BS EN 60754-1:201460754-1 IEC:2011 7 TEST ON GASES EVOLVED DURING COMBUSTION OF MATERIALS FROM CABLES Part 1: Determination of the halogen acid gas content 1 Scope This part of IEC 60754 specifies the apparatus and procedure for the dete

41、rmination of the amount of halogen acid gas, other than hydrofluoric acid, evolved during the combustion of compounds based on halogenated polymers and compounds containing halogenated additives taken from electric or optical fibre cable constructions. NOTE 1 This test method is not able to determin

42、e hydrofluoric acid. A suitable method may be found in IEC 60684-2. NOTE 2 This test method may be used to test materials to be used in cable manufacture, but a declaration of cable performance should not be made based on such a test. NOTE 3 The relevant cable standard should indicate which componen

43、ts of the cable should be tested. NOTE 4 For the purposes of this standard, the term “electric cable” covers all insulated metallic conductor cables used for the conveyance of energy or signals. The method specified in this standard is intended for the testing of individual components used in a cabl

44、e construction. The use of this method will enable the verification of requirements which are stated in the appropriate cable specification for individual components of a cable construction. NOTE 5 By agreement between the producer and purchaser, the methodology given in this standard may be used to

45、 test combinations of materials representing a cable construction, but a declaration of cable performance to this standard should not be made based on such a test. Information on such a method is given in Annex A. For reasons of precision this method is not recommended for reporting values of haloge
