EN 12472是针对有涂层样品的前处理方法(腐蚀磨损),EN 1811是用人工汗液萃取、测试,也就是说有涂层的:EN 12472 + EN 1811,而没有涂层的:EN 1811. 测试的时候使用参考样,结果达到偏差范围就没问题了。按标准(EN 1811)要求做:Articles with non-nickel containing surface coatings that come into direct and prolonged contact with the skin shall be tested according to EN 12472, followed by this standard.
