这一新的限制要求企业不再将文本所涵盖的PFCA作为一种物质、混合物和物品在市场上销售，如果其质量浓度超过:

•C9-C14 PFCAs及其盐类的总和：25 ppb (0.025 mg/kg);

•C9-C14 PFCAs相关物的总和：260 ppb (0.260 mg/kg)。

此限制所涵盖的物质列在ECHA网站的问答(Q&A)页面上:

-PFNA (C9-PFCA, CAS No. 375-95-1)及其盐

-PFDA (C10-PFCA, CAS No. 335-76-2)及其盐

-PFUnDA (C11-PFCA, CAS No. 2058-94-8)及其盐

-PFDoDA (C12-PFCA, CAS No. 307-55-1)及其盐

-PFTrDA (C13-PFCA, CAS No 72629-94-8)及其盐

-PFTDA (C14-PFCA, CAS No. 376-06-7)及其盐;

以及根据其结构公式有可能降解或转化为C9-C14全氟羧酸的任何其他与PFCA有关的物质。

草案规定，从2023年7月4日起，对个人防护服(PPE)的“防水或防油纺织品”进行临时豁免。

PFCAs是PFAS(全氟烷基物质和多氟烷基物质)的一个子集，根据ECHA上个月公布的另一项限制草案，成员国也希望在欧洲完全限制其制造和使用。

This new restriction requires companies to no longer place on the market PFCAs covered by the text as a substance, in mixtures as well as in articles if their mass concentration exceeds:

·25 ppb (0.025 mg/kg) total of C9-C14 PFCAs and their salts;

·260 ppb (0.260 mg/kg) in sum of C9-C14 PFCA-related substances.

The substances covered by this restriction are listed on the Questions & Answers (Q&A) page of the ECHA website:

-PFNA (C9-PFCA, CAS No. 375-95-1) and its salts,

-PFDA (C10-PFCA, CAS No. 335-76-2) and its salts,

-PFUnDA (C11-PFCA, CAS No. 2058-94-8) and its salts,

-PFDoDA (C12-PFCA, CAS No. 307-55-1) and its salts,

-PFTrDA (C13-PFCA, CAS No 72629-94-8) and its salts,

-PFTDA (C14-PFCA, CAS No. 376-06-7) and its salts;

As well as any other PFCA-related substances which, according to their structural formulas, have the potential to degrade or transform into C9-C14 perfluorocarboxylic acids.

The text provides for some temporary exemptions for "water-repellent or oil-repellent textiles" for personal protective clothing (PPE), which will only be affected by this restriction from July 4, 2023.

PFCAs are a subset of PFAS (per- and polyfluoroalkyl substances) which Member States also want to completely restrict the manufacture and uses of in Europe under another draft restriction published by ECHA last month.
