REACh 附件十七镍释放禁令法规原文: in articles referred to in point (b) where these have a non-nickel coating unless such coating is sufficient to ensure that the rate of nickel release from those parts of such articles coming into direct and prolonged contact with the skin will not exceed 0,5 μg/cm 2 / week for a period of at least two years of normal use of the article. 对于有非镍镀层的，必须保证在两年正常使用的情况下，(在镀层的保护下)仍然能满足限值要求 所以EN 12472的使用前提是针对非镍镀层。 若是含镍镀层的话，肯定是需要做镀层的镍释放的。
