IEC 60079的本部分规定了爆炸性环境中使用的电阻跟踪加热器的一般要求和试验要求，EPL Ga和Da除外。本标准涵盖由工厂或现场（工作现场）组装单元组成的跟踪加热器，这些跟踪加热器可以是串联跟踪加热器、并联跟踪加热器、跟踪加热器垫或跟踪加热器面板，它们已按照制造商的要求进行组装和/或端接？这是我的指示。 本标准还包括与伴热系统一起使用的终端组件和控制方法的要求。本标准中提及的爆炸性环境是指IEC 60079-10-1和IEC 60079-10-2中定义的爆炸性环境。 附录D和E概述了本标准对采用区域分类划分方法的用户的应用。 本标准补充和修改了IEC 60079的一般要求- 0，表1所示除外。如果本标准的要求与IEC 60079-0的要求冲突，则以本标准的要求为准。

This part of IEC 60079 specifies general and testing requirements for electrical resistance trace heaters for application in explosive atmospheres with the exclusion of those for EPL Ga and Da. This standard covers trace heaters that comprise either factory or field (work-site) assembled units, and which may 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 standard also includes requirements for termination assemblies and control methods used with trace heating systems. The explosive atmospheres referred to in this standard are those defined in IEC 60079-10-1 and IEC 60079-10-2. Annexes D and E outline the application of this standard for those users applying the Division method of area classification. This standard supplements and modifies the general requirements of IEC 60079-0, except as indicated in Table 1. Where a requirement of this standard conflicts with a requirement of IEC 60079-0, the requirement of this standard takes precedence.
