标准范围

IEC 60800:2021作为IEC 60800:2021 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60800:2021适用于并规定了电阻加热电缆的要求用于低温应用，例如舒适加热和防止结冰。这些加热电缆和加热电缆组可以包括工厂组装的或现场(工地)组装的单元，并且是根据制造商的说明组装的加热电缆。在等于或小于50 V的电压下供电的裸导体和受保护导体不在本文件的范围内。典型应用包括但不限于:-安装在表面中或表面下的表面加热；-直接加热和储存加热；-屋顶、排水沟、管道等的融雪和防冻。IEC 62395系列[1]规定了工业和商业应用的电阻伴热系统，IEC/IEEE 60079-30系列[2]规定了爆炸性环境应用的电阻伴热系统，矿物绝缘加热电缆也是如此。护套温度超过100℃的应用超出了本文档的范围。

IEC 60800:2021 is available as IEC 60800:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60800:2021 is applicable to, and specifies requirements for resistive heating cables for low temperature applications such as comfort heating and the prevention of ice formation. These heating cables and heating cable sets can comprise either factory assembled or field (work-site) assembled units, and are heating cables assembled in accordance with manufacturer’s instructions. Bare conductors and protected conductors to be supplied at voltages equal to, or less than, 50 V are excluded from the scope of this document.
Typical applications include, but are not limited to:
- surface heating installed in or under surfaces;
- direct and storage heating;
- snow melting and frost protection of roofs, gutters, pipes, etc.
Electrical resistance trace heating systems for industrial and commercial applications are specified in the IEC 62395 series [1] and for explosive atmospheres applications in the IEC/IEEE 60079-30 series [2], as are mineral insulated heating cables. Applications in which the sheath temperature exceeds 100 °C are outside the scope of this document.
