EN 50267-2-1鹵素酸性氣體含量測試 – 適用范圍
EN 50267-2-1規定了在以鹵化聚合物為基礎的化合物和含鹵化添加劑的化合物(取自電纜結構)燃燒過程中產生的除氫氟酸以外的鹵代酸氣體量的測定方法。這種方法不適用于定義“零鹵素”或“無鹵素”的化合物或材料。對于此類化合物或材料，以及所有化合物或材料中所含的鹵素酸當量均小于5mg/g，建議使用EN50267-2-2中規定的標準。
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.
