+AMD1:2019 CSV 电缆材料燃烧过程中产生气体的试验第1部分:卤素酸气体含量的测定

[中文适用范围]： 本部分IEC 60754规定了用于测定在基于卤化聚合物和含有卤化添加剂的化合物燃烧过程中产生的卤酸气体量（除氢氟酸外）的设备和程序，这些化合物取自电气或光纤电缆结构。 注1：本测试方法不能测定氢氟酸。可在IEC 60684-2中找到合适的方法。 注2：本测试方法可用于测试用于电缆制造的材料，但不应基于此类测试做出电缆性能声明。 注3：相关电缆标准应指明电缆的哪些组件应进行测试。 注4：就本标准而言，术语“电缆”涵盖所有用于传输能量或信号的绝缘金属导体电缆。 本标准中规定的方法旨在用于测试电缆结构中使用的单个组件。使用此方法将能够验证电缆规格中对电缆结构的单个组件所述的要求。 注5：生产商和采购商之间达成协议后，本标准中给出的方法可用于测试代表电缆结构的材料组合，但不应基于此类测试做出符合本标准的电缆性能声明。关于此类方法的信息在附录A中给出。 出于精度原因，不建议使用此方法报告样品中卤酸生成量小于5 mg/g的情况。 [外文原描述]： IEC 60754-1:2011+A1:2019 specifies the apparatus and procedure for the determination 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. The method specified in this standard 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. The significant technical changes with respect to the previous edition are as follows: - improved definition of safety requirements relating to capture of gases and use of reagents; - introduction of guidance on preparation of test specimens for a more even combustion; - improvements to the procedure for establishing the heating regime; - improved expression of tolerances and precision; - definition of the procedure for the blank test; - introduction of an informative annex giving details of a methodology for the determination of the halogen acid gas content of a sample representative of a cable construction. The contents of the corrigendum of November 2013 have been included in this copy. This consolidated version consists of the third edition (2011) and its amendment 1 (2019). Therefore, no need to order amendments in addition to this publication.
