21.2.2014 Official Journal of the European Union L 531 (Non-legislative acts) REGULATIONS COMMISSION DELEGATED REGULATION (EU) No 134/2014 of 16 December 2013 supplementing Regulation (EU) No 168/2013 of the European Parliament and of the Council with regard to environmental and propulsion unit performance requirements and amending Annex V thereof (Text with EEA relevance) THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Regulation (EU) No 168/2013 of the European Parliament and of the Council of 15 January 2013 on the approval and market surveillance of two- or three-wheel vehicles and quadricycles (1), and in particular Article 18(3), Article 23(12), Article 24(3) and Article 74 thereof, Whereas: The term ‘L-category vehicles' covers a wide range of light vehicle types with two, three or four wheels, e.g. powered cycles, two- and three-wheel mopeds, two- and three-wheel motorcycles, motorcycles with side-cars and light four-wheel vehicles (quadricycles) such as on-road quads, all-terrain quads and quadrimobiles. Regulation (EU) No 168/2013 provides for the possibility of applying regulations of the United Nations Economic Commission for Europe (UNECE) for the purpose of EU whole vehicle type-approval. Under that Regulation, () O] L 60, 2.3.2013, p. 52. type-approval in accordance with UNECE regulations which apply on a compulsory basis is regarded as EU type-approval. The compulsory application of UNECE regulations helps avoiding duplication not only of technical requirements but also of certification and administrative procedures. In addition, type-approval that is directly based on inter- nationally agreed standards could improve market access in third countries, in particular those which are contracting parties to the Agreement of the United Nations Economic Commission for Europe concerning the adoption of uniform technical prescriptions for wheeled vehicles, equipment and parts which can be fitted to or be used on wheeled vehicles and the conditions for reciprocal recognition of approvals granted on the basis of these prescriptions (Revised 1958 Agreement), acceded by the Union by Council Decision 97/836/EC (3), and thus enhance the Union industry’s competitiveness. However, to date the available UNECE regulations are either outdated or not existing and therefore these are revisited and upgraded for technical progress. Therefore, Regulation (EU) No 168/2013 provides for the repeal of several directives concerning the approval of L- category vehicles, their systems, components and separate technical units intended for those vehicles in the areas of environmental and propulsion unit performance require- ments. For the purposes of EU type-approval those directives should be replaced first with the provisions (%) Council Decision 97/836/EC of 27 November 1997 with a view to accession by the European Community to the Agreement of the United Nations Economic Commission for Europe concerning the adoption of uniform technical prescriptions for wheeled vehicles, equipment and parts which can be fitted to or be used on wheeled vehicles and the conditions for reciprocal recognition of approvals granted on the basis of these prescriptions (Revised 1958 Agreement) (O] L 346, 17.12.1997, p. 78).
