EN 13501 Fire classification of construction products and building elements consists of the following parts: Part 1: Classifi

27、cation 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 products and elements used in building service installations: fire resisting ducts and fire dam

DINEN 13501-6:2014-07EN 13501-6:2014(E)5 Introduction The aim of this European Standard is to define a harmonized proced

31、ure 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 Construction Products Regulation (EU) N305/2011 and as detailed

32、 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 is a procedure by which certain products can be assigned

33、 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 classified without further testing (CWFT) are published i

34、n 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 products other than electric cables. Parts 2, 3 and 4 of th

35、is European Standard are concerned with classification resulting from fire resistance tests. Part 5 covers classification resulting from tests for external fire exposure to roofs. DINEN 13501-6:2014-07EN 13501-6:2014 (E) 6 1 Scope This European Standard provides the reaction to fire classification p

36、rocedure 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 in part, are normatively referenced in this document
