GB/T 17650.1 取自電纜或光纜的材料燃燒時釋出氣體的試驗方法第1部分:鹵酸氣體總量的測定

GB/T 17650.1線纜燃燒鹵酸氣體測定 – 適用范圍
本標準第1部分規定的試驗方法適用于取自電纜或光纜結構的以鹵化聚合物為基礎的混合物和含鹵添加劑混合物，在燃燒時釋出的除氫氟酸外的鹵酸氣體總量的測定。

為了保證試驗的準確性,本試驗方法不適用于釋出鹵酸量小于5mg/g的樣品。本方法不能用來確定混合物或材料為“無鹵”。對于此類混合物或材料，以及所有鹵酸的相當含量小于5 mg/g的混合物或材料，推薦采用GB/T 17650.2規定的方法。

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.
