标准范围

IEC/IEEE 60079-30-1:20 15规定了在爆炸性环境中应用的电阻伴热加热器的一般和测试要求，不包括EPL Ga和Da。本标准涵盖包括工厂或现场（工地）组装单元的跟踪加热器，并且可以是已经根据制造商的说明组装和/或端接的串联跟踪加热器、并联跟踪加热器、跟踪加热器垫或跟踪加热器面板。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中定义的环境。附录D和E概述了本标准对那些应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 60079-0的一般要求，表1中所示除外（参见第1条-文件范围）。当本标准的要求与IEC 60079-0的要求相冲突时，以本标准的要求为准。IEC/IEEE 60079-30-1的第一版取消并取代了2007年发布的IEC 60079-30-1的第一版，构成了技术修订。除了对IEC 60079-30-1第一版的一般修订和更新以及与IEEE Std.515的协调之外，该版本相对于上一版还包括以下重大变更:-包括最低温度冲击试验；-在热稳定性测试中添加机械程序；-包括热性能测试以取代热安全要求；-包括利用板夹具进行鞘温度测定的第二程序；-包括紫外线和冷凝测试；-文件要求的修订和大幅扩展；-增加了涵盖第1和第2款要求的附件；-增加了涵盖IEC 60079-0要求适用性的表格；-增加了涵盖示踪加热器产品设计验证方法的附件（以前位于IEC 60079-30-2中）；-该版本与几个国家标准的进一步协调。有关IEC 60079-30-1 1.0版（2007年）和IEC/IEEE 60079-30-1 1.0版（2015年）之间变更的意义，请参见文件前言。关键词:爆炸性环境中使用的电表面加热设备，设备防护等级Gb、Gc、Db、Dc

IEC/IEEE 60079-30-1:2015 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 (refer to Clause 1 - Scope of the document). Where a requirement of this standard conflicts with a requirement of IEC 60079-0, the requirement of this standard takes precedence. This first edition of IEC/IEEE 60079-30-1 cancels and replaces the first edition of IEC 60079-30-1 published in 2007 and constitutes a technical revision. This edition includes the following significant changes, apart from the general revision and updating of the first edition of IEC 60079-30-1 and harmonization with IEEE Std.515, with respect to the previous edition:
- the inclusion of a minimum temperature impact test;
- the addition of a mechanical procedure in the thermal stability test;
- the inclusion of a thermal performance test to replace the thermal safety requirements;
- the inclusion of a second procedure utilizing a plate fixture for sheath temperature determination;
- the inclusion of an ultraviolet and condensation test;
- the revision and significant expansion of documentation requirements;
- the addition of Annexes covering requirements for Divisions 1 and 2;
- the addition of a table covering the applicability of requirements from IEC 60079-0;
- the addition of an Annex covering trace heater product design verification methodology (formerly located in IEC 60079-30-2);
- the further harmonization of this edition with several national standards. Please refer to the Foreword of the document for the significance of changes between IEC 60079-30-1, Edition 1.0 (2007) and IEC/IEEE 60079-30-1, Edition 1.0 (2015). Keywords: electric surface heating equipment used in explosive atmospheres, equipment protection levels Gb, Gc, Db, and Dc
