GB/T 17650.1 Test on gases evolved during combustion of materials from cables Part 1: Determination of the amount of halogen acid gas
GB/T 17650.1 取自电缆或光缆的材料燃烧时释出气体的试验方法第1部分:卤酸气体总量的测定

GB/T 17650.1线缆燃烧卤酸气体测定 – 适用范围
本标准第1部分规定的试验方法适用于取自电缆或光缆结构的以卤化聚合物为基础的混合物和含卤添加剂混合物，在燃烧时释出的除氢氟酸外的卤酸气体总量的测定。

为了保证试验的准确性,本试验方法不适用于释出卤酸量小于5mg/g的样品。本方法不能用来确定混合物或材料为“无卤”。对于此类混合物或材料，以及所有卤酸的相当含量小于5 mg/g的混合物或材料，推荐采用GB/T 17650.2规定的方法。

The test method specified in Part 1 of this standard is applicable to the total amount of halogen acid gas other than hydrofluoric acid released during combustion of the halogenated polymer-based mixture and halogen-containing additive mixture taken from the cable or optical cable structure Determination.

In order to ensure the accuracy of the test, this test method is not suitable for samples with a halogen acid release of less than 5mg / g. This method cannot be used to determine that a mixture or material is “halogen-free.” For such mixtures or materials, as well as all mixtures or materials with a halogen acid equivalent content of less than 5 mg / g, the method specified in GB / T 17650.2 is recommended.
