标准范围

IEC 60079-28:2015作为IEC 60079-28:2015 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 60079-28:2015规定了用于爆炸性环境的发射光辐射设备的要求、测试和标记。它还涵盖位于爆炸性环境之外或受IEC 60079-0中列出的保护类型保护但产生旨在进入爆炸性环境的光辐射的设备。它涵盖第一组、第二组和第三组，以及EPLs Ga、Gb、Gc、Da、Db、Dc、Ma和Mb。本标准不包括紫外线辐射和爆炸性混合物本身吸收辐射引起的点火。爆炸性吸收剂或含有自身氧化剂的吸收剂以及催化吸收剂也不在本标准的范围之内。第二版取消并取代了2006年出版的第一版，构成了技术修订。有关2.0版和上一版文档之间技术变更的完整列表，请参阅文档前言。关键词:用于爆炸性环境的发射光辐射的设备

IEC 60079-28:2015 is available as IEC 60079-28:2015 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60079-28:2015 specifies the requirements, testing and marking of equipment emitting optical radiation intended for use in explosive atmospheres. It also covers equipment located outside the explosive atmosphere or protected by a Type of Protection listed in IEC 60079-0, but which generates optical radiation that is intended to enter an explosive atmosphere. It covers Groups I, II and III, and EPLs Ga, Gb, Gc, Da, Db, Dc, Ma and Mb. This standard does not cover ignition by ultraviolet radiation and by absorption of the radiation in the explosive mixture itself. Explosive absorbers or absorbers that contain their own oxidizer as well as catalytic absorbers are also outside the scope of this standard. This second edition cancels and replaces the first edition, published in 2006, and constitutes a technical revision. Refer to the Foreword of the document for a complete listing of the technical changes between edition 2.0 and previous edition of the document.Keywords: equipment emitting optical radiation intended for use in explosive atmospheres
