IEC 60754-3-2018 取自电缆的材料燃烧时释出气体的试验--第3部分:离子色谱法测定低浓度卤素含量 Test on gases evolved during combustion of materials from cables - Part 3: Measurement of low level of halogen content by ion chromatography

This part of IEC 60754 specifies the apparatus and procedure for the measurement of the amount of halogens evolved during the combustion of materials taken from electric or optical fibre cable constructions.
The method specified in this document is intended for the measurement of the content of chlorine (Cl), bromine (Br), fluorine (F) and iodine (I), by using the analytical technique of ion chromatography for analysing an aqueous solution resulting from the gases evolved during the combustion.
The heating (combustion) procedure in this part of IEC 60754 is the same as in IEC 60754-2.
The method is intended for materials with an individual halogen content not exceeding 10 mg/g.
The method specified in this document is intended for the testing of individual components used in a cable 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 1 The relevant cable standard indicates which components of the cable are tested.
NOTE 2 This test method is sometimes used to test materials to be used in cable manufacture.
For reasons of precision, this method is not recommended for detecting values of halogens less than 0,1 mg/g of the sample taken.dition 1.0 2018-03 INTERNATIONAL STANDARD Test on gases evolved during combustion of materials from cables – Part 3: Measurement of low level of halogen content by ion chromatography IEC 60754-3:2018-03(en) THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 2018 IEC, Geneva, Switzerland All rights reserved.
