18、 (EN 13501-5:2005) has been prepared by Technical Committee CEN/TC 127 “Fire safety in buildings”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 200
19、6, and conflicting national standards shall be withdrawn at the latest by June 2006. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of the Construction Products Directive. C
20、EN, CENELEC and EOTA committees preparing technical specifications which contain performance requirements against external fire exposure of roofs should make reference to the classification given in this European Standard and not refer directly to any specific fire test method. EN 13501 consists of
21、the following parts: Part 1: Classification using data from reaction to fire tests, Part 2: Classification using data from fire resistance tests, excluding ventilation services, Part 3: Classification using data from fire resistance tests on components of normal building service installations: fire
22、resisting ducts and fire dampers Part 4: Classification using data from fire resistance tests on components of smoke control systems, Part 5: Classification using data from external fire exposure to roof tests. According to the CEN/CENELEC Internal Regulations, the national standards organizations o
23、f the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Sp

25、sification of roofs/roof coverings exposed to external fire. This classification is based on the test methods listed in Clause 5. This European Standard has been prepared in support of the second essential requirement in the EC Construction Products Directive (89/106/EEC) and as detailed in the Inte
26、rpretative Document Number 2: Safety in case of fire (OJ C62 Vol. 37). The European Commission has drawn up a list of products which, under specified conditions, may be considered to be Class BROOF without testing. This information is given in the Commission Decision of 2000-09-06 establishing the l
27、ist of products belonging to Classes BROOF (Decision 2000/553/EC).

28、on procedures for roofs/roof coverings exposed to external fire based on the four test methods given in ENV 1187:2002. For the classification of a roof/roof covering, only those test methods need to be applied for which the corresponding classification is envisaged. Products are considered in relati

NOTE The distinction between roofs with a steep slope and facades, in terms of the test and classification standard to be applied, may be subject to national regulations.
