GB/T 22930-2008 in English

《GB/T 22930-2008皮革和毛皮 化学试验 重金属含量的测定》由TC252（全国皮革工业标准化技术委员会）归口，主管部门为中国轻工业联合会。
本标准规定了皮革、毛皮中铅（Pb）、镉（Cd）、镍（Ni）、铬（Cr）、钴（Co）、铜（Cu）、锑（Sb）、砷（As）、汞（Hg）九种元素的总量和可萃取量的测定方法。
本标准适用于各类皮革、毛皮及其制品。

1 Scope

This standard specifies the method for determining the total content and extractable content of nine elements - lead (Pb), cadmium (Cd), nickel (Ni), chromium (Cr), cobalt (Co), copper (Cu), stibium (Sb), arsenic (As) and mercury (Hg) - in the leather and fur.
This standard is applicable to various leathers, furs and their derived products.
