceed over a measured distance.10.4.Apparatus10.4.1.Combustion chamber (Figure 15), preferably of stainless steel, having the dimensions given in Figure 16. The front of the chamber contains a flame-resistant observation window, which may cover the entire front and which can be constructed as an access panel.The bottom of the chamber has vent holes, and the top has a vent slot all around. The combustion chamber is placed on four feet, 10 mm high.The chamber may have a hole at one end for the introduction of the sample holder containing the sample; in the opposite end, a hole is provided for the gas supply line. Melted material is caught in a pan (see Figure 17) which is placed on the bottom of the chamber between vent holes without covering any vent hole area. 01989L0173-20060327_en_img_36

10.4.2.Sample holder, consisting of two U-shaped metal plates or frames of corrosion-proof material. Dimensions are given in Figure 18.The lower plate is equipped with pins and the upper one with corresponding holes, in order to ensure a consistent holding of the sample. The pins also serve as measuring points at the beginning and end of the burning distance.A support is provided in the form of heat-resistant wires 0,25 mm in diameter spanning the frame at 25 mm intervals over the bottom U-shaped frame (see Figure 19). 01989L0173-20060327_en_img_39

The plane of the lower side of samples must be 178 mm above the floor plate. The distance of the front edge of the sample holder from the end of the chamber must be 22 mm; the distance of the longitudinal sides of the sample holder from the sides of the chamber must be 50 mm (all inside dimensions). (See Figures 15 and 16.)10.4.3.Gas burner. The small ignition source is provided by a Bunsen burner having an inside diameter of 9,5 mm. It is so located in the test cabinet that the centre of its nozzle is 19 mm below the centre of the bottom edge of the open end of the sample (see Figure 16).10.4.4.Test gas. The gas supplied to the burner must have a calorific value of about 38 MJ/m3 (for example natural gas).10.4.5.Metal comb, at least 110 mm in length, with seven or eight smooth rounded teeth per 25 mm.10.4.6.Stop-watch, accurate to 0,5 second.10.4.7.Fume cupboard. The combustion chamber may be placed in a fume cupboard assembly provided that the latter's internal volume is at least 20 times, but not more than 110 times, greater than the volume of the combustion chamber and provided that no single height, width, or length dimension of the fume cupboard is greater than 2½ times either of the other two dimensions.Before the test, the vertical velocity of the air through the fume cupboard is measured 100 mm forward of and to the rear of the ultimate site of the combustion chamber. It must be between 0,10 and 0,30 m/s in order to avoid possible discomfort to the operator from combustion products. It is possible to use a fume cupboard with natural ventilation and an appropriate air velocity.10.5.Samples10.5.1.Shape and dimensionsThe shape and dimensions of samples are given in Figure 20. The thickness of the sample corresponds to the thickness of the product to be tested. It must not be more than 13 mm. When sample taking so permits, the sample must have a constant section over its entire length. When the shape and dimensions of a product do not permit taking a sample of the given size, the following minimum dimensions must be observed:(a)for samples having a width of 3 to 60 mm, the length must be 356 mm. In this case the material is tested over the product's width;(b)for samples having a width of 60 to 100 mm, the length must be at least 138 mm. In this case the potential burning distance corresponds to the length of the sample, the measurement starting at the first measuring point;(c)samples less than 60 mm wide and less than 356 mm long, and samples 60 to 100 mm wide and less than 138 mm long, cannot be tested according to the present method, nor can samples less than 3 mm wide.10.5.2.SamplingAt least five samples are to be taken from the material under test. In materials having burning rates differing according to the direction of the material (this being established by preliminary tests) the five (or more) samples are to be taken and placed in the test apparatus in such a way that the highest burning rate will be measured. When the material is supplied in set widths, a length of at least 500 mm covering the entire width is cut. From the piece so cut, the samples are to be taken at not less than 100 mm from the edge of the material and at points equidistant from each other.Samples are to be taken in the same way from finished products when the shape of the product so permits. If the thickness of the product is over 13 mm it must be reduced to 13 mm by a mechanical process applied to the side which does not face the passenger compartment.Composite materials (see 10.2.2) are to be tested as if they were homogeneous.In the case of materials comprising superimposed layers of different composition which are not composite materials, all the layers of material included within a depth of 13 mm from the surface facing towards the passenger compartment are to be tested individually. 01989L0173-20060327_en_img_41

10.5.3.ConditioningThe samples are to be conditioned for at least 24 hours, but no more than 7 days, at a temperature of 23 ± 2 oC and a relative humidity of 50 ± 5 %, and maintained under these conditions until immediately prior to testing.10.6.Procedure10.6.1.Place samples with napped or tufted surfaces on a flat surface, and comb twice against the nap using the comb (10.4.5).10.6.2.Place the sample in the sample holder (10.4.2) so that the exposed side faces downwards, towards the flame.10.6.3.Adjust the gas flame to a height of 30 mm using the mark in the chamber, the air intake of the burner being closed. The flame must burn for at least one minute, for stabilization, before the first test is started.10.6.4.Push the sample holder into the combustion chamber so that the end of the sample is exposed to the flame, and after 15 seconds cut off the gas flow.10.6.5.Measurement of burning time starts at the moment when the foot of the flame passes the first measuring point. Observe the flame propagation on the side (upper or lower) which burns faster.10.6.6.Measurement of burning time is completed when the flame has come to the last measuring point or when the flame is extinguished before reaching that point. If the flame does not reach the last measuring point, measure the burnt distance up to the point where the flame was extinguished. Burnt distance is the part of the sample destroyed, on the surface or inside, by burning.10.6.7.If the sample does not ignite or does not continue burning after the burner has been extinguished, or the flame goes out before reaching the first measuring point, so that no burning time is measured, note in the test report that the burning is 0 mm/minute.10.6.8.When running a series of tests or performing repeat tests, make sure before starting a test that the temperature of the combustion chamber and sample-holder does not exceed 30 oC.10.7.CalculationThe burning rate, B, in millimetres per minute, is given by the formula:B = st × 60where:s is the burnt distance, in millimetres,t is the time, in seconds, taken to burn the distance s.10.8.Indices of difficulty of the secondary characteristicsNo secondary characteristics are involved.10.9.Interpretation of resultsPlastic-coated (2.3) and plastic safety glazing (2.4) are considered satisfactory from the point of view of burning behaviour (fire resistance) if the burn rate does not exceed 250 mm/minute.11.TESTING OF RESISTANCE TO CHEMICAL AGENTS11.1.Chemical agents to be used11.1.1.Non-abrasive soapy solution: 1 % by weight of potassium oleate in de-ionized water.11.1.2.Window-cleaning product: aqueous solution of isopropanol and dipropylene glycol monomethyl ether, each at a concentration of 5 to 10 % by weight, and of ammonium hydroxyde at a concentration of 1 to 5 % by weight.11.1.3.Non-dilute denatured alcohol: one part by volume of methyl alcohol in 10 parts by volume of ethyl alcohol.11.1.4.Reference gasoline mixture of 50 % by volume of toluene, 30 % by volume of 2,2,4-trimethylpentane, 15 % by volume of 2,4,4-trimethyl-1-pentane and 5 % by volume of ethyl alcohol.11.1.5.Reference kerosene: mixture of 50 % by volume of n-octane and 50 % by volume of n-decane.11.2.Test methodTwo 180 × 25 mm test pieces are each to be tested with chemical agents as provided for in section 11.1, a new test piece being used for each test and product. After each test the pieces are to be cleaned in accordance with the manufacturer's instruction, and then conditioned for 48 hours at a temperature of 23 ± 2 oC and a relative humidity of 50 ± 5 %. These conditions are to be maintained during the tests. The test pieces are to be completely immersed in the test liquid for one minute, withdrawn and then immediately dried with a (clean) absorbent cotton cloth.11.3.Indices of difficulty of the secondary characteristics

No secondary characteristic is involved.11.4.Interpretation of the results11.4.1.The test for resistance to chemical agents is considered to be positive if the test pieces display no softening, stickiness, surface cracking or apparent loss of transparency.11.4.2.A series of test pieces submitted for component type-approval are considered satisfactory as regards resistance to chemical agents if one of the following conditions has been met:11.4.2.1.all the tests give satisfactory results;11.4.2.2.a test having given an unsatisfactory result, a further series of tests must be carried out on a new set of test pieces and give satisfactory results.ANNEX III DTOUGHENED-GLASS WINDSCREENS1.DEFINITION OF TYPEToughened-glass windscreens are deemed to belong to different types if they differ in at least one of the following principal or secondary characteristics.1.1.The principal characteristics are as follows:1.1.1.the trade name or mark;1.1.2.the shape and dimensions.Toughened-glass windscreens are considered as belonging to one or other of two groups for the purposes of the fragmentation and mechanical-properties tests, i.e.:1.1.2.1.flat windscreens, and1.1.2.2.curved windscreens;1.1.3.the thickness category in which the nominal thickness "e" lies (a manufacturing tolerance of ± 0,2 mm being allowed):

— category I:		e ≤ 4,5 mm
— category II:	4,5 mm <	e ≤ 5,5 mm
— category III:	5,5 mm <	e ≤ 6,5 mm
— category IV:	6,5 mm <	e

1.2.The secondary characteristics are as follows:1.2.1.nature of the material (polished (plate) glass, float glass, sheet glass),1.2.2.colouring (colourless or tinted),1.2.3.the incorporation or absence of conductors,1.2.4.the incorporation or absence of obscuration bands.2.FRAGMENTATION TEST2.1.Indices of difficulty of the secondary characteristics2.1.1.Only the nature of the material is involved.2.1.2.Float glass and sheet glass are considered to have the same index of difficulty.2.1.3.The fragmentation tests must be repeated on transition from polished (plate) glass to float glass or sheet glass, and vice versa.2.1.4.The tests must be repeated if obscuration bands other than painted bands are used.2.2.Number of samplesSix samples from the smallest-developed-area series and six samples from the largest-developed-area series, selected as prescibed in Annex III M, are to be tested.2.3.Different zones of glassA toughened-glass windscreen must comprise two main zones, FI and FII. It may also comprise an intermediate zone, FIII.These zones are as defined below:2.3.1.zone FI: peripheral zone of fine fragmentation, at least 7 cm wide, all round the edge of the windscreen and including an outer strip 2 cm wide not subjected to assessment;2.3.2.zone FII: visibility zone of varying fragmentation, always including a rectangular part at least 20 cm high and 50 cm long.2.3.2.1.The centre of the rectangle is inside a circle having a radius of 10 cm centred on the projection of the reference point.2.3.2.2.In the case of tractors for which it is not possible to determine the reference point, the position of the visibility zone must be indicated in the test report.2.3.2.3.The height of the above rectangle may be reduced to 15 cm for windscreens which are less than 44 cm high;2.3.3.zone FIII: intermediate zone, not more than 5 cm wide, between zones FI and FII.2.4.Test methodThe method used is that described in section 1 of Annex III C.2.5.Points of impact (see Annex III N, Figure 2).2.5.1.The points of impact are selected as follows:point 1: in the central part of zone FII in an area of high or low strees;point 2: in zone FIII, as near as possible to the vertical plane of symmetry of zone FII;points 3 and 3′: 3 cm from the edges of one median of the sample; when there is a tong mark, one of the breakage points shall be near the edge bearing the tong mark and the other near the opposite edge;point 4: at the place where the radius of curvature is smallest on the longest median;point 5: 3 cm from the edge of the sample at the place where the radius of curvature of the edge is smallest, either to the left or to the right.2.5.2.A fragmentation test is performed at each of the points 1, 2, 3, 3′, 4 and 5.2.6.Interpretation of results2.6.1.A test is deemed to have given a satisfactory result if fragmentation satisfies all the conditions given in points 2.6.1.1, 2.6.1.2 and 2.6.1.3 below.2.6.1.1.Zone FI2.6.1.1.1.The number of fragments in any 5 × 5 cm square is not less than 40 nor more than 350; however, in the case of a count of less than 40, if the number of fragments in any 10 × 10 cm square containing the 5 × 5 cm square is not less than 160, this is acceptable.2.6.1.1.2.For the purposes of the above rule, a fragment extending across a side of a square counts as half a fragment.2.6.1.1.3.Fragmentation is not checked in a strip 2 cm wide round the edge of the samples, this strip representing the frame of the glass, nor within a radius of 7,5 cm from the point of impact.2.6.1.1.4.A maximum of three fragments of an area exceeding 3 cm2 is allowed. No two of these fragments must be contained within the same 10 cm diameter circle.2.6.1.1.5.Elongated fragments may be permitted provided that their ends are not knife-edged and that their length does not exceed 7,5 cm, except in the case provided for in point 2.6.2.2 below. If these elongated fragments extend to the edge of the glass, they must not form an angle of more than 45o with it.2.6.1.2.Zone FII2.6.1.2.1.The residual visibility after shattering is checked in the rectangular area defined in point 2.3.2. In that rectangle the aggregate surface area of the fragments of more than 2 cm2 must represent not less than 15 % of the area of the rectangle; however, in the case of windscreens less than 44 cm high, or whose angle of installation is less than 15o from the vertical, the visibility percentage must be equal to 10 % at least of the surface of the corresponding rectangle.2.6.1.2.2.No fragment must have an area of more than 16 cm2 except in the case provided for in point 2.6.2.2.2.6.1.2.3.Within a radius of 10 cm from the point of impact, but only in that part of the circle which is included in zone FII, three fragments having an area of more than 16 cm2 but less than 25 cm2 are allowed.2.6.1.2.4.Fragments must be substantially regular in shape and free from points of the type described in point 2.6.1.2.4.1. However, not more than 10 irregular fragments are allowed in any 50 × 20 cm rectangle and not more than 25 over the whole surface of the windscreen.No such fragment must present a point more than 35 mm long measured in accordance with point 2.6.1.2.4.1.2.6.1.2.4.1.A fragment is considered as an irregular fragment if it cannot be inscribed in a circle of 40 mm in diameter, if it has at least one point more than 15 mm long when measured from the top of the point to the section whose width is equal to the glazing thickness, and if it has one or more points having a top angle smaller than 40o.2.6.1.2.5.Fragments of elongated shape are allowed in zone FII as a whole, provided they do not exceed 10 cm in length, except in the case provided for in point 2.6.2.2.2.6.1.3.Zone FIIIFragmentation in this zone must have characteristics intermediate between those of the fragmentations respectively allowed for the two neighbouring zones (FI and FII).2.6.2.A windscreen submitted for component type-approval is considered satisfactory from the point of view of fragmentation if at least one of the following conditions is fulfilled:2.6.2.1.when all the tests carried out using the points of impact defined in point 2.5.1 have given a satisfactory result;2.6.2.2.when one test among all those carried out using the points of impact prescribed in point 2.5.1 has given an unsatisfactory result, taking account of deviations which do not exceed the following limits:zone FI: not more than five fragments between 7,5 and 15 cm long;zone FII: not more than three fragments of between 16 and 20 cm2 in area located outside the circle having a radius of 10 cm centred on the point of impact;zone FIII: not more than four fragments between 10 and 17,5 cm long,and is repeated on a new sample, which either conforms to the requirements of section 2.6.1 or presents deviations within the above specified limits.2.6.2.3.when two tests among all the tests carried out using the points of impact prescribed in point 2.5.1 have given an unsatisfactory result for deviations not exceeding the limits specified in point 2.6.2.2 and a further series of tests carried out on a new set of samples conform to the requirements of section 2.6.1, or not more than two samples of the new set present deviations within the above specified limits of point 2.6.2.2.2.6.3.If the abovementioned deviations are found, they must be noted in the test report and photographs of the relevant parts of the windscreen attached to the report.3.HEADFORM TEST3.1.Indices of difficulty of the secondary characteristicsNo secondary characteristic is involved.3.2.Number of samples3.2.1.For each group of toughened-glass windscreens, four samples having approximately the smallest developed area and four samples having approximately the largest developed area, all eight samples being of the same types as those selected for the fragmentation tests (see 2.2) are subjected to testing.3.2.2.Alternatively, at the discretion of the laboratory conducting the tests, for each category of windscreen thickness, six test pieces of the dimension (1100 × 500 mm) + 5/− 2 mm are subjected to testing.3.3.Test method3.3.1.The method used is that described in section 3 of Annex III C.3.3.2.The height of drop is 1,50 m + 0/− 5 mm.3.4.Interpretation of results3.4.1.The test is deemed to have given a satisfactory result if the windscreen or the test piece is fractured.3.4.2.A set of samples submitted for component type-approval are considered satisfactory from the point of view of the headform test if either of the two following conditions is fulfilled:3.4.2.1.all the tests have given a satisfactory result;3.4.2.2.a test having given an unsatisfactory result, a further series of tests must be carried out on a new set of samples and give satisfactory results.4.OPTICAL QUALITIESThe requirements concerning optical qualities set out in section 9 of Annex III C apply to every type of windscreen.ANNEX III EUNIFORMLY TOUGHENED-GLASS PANES OTHER THAN WINDSCREENSThis type of uniformly toughened-glass pane can also be used for windscreens for tractors.1.DEFINITION OF TYPEUniformly toughened glass panes, are deemed to belong to different types if they differ in at least one of the following principal or secondary characteristics.1.1.The principal characteristics are as follows:1.1.1.the trade name mark;1.1.2.the nature of the toughening process (thermal or chemical);1.1.3.the shape category; two categories are distinguished:1.1.3.1.flat glass panes,1.1.3.2.flat and curved glass panes.1.1.4.The thickness category in which the nominal thickness "e" lies (a manufacturing tolerance of ± 0,2 mm being allowed):

— category I:		e ≤ 3.5
— category II:	3,5 mm <	e ≤ 4.5
— category III:	4,5 mm <	e ≤ 6.5
— category IV:	6,5 mm <	e
