GB/T 17650.1線纜燃燒鹵酸氣體測(cè)定 – 標(biāo)準(zhǔn)名稱
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線纜燃燒鹵酸氣體測(cè)定 – 適用范圍
本標(biāo)準(zhǔn)第1部分規(guī)定的試驗(yàn)方法適用于取自電纜或光纜結(jié)構(gòu)的以鹵化聚合物為基礎(chǔ)的混合物和含鹵添加劑混合物，在燃燒時(shí)釋出的除氫氟酸外的鹵酸氣體總量的測(cè)定。
為了保證試驗(yàn)的準(zhǔn)確性,本試驗(yàn)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(duì)于此類混合物或材料，以及所有鹵酸的相當(dāng)含量小于5 mg/g的混合物或材料，推薦采用GB/T 17650.2規(guī)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.
