根据 REACH 附件 XVII 第 23 条第 10 款规定，如果珠宝首饰金属部件中镉的含量等于或大于金属重量的 0.01%，则不得使用或投放市场。此浓度阈值适用于珠宝首饰的每个金属部件，还是适用于整个珠宝首饰？

根据 REACH 附件 XVII 第 23 条第 10 款规定，如果珠宝首饰金属部件中镉的含量等于或大于金属重量的 0.01%，则不得使用或投放市场。此浓度阈值适用于珠宝首饰的每个金属部件，还是适用于整个珠宝首饰？

According to paragraph 10 of entry 23 of Annex XVII to REACH cadmium shall not be used or placed on the market if the concentration is equal to or greater than 0,01% by weight of the metal in metal parts of jewellery. Does this concentration threshold apply to each metal component of an item of jewellery or to the jewellery item as a whole?

根据欧盟委员会法规 (EU) 494/2011 附件第 10 段（修订 REACH 法规附件 XVII 第 23 条，即镉），镉的浓度阈值适用于珠宝首饰的每个金属部件。立法者使用的措辞，即“珠宝首饰和仿制珠宝的金属部件”，暗示每个金属部件都与镉相关；因此，为了确定该限制是否适用，在这种情况下，必须针对每个金属部件计算浓度。因此，如果珠宝首饰内部（金属）部件表面有多层金属涂层，则应将这些金属涂层视为金属部件的组成部分，并针对整个金属部件计算 0.01% 的浓度限值。如果珠宝首饰内部部件不是金属，但涂层由金属层构成，则该涂层被视为一个金属部件。如果珠宝首饰包含多个金属部件，则每个金属部件都应符合浓度限值。

With reference to paragraph 10 of the Annex to Commission Regulation (EU) 494/2011 amending entry 23 of Annex XVII of the REACH Regulation (cadmium) the concentration threshold of cadmium applies in each metal part of jewellery. The wording used by the legislator, i.e. "metal parts of the jewellery and imitation jewellery" implies that each metal part is relevant; therefore in order to determine if the restriction applies the calculation of the concentration in this case is to be done for each metal part. Therefore, if there are several metal layers as coatings on the surface of an inner (metallic) part of the jewellery these should be regarded as integral part of the metal part and the concentration limit of 0,01% is calculated for this whole metal part. In case the inner part is not metal, but the coating is made of metal layers, this coating is regarded as one metal part. If the jewellery article contains several metal parts, each of them should comply with the concentration limit.
