CSA C22.2 No. 21-14 Ninth Edition, Cord sets and power-supply cords标准更新:感谢安规仪器网论坛会员提供资料。安规仪器网提供下载链接:



与之前的版本相比较,C22.2 No. 21-14标准

重新整理了标准,对于不同类型(功能)的延长线,在标准里面有了单独的章节,包括适用标准CAN/CSA-C22.2 No. 60320-1的连接器。
新增以前C22.2 No.21-95(R2009)引用其他标准的要求。

附件2是标准变更部分的概述, 供您参考.
C22.2 No. 21-14标准替代之前的C22.2 No.21-95(R2009)版本并整合了Technical Information Letter (TIL)CSA A-29A,季节性室内室外用的延长线的过渡认证要求。随着C22.2 No. 21-14标准的发布, TIL CSA A-29A将被撤回视作无效。
