授权要求是否适用于附件 XIV 中作为另一种物质或混合物中的杂质存在的物质？

Does the authorisation requirement apply to a substance in Annex XIV that is present as an impurity in another substance or mixture?

授权要求适用于附件XIV所列物质的单独投放市场和使用。因此，如果附件XIV中的物质仅仅是另一种物质的杂质、添加剂或成分，则通常不适用授权要求，除非附件XIV条目中另有规定（例如，物质W以及物质X、Y和Z，其中W的浓度≥x%），或该物质也列在附件XIV中。如果附件XIV中所列物质作为混合物的成分，则授权要求适用于此用途（即混合物的配方）。此外，除非附件XIV中的物质在混合物中的含量低于REACH第56(6)条规定的浓度限值，否则此类混合物的投放市场和使用都需要授权。另请参阅：REACH物质识别和命名指南（链接：http://echa.europa.eu/documents/10162/13643/substance_id_en.pdf）。

The authorisation requirement applies to the placing on the market and use of a substance on its own as listed in Annex XIV. Therefore, it usually does not apply if the Annex XIV substance is only an impurity or additive or constituent of another substance, unless this is specified in the Annex XIV entry (e.g. substance W and substances X, Y and Z containing substance W in a concentration ≥ x %) or the other substance is also listed in Annex XIV.If a substance listed in Annex XIV is included as a component in a mixture, the authorisation requirement applies for this use (i.e. the formulation of the mixture). Further, the placing on the market and use of such mixtures require authorisation, unless the Annex XIV substance is present in the mixture below the concentration limits set out in REACH Article 56(6).
