标准摘要
[中文适用范围]： IEC 60974 的这一部分规定了与可燃气体或氧气一起使用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供应用于非爆炸性环境中的电弧焊@等离子切割@气刨及相关工艺的气体。气体控制台可以位于电源外壳的外部或内部。在后一种情况下，本标准也适用于电源。注：机械化等离子系统图请参见附录 A。 [外文原描述]： IEC 60974-8:2009 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 significant changes with respect to the previous edition are the following: - removal of intrinsically safe design; - introduction of gas mixing function; - new informative rating plate layout; - induced changes due to publication of IEC 60974-1, edition 3.
