Directive 2001/56/EC of the European Parliament and of the Councilof 27 September 2001relating to heating systems for motor vehicles and their trailers, amending Council Directive 70/156/EEC and repealing Council Directive 78/548/EEC THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION, Having regard to the Treaty establishing the European Community, and in particular Article 95 thereof, Having regard to the proposal from the CommissionOJ C 326, 24.10.1998, p. 4 and OJ C 116 E, 26.4.2000, p. 2., Having regard to the opinion of the Economic and Social CommitteeOJ C 101, 12.4.1999, p. 15., Acting in accordance with the procedure laid down in Article 251 of the TreatyOpinion of the European Parliament of 13 April 1999 (OJ C 219, 30.7.1999, p. 58), Council Common Position of 17 November 2000 (OJ C 36, 2.2.2001, p. 1) and Decision of the European Parliament of 14 March 2001 (not yet published in the Official Journal). Council Decision of 26 June 2001., Whereas: (1)Council Directive 78/548/EEC of 12 June 1978 on the approximation of the laws of the Member States relating to heating systems for the passenger compartment of motor vehiclesOJ L 168, 26.6.1978, p. 40. was adopted as one of the separate directives of the EC type-approval procedure which has been established by Council Directive 70/156/EEC of 6 February 1970 on the approximation of the laws of the Member States relating to the type-approval of motor vehicles and their trailersOJ L 42, 23.2.1970, p. 1. Directive as last amended by Directive 98/91/EC of the European Parliament and of the Council (OJ L 11, 16.1.1999, p. 25).. Consequently, the provisions laid down in Directive 70/156/EEC relating to vehicle systems, components and separate technical units apply to Directive 78/548/EEC. (2)In particular, under Article 3(4) and Article 4(3) of Directive 70/156/EEC each separate directive is to be accompanied by an information document incorporating the relevant items of Annex I to Directive 70/156/EEC and also a type-approval certificate based on Annex VI thereto in order that type-approval may be computerised. (3)In the light of technical progress, combustion heaters, usually fuelled by diesel, petrol or liquefied petroleum gas, are now fitted to many types of vehicle in order to provide heat for the passenger compartment (e.g. of buses), the load area (e.g. of trucks and trailers) or the sleeping compartment (e.g. of trucks and motor caravans) so that heat can be provided efficiently and without the noise and gaseous emissions associated with running the propulsion engine when the vehicle is parked. For reasons of safety, it is necessary to extend the scope to include requirements for combustion heaters, and for their installation. Such requirements should correspond to the highest standards consistent with current technology. (4)It is necessary to provide for type-approval for combustion heaters as components and for vehicles in which a combustion heater is installed. (5)It will be necessary to supplement this Directive with additional safety requirements for liquefied petroleum gas (LPG) combustion heaters by the addition of an Annex. (6)The measures necessary for the implementation of this Directive should be adopted in accordance with Council Decision 1999/468/EC of 28 June 1999 laying down the procedures for the exercise of implementing powers conferred on the CommissionOJ L 184, 17.7.1999, p. 23..
