标准摘要
[中文适用范围]： IEC/IEEE 60079-30-1:2025 以 IEC/IEEE 60079-30-1:2025 RLV 的形式发布，其中包含国际标准及其红线版本，展示了与上一版相比技术内容的所有变更。IEC/IEEE 60079-30-1:2025 规定了在爆炸性大气中使用的电热跟踪加热器的一般要求和测试要求，但不包括设备保护等级（EPL）为 Ga、Da、Ma 和 Mb 的设备。本文件涵盖的跟踪加热器包括工厂或现场（工地）组装的单元，且可以是串联跟踪加热器、并联跟踪加热器、跟踪加热垫或根据制造商说明组装和/或终端的跟踪加热板。本文件还包括与跟踪加热系统一起使用的终端组件和控制方法的要求。本文件所指的爆炸性大气是 IEC 60079-10-1 和 IEC 60079-10-2 中定义的。附录 F 和附录 G 概述了本文件对采用分区方法进行区域分类的用户的应用。IEC/IEEE 60079-30-1 的第二版取消并替代了 2015 年发布的第一版。本版为技术修订版。与前一版相比的重大技术变更可在本出版物的前言中找到。 [外文原描述]： IEC/IEEE 60079-30-1:2025 is available as IEC/IEEE 60079-30-1:2025 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC/IEEE 60079-30-1:2025 specifies general and testing requirements for electrical resistance trace heaters for application in explosive atmospheres with the exclusion of those for Equipment Protection Levels (EPL) Ga, Da, Ma and Mb equipment. This document covers trace heaters that comprise either factory or field (worksite) assembled units, and which can be series trace heaters, parallel trace heaters, trace heater pads, or trace heater panels that have been assembled and/or terminated in accordance with the manufacturer's instructions. This document also includes requirements for termination assemblies and control methods used with trace heating systems. The explosive atmospheres referred to in this document are those defined in IEC 60079-10-1 and IEC 60079-10-2. Annex F and Annex G outline the application of this document for those users applying the Division method of area classification This second edition of IEC/IEEE 60079-30-1 cancels and replaces the first edition of IEC/IEEE 60079-30-1 published in 2015. This edition constitutes a technical revision. The significant technical changes with respect to the previous edition can be found n the foreword of this publication.
