L 262[34 Official Journal of the European Union 14.10.2003 COMMISSION DECISION of 3 October 2003 on the procedure for attesting the conformity of construction products pursuant to Article 20(2) of Council Directive 89/106/EEC as regards metal frame building kits, concrete frame building kits, prefabricated building units, cold storage room kits and rock-fall protection kits (notified under document number C(2003) 3452) (Text with EEA relevance) (2003/728/EC) THE COMMISSION OF THE EUROPEAN COMMUNITIES, Having regard to the Treaty establishing the European Community, Having regard to Council Directive 89/106/EEC of 21 December 1988 on the approximation of laws, regulations and administrative provisions of the Member States relating to construction products ('), as amended by Directive 93/68/ EEC (3), and in particular Article 13(4) thereof, Whereas: (1)  The Commission is required to select, between the two procedures under Article 13(3) of Directive 89/106/EEC for attesting the conformity of a product, the least onerous possible procedure consistent with safety. Whereas this means that it is necessary to decide whether, for a given product or family of products, the existence of a factory production control system under the responsibility of the manufacturer is a necessary and sufficient condition for an attestation of conformity, or whether, for reasons related to compliance with the criteria mentioned in Article 13(4), the intervention of an approved certification body is required. (2)  Article 13(4) requires that the procedure thus deter- mined shall be indicated in the mandates and in the technical specifications. Therefore, it is desirable to define the concept of products or family of products as used in the mandates and in the technical specifications. (3)  The two procedures provided for in Article 13(3) are described in detail in Annex III to Directive 89/106/EEC. It is necessary therefore to specify clearly the methods by which the two procedures shall be implemented, by reference to Annex III, for each product or family of products, since Annex III gives preference to certain systems. (4)  The procedure referred to in Article 13(3)(a) corresponds to the systems set out in the first possibility, without continuous surveillance, and the second and third possi- () OJ L 40, 11.2.1989, p. 12. () OJ L 220, 30.8.1993, p. 1. bilities of Annex II(2)(ii). The procedure referred to in Article 13(3)(b) corresponds to the systems set out in Annex II1(2)(i), and in the first possibility, with contin- uous surveillance, of II1(2)(ii). (5)  The measures provided for in this Decision are in accor- dance with the opinion of the Standing Committee on Construction, HAS ADOPTED THIS DECISION: Atrticle 1 The products and families of products set out in Annex I shall have their conformity attested by a procedure whereby, in addi- tion to a factory production control system operated by the manufacturer, an approved certification body is involved in assessment and surveillance of the production control and the product itself. Atticle 2 The procedure for attesting conformity as set out in Annex II shall be indicated in the mandates for Guidelines for European technical approvals. Atticle 3 This Decision is addressed to the Member States. Done at Brussels, 3 October 2003. For the Commission Erkki LIIKANEN Member of the Commission
