标准范围

IEC 60974-4:20 16规定了定期检查和维修后确保电气安全的测试程序。这些测试程序也适用于维护。本标准适用于根据IEC 60974-1或IEC 60974-6设计的弧焊及相关工艺用电源。按照IEC 60974其他部分设计的独立辅助设备，可以按照IEC 60974本部分的相关要求进行测试。这第三版取消并取代了2010年出版的第二版。它构成技术修订。与上一版相比，主要的重大技术变化如下:-关于基本标准，术语“泄漏电流”已被“接触电流”和“保护导体电流”取代。-以非电流方式连接的电路的测量应根据制造商的信息进行测试。-涉及要进行的测量的章节顺序已更改。-附录B中的示例测试报告已被修改。

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- With regard to basic standards the term "leakage current" has been replaced by "touch current" and "protective conductor current".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.
