IEEE 515.1-2022

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.
