比如EN ISO 14971:2019/A11 2021，这个A11是第11次修订版的意思？但官网上是19版，然后就19/A11了。
A1还能理解，有时候还有A2、A3、甚至A11，是有什么特殊意义吗？
谢谢

标准的修订版本，

Amendment,修订。
还有C开头的Correction，更正。

A11、A12 这种含两位数字的表示EN标准修订版（"European only" amendment），A1、A2、A3 这种只含一位数字的表示ISO/IEC国际标准修订版。
EN标准往往是从ISO/IEC标准转化而来的，而EN和ISO/IEC标准维护却是并行在做的，为表示区分。

参考下面的描述：
The formal document designation for the amendment is EN 60825-1:2014/A11:2021. Amendment A11 is an "European only" amendment to EN 60825-1, i.e. there is no parallel amendment for IEC 60825-1:2014 at the IEC level. This is also the reason why the CENELEC amendment has received the number A11 and not A1, since the amendment designation A1 is reserved for the case of an amendment at the IEC level (which would be developed in parallel also for the European level, a process referred to as parallel voting, i.e. parallel as IEC and as CENELEC document). Due to this "European only" amendment, for the first time since Edition 1 will the European version EN 60825-1 (with amendment A11:2021) not be identical with IEC 60825-1.
