标准摘要
[中文适用范围]： 本文件规定了测定多氯联苯（PCB）总含量的方法，检查颜料材料中所有 209 种可能的同系物。 本文件适用的工作范围为 1 mg/kg 至 150 mg/kg。 该方法的定量下限为每个同系物 1 mg/kg。 低于 1 mg/kg 的结果仅被认为是定性的。 [外文原描述]： This document specifies a method for determining the total content of polychlorinated biphenyls (PCBs), checking for all 209 possible congeners in pigment materials. This document is applicable to a working range from1 mg/kg to 150 mg/kg. The lower quantitation limit of this method is 1 mg/kg per congener. Results below 1 mg/kg are considered to be qualitative only.
