标准范围

IEC/IEEE 60079-30-2:20 15（E）为在可能存在爆炸性环境的区域中应用电阻伴热系统提供了指南，不包括那些被归类为需要EPL Ga/Da的区域（分别与0区和20区的传统关系）。本标准还为爆炸性环境提供了指导，纳入了本标准的一些用户可能应用的区域分类的划分方法。它为伴热系统（包括相关控制和监测设备）的设计、安装、维护和修理提供了建议。它不包括通过感应加热、集肤效应加热或直接管道加热操作的设备，也不包括用于缓解应力的设备。这第一版IEC/IEEE 60079-30-2取消并取代2007年发布的IEC 60079-30-2第一版，构成技术修订。除了对IEC 60079-30-2第一版（与IEEE Std.515相协调）的一般审查和更新之外，该版本还包括以下重大变更:-将示踪加热器产品设计方法和要求重新定位至IEC/IEEE 60079-30-1；-根据SC31J将有关安装、维护和修理的信息重新定位和/或复制到MTs，以便将其添加到IEC 60079-14、IEC 60079-17和IEC 60079-19中；-列入关于安全淋浴和洗眼装置的更详细资料；-引入IEEE标准515的附件。IEC 60079-30-2，1.0版(2007)和IEC/IEEE 60079-30-2，1.0版(2014)。关键词:电阻伴热系统，面积分类的划分方法

IEC/IEEE 60079-30-2:2015(E) provides guidance for the application of electrical resistance trace heating systems in areas where explosive atmospheres may be present, with the exclusion of those classified as requiring EPL Ga/Da (traditional relationship to Zone 0 and Zone 20 respectively). This standard also provides guidance for explosive atmospheres incorporating the Division method of area classification that may be applied by some users of this standard. It provides recommendations for the design, installation, maintenance and repair of trace heating systems including associated control and monitoring equipment. It does not cover devices that operate by induction heating, skin effect heating or direct pipeline heating, nor those intended for stress relieving. This first edition of IEC/IEEE 60079-30-2 cancels and replaces the first edition of IEC 60079-30-2 published in 2007 and constitutes a technical revision. This edition includes the following significant changes, apart from a general review and updating of the first edition of IEC 60079-30-2, harmonization with IEEE Std.515, with respect to the previous edition:
- the relocation of trace heater product design methodology and requirements to IEC/IEEE 60079-30-1;
- the relocation and/or duplication of information on installation, maintenance, and repair to the MTs under SC31J for their addition into IEC 60079-14, IEC 60079-17, and IEC 60079-19;
- the inclusion of more detailed information on safety showers and eyewash units;
- the introduction of Annexes from IEEE Std. 515. Please refer to the Foreword of the document for the significance of changes between IEC 60079-30-2, Edition 1.0 (2007) and IEC/IEEE 60079-30-2, Edition 1.0 (2014).Keywords: electrical resistance trace heating systems, Division method of area classification
