标准范围

IEC 62822-3:20 23适用于专为专业人员和外行使用而设计的电阻焊和相关工艺设备。更一般地，本文件涵盖焊接电流在其几何形状不能改变的电路中流动的设备，并且与电流发生器的技术无关(例如用于点焊或缝焊的LF-AC、MF-DC或用于螺柱焊接的电容放电)。这第二版取消并取代了2017年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)将不确定性纳入评估结果；b)简化暴露评估方法。

IEC 62822-3:2023 applies to equipment for resistance welding and allied processes designed for occupational use by professionals and for use by laymen.
More generally, this document covers equipment for which the welding current flows in an electrical circuit whose geometry cannot be changed and regardless of the technology of the current generator (for example LF-AC, MF-DC for spot or seam welding or capacitive discharge used for stud welding).
This second edition cancels and replaces the first edition published in 2017. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) inclusion of the uncertainties in the results of the assessment;
b) simplification of the methods of exposure assessment.
