28.5.2005 Official Journal of the European Union L 135/37 COMMISSION DECISION of 25 May 2005 establishing the classes of external fire performance of roofs and roof coverings for certain construction products as provided for by Council Directive 89/106/EEC (notified under document number C(2005) 1501) (Text with EEA relevance) (2005/403EC) 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 (), and in particular Article 20(2) thereof, Whereas: (1)  Directive 89/106/EEC envisages that in order to take account of the different levels of protection for construction works at national, regional or local level, it may be necessary to establish in interpretative documents classes corresponding to the performance of products in respect of each essential requirement. Those documents have been published as the ‘Communication of the Commission with regard to the interpretative documents of Council Directive 89/106/EEC’ (3). (2)  With respect to the essential requirement of safety in the event of fire, interpretative document No 2 lists a number of interrelated measures which together define the fire safety strategy to be developed in different ways in the Member States. (3) Interpretative document No 2 identifies the requirements for construction products for roofs exposed to an external fire. (4) By way of a harmonised solution, a system of classes was adopted in Commission Decision 2001/671/EC of 1) OJ L 40, 11.2.1989, p. 12.

(® O] C 62, 28.2.1994, p. 1. 21 August 2001 implementing Council Directive 89/106/EEC as regards the classification of external fire performance of roofs and roof coverings (3). (5)  In the case of certain plastisol coated steel roof sheets, it is necessary to use the classification established in Decision 2001/671/EC. (6)  The external fire performance of many construction products andfor materials, within the classification provided for in Decision 2001/671[EC, is well estab- lished and sufficiently well known to fire regulators in Member States with the consequence that they do not require testing for this particular performance charac- teristic. (7)  The measures provided for in this Decision are in accordance with the opinion of the Standing Committee on Construction, HAS ADOPTED THIS DECISION: Article 1 The construction products and/or materials which satisfy all the requirements of the performance characteristic ‘external fire performance’ without need for further testing are set out in the Annex. Article 2 The specific classes to be applied to different construction products and/or materials, within the external fire performance classification adopted in Decision 2001/671/EC, are set out in the Annex to this Decision.
