EN 50267-2-1卤素酸性气体含量测试 – 适用范围

EN 50267-2-1规定了在以卤化聚合物为基础的化合物和含卤化添加剂的化合物(取自电缆结构)燃烧过程中产生的除氢氟酸以外的卤代酸气体量的测定方法。这种方法不适用于定义“零卤素”或“无卤素”的化合物或材料。对于此类化合物或材料，以及所有化合物或材料中所含的卤素酸当量均小于5mg/g，建议使用EN50267-2-2中规定的标准。

Scope:
EN 50267-2-1 Specifies the 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 cable construction.

For reason of accuracy this method is not recommended for use where the amount of halogen acid evolved is less than 5mg/g of the sample taken. This method is not suitable for defining compounds or materials described as”zero-halogen” or “halogen-free”. For such compounds or materials, and all compounds or materials contains less than 5mg/g halogen acid equivalent, it is recommended to use specified in EN50267-2-2.
