标准范围

IEC 60754-3:20 18（E）规定了测量取自电缆或光纤电缆结构的材料燃烧过程中析出的卤素量的设备和程序。本文件中规定的方法旨在通过使用离子色谱法的分析技术来分析由燃烧过程中放出的气体产生的水溶液来测量氯（Cl）、溴（Br）、氟（F）和碘（I）的含量。IEC 60754这一部分中的加热（燃烧）程序与IEC 60754-2中的相同。该方法适用于单个卤素含量不超过10mg/g的材料。本文件中规定的方法旨在测试电缆结构中使用的单个组件。该方法的使用将能够验证在适当的电缆规范中针对电缆结构的各个部件所规定的要求。出于精密度的原因，不建议该方法用于检测小于0.1 mg/g样品的卤素值。

IEC 60754-3:2018(E) 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.
For reasons of precision, this method is not recommended for detecting values of halogens less than 0,1 mg/g of the sample taken.
