六价铬是一种致癌物质,它在汽车和电子工业中的应用受到欧盟的严格限制。目前,在腐蚀保护层中测定Cr(VI)的分析方法已经颁布实施。本文介绍了可用于上述两个行业的Cr(VI)检测标准──EN 15205和IEC 62321,并讨论了两者的差别。
Hexavalent chromium is a carcinogen and its use in the automotive and electronics industries is severely restricted by the European Union. Currently, analytical methods for the determination of Cr (VI) in corrosion protective coatings have been promulgated. This article describes the Cr (VI) testing standards that are available for both of these industries - EN 15205 and IEC 62321 - and discusses the differences between the two.
