Consequently, the provi- sions 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 incorpor- ating the relevant items of Annex [ 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 cara- vans) so that heat can be provided efficiently and without the noise and gaseous emissions associated with (') OJ C 326, 24.10.1998, p. 4 and O] C 116 E, 26.4.2000, p. 2.

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 combus- tion 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 Commission (6).

Article 2 No Member State may refuse to grant EC type-approval or national type-approval of a type of vehicle or of a type of heating system on grounds relating to the heating system for the passenger compartment or load area if the system satisfies the requirements set out in the Annexes. Article 3 No Member State may refuse or prohibit the sale, registration, entry into service or use of any vehicle or the sale, entry into service or use of any heating system on grounds relating to the heating system for the passenger compartment or load area if the system satisfies the requirements set out in the Annexes.
