Tri-substituted organostannic compounds such as tributyltin (TBT) compounds and triphenyltin (TPT) compounds shall not be used after 1 July 2010 in articles where the concentration in the article, or part thereof, is greater than the equivalent of 0,1 % by weight of tin.
注意原文,where the concentration in the article, or part thereof,物品或其部分中的浓度,因此,哪怕物品中只有某个部分材质含有的浓度超过规定,即不合格,按均质材料判断。
