本标准提供了测试标准，以确定用于商业应用的加热装置和配件的适用性。该标准还包括这些应用中电阻跟踪加热的设计、安装和维护的详细建议。商业应用包括商业建筑内外的装置，如办公楼、医院和机场。典型应用包括水管防冻； 热水管道和其他管道的温度维护；洒水系统的保护；屋顶、排水沟和路面除冰；以及4.1中表1所示的其他应用。对于涉及危险（分类）场所的商业应用，请参考IEC/IEEE 60079-30-1以及任何其他适用规范和标准。

This standard provides test criteria to determine the suitability of heating devices and fittings that are used for commercial applications. The standard also includes detailed recommendations for the design, installation, and maintenance of electrical resistance trace heating in these applications. Commercial applications include installations both inside and outside commercial business buildings, such as office buildings, hospitals, and airports. Typical applications include freeze protection of water pipes; temperature maintenance of hot water piping and other lines and tubing; protection of sprinkler systems; roof, gutter, and pavement deicing; and other applications as shown in Table 1. For commercial applications involving hazardous (classified) locations, refer to IEC/IEEE Std 60079-30-1 and IEC/IEEE Std 60079-30-2 as well as any other applicable codes and standards.
