标准摘要
[中文适用范围]： IEC 60974 的这一部分规定了定期检查和维修后的测试程序，以确保电气安全。这些测试程序也适用于维护。本标准适用于按照 IEC 60974-1 或 IEC 60974-6 设计的电弧焊及相关工艺电源。按照IEC 60974其他部分设计的独立辅助设备可按照IEC 60974本部分的相关要求进行测试。 注1：焊接电源可与安装的任何可能影响测试结果的辅助设备一起进行测试。本标准不适用于新型电源或发动机驱动电源的测试。注 2：对于未按照 IEC 60974-1@ 制造的电源，请参阅附录 C。 [外文原描述]： IEC 60974-4:2016 specifies test procedures for periodic inspection and, after repair, to ensure electrical safety. These test procedures are also applicable for maintenance. This standard is applicable to power sources for arc welding and allied processes designed in accordance with IEC 60974-1 or IEC 60974-6. Stand-alone ancillary equipment designed in accordance with other parts of IEC 60974 may be tested in accordance with relevant requirements of this part of IEC 60974. This third edition cancels and replaces the second edition published in 2010. It constitutes a technical revision. The main significant technical changes with respect to the previous edition are the following: - With regard to basic standards the term "leakage current" has been replaced by "touch current" and "protective conductor current". - Measurements of circuits connected in a non-galvanic way shall be tested according to the information of the manufacturer. - The order of the chapters dealing with measurements to be carried out has been changed. - The example test report in Annex B has been adapted.
