附件XVII第19条第4b)款列出了经CCA C型处理过的木材的用途。经处理的木材可以用于其他用途吗？例如，除地铁枕木外，还可以用于铁路枕木。

附件XVII第19条第4b)款列出了经CCA C型处理过的木材的用途。经处理的木材可以用于其他用途吗？例如，除地铁枕木外，还可以用于铁路枕木。

Under Entry 19, paragraph 4b) of Annex XVII there is a list of applications for which wood treated with CCA type C can be used. May treated wood be used for other applications, such as railway sleepers other than underground railway sleepers?

REACH 附件 XVII 中关于砷化合物的第 4b) 款列出了经 CCA 处理过的木材的一系列用途。这并非可能用途的示例清单，而是一份授权用途的详尽清单。这既源于这些条款的实际措辞，也源于其目的，即第 4 款中规定的例外情况必须经过严格的解释，这一点已得到欧洲法院的确认（案件编号 C-358/11，第 40-43 页）。因此，经 CCA 处理过的木材不得用于第 4b) 款所列用途以外的其他用途。因此，经 CCA 处理过的木材不能用于地面铺设的铁路枕木。

Paragraph 4b) of Annex XVII to REACH concerning arsenic compounds provides for a list of applications for which wood treated with CCA may be used. This is not a list of examples of possible uses but an exhaustive list of authorised applications. It flows both from the actual wording of those provisions and from their objective that the derogation provided for in paragraph 4 must necessarily be subject to a strict interpretation, as confirmed by the Court of Justice (case C-358/11, pp. 40-43). Consequently, wood treated with CCA cannot be used for other applications than the ones listed in paragraph 4 b). Wood treated with CCA can, therefore, not be used for railway sleepers installed above ground.
