IEC 60974-8:20 21作为IEC 60974-8:20 21 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60974-8:20 21规定了用于可燃气体或氧气的气体控制台的安全和性能要求。这些气体控制台设计用于为非爆炸性环境中的弧焊、等离子切割、气刨和相关工艺提供气体。气体控制台可以在电源外壳的外部或内部。在后一种情况下，电源应同时满足IEC 60974-1和本文件的要求。第三版取消并取代了2009年出版的第二版。本版构成技术修订版。与上一版相比的重大技术变更如下:-IEC 60974-1:20 17的发布引起的变化； -如IEC 60974-1:20 17第15条中对额定值板的要求； -13.2中说明的要求。 IEC 60974的这一部分将与IEC 60974-1一起使用。

IEC 60974-8:2021 is available as IEC 60974-8:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60974-8:2021 specifies safety and performance requirements for gas consoles intended to be used with combustible gases or oxygen. These gas consoles are designed to supply gases for use in arc welding, plasma cutting, gouging and allied processes in non-explosive atmospheres. The gas console can be external or internal to the power source enclosure. In the latter case, the power source shall meet the requirements of both IEC 60974-1 and this document. This third edition cancels and replaces the second edition, published in 2009. This edition constitutes a technical revision. The significant technical changes with respect to the previous edition are the following:
- changes induced by the publication of IEC 60974-1:2017;
- requirements for the rating plate as in IEC 60974-1:2017, Clause 15;
- requirements for the instructions in 13.2.
This part of IEC 60974 is to be used in conjunction with IEC 60974-1.
