标准摘要
[中文适用范围]： 本部分 IEC 60974 适用于弧焊工艺的焊接电流返回夹，设计用于无需使用工具即可与工件建立电气连接。 本文件不适用于水下焊接和等离子切割的焊接电流返回夹。 本文件规定了焊接电流返回夹的安全和性能要求。 本文件未规定焊接电缆的要求。 [外文原描述]： IEC 60974-13:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60974-13:2021 is applicable to welding current return clamps for arc welding processes, designed to make an electrical connection to the workpiece without using tools. This document is not applicable to welding current return clamps for underwater welding and plasma cutting. This document specifies safety and performance requirements of welding current return clamps. This document does not specify requirements for welding cables. This second edition cancels and replaces the first edition, published in 2011, and constitutes a technical revision. The significant technical changes with respect to the previous edition are the following: - Modified the title from "Welding clamp" to "Welding current return clamp" and updated the term through the document. - Updated all values of test current in Table 1 corrected to 40 °C. - Updated the reference to EN 50565-1:2014, Electric cables - Guide to use for cables with a rated voltage not exceeding 450/750 V (U0/U) – Part 1: General guidance This part of IEC 60974 is to be used in conjunction with IEC 60974-1 .
