COUNCIL DIRECTIVE 92/54/EEC of 22 June 1992 amending Directive 77/143/EEC on the approximation of the laws of the Member States relating to roadworthiness tests for motor vehicles and their trailers (brakes)

THE COUNCIL OF THE EUROPEAN COMMUNITIES,

Having regard to the Treaty establishing the European Economic Community and in particular Article 75 thereof,

Having regard to the proposal from the Commission (1),

Having regard to the opinion of the European Parliament (2),

Having regard to the opinion of the Economic and Social Committee (3),

Whereas Directive 77/143/EEC (4) provides for the regular roadworthiness testing of all categories of vehicles listed in Annex I thereto;

Whereas that Directive provides for the adoption of separate directives for testing the standard of the items listed in Annex II thereto and the establishment of a technical committee to advise the Commission before it adopts measures to adjust roadworthiness tests to technical progress;

Whereas most Member States have adopted procedures for testing heavy commercial vehicles with regard to the condition of the braking system;

Whereas several Member States have national rules for testing the lighter vehicles, including passenger cars, and that those rules are commensurate with the scheme outlined in this Directive;

Whereas assessment of the type approval procedures for testing vehicle braking for all vehicle types shows that applying those procedures in the roadworthiness test presents some difficulty;

Whereas in-service testing should be relatively simple, quick and inexpensive;

Whereas at this stage it would be premature to set values for the required braking efficiencies, air pressure settings and build up times, etc. given the variance in test equipments and methods within the Community; whereas the aim of brake performance testing must be that a realistic judgment can be made at the time of testing that the vehicle, irrespective of its laden condition within the bounds of its gross weights, would be safe and reliable on the road and that, if tested to the technical requirements of Council Directive 71/320/EEC of 26 July 1971 on the approximation of the laws of the Member States relating to the braking devices of certain categories of motor vehicles and of their trailers (5), then it would pass;

Whereas Member States may extend the scope of the braking test to include vehicles or test items outside the scope of this Directive;

Whereas Member States may enhance the severity of the braking test or increase the frequency of testing,

HAS ADOPTED THIS DIRECTIVE:

ANNEX

'ANNEX II

The test shall cover at least the items listed below, since these refer to the obligatory equipment of the vehicle tested in the Member State in question.

The tests covered by this Annex may be carried out visually without disassembly of vehicle parts.

Where the vehicle is found to be defective with regard to the test items below, the competent authorities in the Member States shall adopt a procedure for setting the conditions under which the vehicle may be used before passing another roadworthiness test.

VEHICLES IN CATEGORIES 1, 2, 3, 4, 5 AND 6
