标准范围

IEC TS 60079-46:2017(E)规定了由设备组件制造商负责的爆炸性环境中使用的设备组件的设计、构造、组装、测试、检查、标记、记录和评估的要求。本文件的要求适用于根据IEC 60079系列或ISO 80079系列组成组件并具有单独证书的单个项目。然后，这些单独的项目被集成为设备组件的一部分。还包括解决组件的方面的要求，这些方面可能超出了形成组件的单个项目的证书。本文件的范围包括评估危险区域装配的附加要求，不包括非危险区域装配的要求危险区域。假设除本文件要求外，同一方或不同方将验证是否符合适用于非危险区域的其他电气或机械要求。本文件不适用于:-完全被一种或多种IEC 60079和ISO 80079设备类型保护覆盖的设备；-根据IEC 60079-13的加压室“p”，根据IEC TR 60079-16的用于保护分析仪外壳的人工通风，以及针对特定Ex组件的其他标准；-在IEC 60079-14范围内的最终用户现场安装；-危险区域的分类；-用于易受火灾潮湿影响的地雷的设备组件（第一类应用）；-爆炸物或自燃物质产生的固有爆炸性情况和粉尘（例如爆炸物制造和加工）；-用于医疗目的的房间；-易燃薄雾造成危险的区域的电气装置。本规范仅旨在为组件的初始供应提供验证。关键词:爆炸性环境中使用的设备组件

IEC TS 60079-46:2017(E) specifies requirements for the design, construction, assembly, testing, inspection, marking, documenting and assessment of equipment assemblies for use in explosive atmospheres under the responsibility of the manufacturer of the equipment assembly. The requirements of this document apply to individual items according to the IEC 60079 series or ISO 80079 series that comprise the assembly and that have individual certificates. These individual items are then integrated as part of the equipment assembly. Also included are requirements to address aspects for the assembly which may be beyond the certificates of the individual items forming the assembly. The scope of this document includes assessment of the additional requirements for assemblies for hazardous areas and does not include requirements for non-hazardous areas. It is assumed that compliance with other electrical or mechanical requirements that are applicable for non-hazardous areas will be verified by either the same or different party in addition to the requirements of this document. This document does not apply to:
- equipment which is covered, in its entirety, by one or more IEC 60079 and ISO 80079 equipment types of protection;
- pressurized rooms, “p”, in accordance with IEC 60079-13, artificial ventilation for the protection of analyzer(s) houses in accordance with IEC TR 60079-16, and other standards addressing specific Ex assemblies;
- installation at the end-user site under the scope of IEC 60079-14;
- classification of the hazardous area;
- equipment assemblies for mines susceptible to firedamp (Group I applications);
- inherently explosive situations and dust from explosives or pyrophoric substances (for example explosives manufacturing and processing);
- rooms used for medical purposes;
- electrical installations in areas where the hazard is due to flammable mist.
The specification is only intended to provide validation for the initial supply of an assembly.
