IEEE 515.1-1995

This recommended practice provides detailed recommendations for the testing, design, installation, and maintenance of electrical resistance heat tracing in commercial applications. Commercial applications include installations inside and outside of commercial business buildings, such as office buildings, hospitals, and airports. Typical applications include freeze 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 . The recommendation also include test criteria to determine the suitability of heating cables and fittings that are utilized for these applications. Commercial applications involving hazardous (classified) locations should meet the requirements in IEEE Std 515-1989 in addition to the requirements in this document.

The provisions of this recommended practice should ensure that adequate material temperatures are maintained, and that electrical, thermal, mechanical, and water-exclusion durability are provided to the heat tracing system. In addition, it should provide that under normal use the products will exhibit long term performance reliability without damage to the user or surroundings. This recommended practice is a supplement to those provisions outlined in ANSI/NFPA 70-1993, Articles 426 and 427.

New IEEE Standard - Superseded. Specific test requirements for qualifying electrical resistance heating cables for commercial service and a basis for electrical and thermal design are provided. Heater characteristics are addressed and installation and maintenance requirements are detailed. Recommendations and requirements for unclassified heating cable applications are provided.
