标准摘要
[中文适用范围]： IEC 60974-8:2021 RLV 包含官方 IEC 国际标准及其红线版本。 Redline 版本仅提供英文版本，为您提供了一种快速、简单的方法来比较官方 IEC 标准与其先前版本之间的所有更改。 IEC 60974-8:2021 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。这些气体控制台旨在为非爆炸性环境中的电弧焊、等离子切割、气刨和相关工艺提供气体。气体控制台可以位于电源外壳的外部或内部。在后一种情况下，电源应满足 IEC 60974-1 和本文件的要求。第三版取消并取代了 2009 年发布的第二版。该版本构成了技术修订版。相对于前一版本的重大技术变化如下： - IEC 60974-1:2017 的发布引起的变化； - IEC 60974-1:2017 第 15 条中对铭牌的要求； ——13.2 中指令的要求。 IEC 60974 的本部分应与 IEC 60974-1 结合使用。 [外文原描述]： IEC 60974-8:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its 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.
