BS EN 13501-6:2014EN 13501-6:2014 (E) 5 Introduction The aim of

29、 this European Standard is to define a harmonized procedure for the classification of reaction to fire of electric cables. This classification is based on the test procedures listed in Clause 5. This European Standard has been prepared in support of the second essential requirement in the EC Constru

30、ction Products Regulation (EU) N305/2011 and as detailed in the Interpretative Document Number 2: Safety in case of fire (OJ C62 Vol. 37). Background information on the Commission Decision regarding the classification of the reaction to fire performance of electric cables is given in Annex B. There

31、is a procedure by which certain products can be assigned a particular fire classification without the need for testing. Such products have well established reaction to fire performance and have been agreed by the Standing Committee on Construction. Agreements relating to such products which may be c

32、lassified without further testing (CWFT) are published in the Official Journal of the EC and are listed on the Nando-CPD database on the EC website (http:/europa.eu.int/comm/enterprise/construction). Part 1 of this European Standard covers classification resulting from reaction to fire tests for pro

33、ducts other than electric cables. Parts 2, 3 and 4 of this European Standard are concerned with classification resulting from fire resistance tests. Part 5 covers classification resulting from tests for external fire exposure to roofs. BS EN 13501-6:2014EN 13501-6:2014 (E) 6 1 Scope This European St

34、andard provides the reaction to fire classification procedure for electric cables. NOTE For the purpose of this European Standard the term “electric cables” covers all power, control and communication cables, including optical fibre cables. 2 Normative references The following documents, in whole or
