8、 Std 515-2004, IEEE Standard for the Testing, Design, Installation, and Mainte- nance of Electrical Resistance Heat Tracing for Industrial Applications.) The scope of this standard includes specific testing requirements for qualifying electrical resistance heating cables and heating devices for use
9、in industrial applications, as well as a basis for electrical and thermal design. Applications include unclassified, and both North American Division and Zone classified areas. This document was first published as a recommended practice in 1983. In 1989, it was elevated to a stan- dard, and added Di
10、vision 1 heating cables. In 1997, standard was expanded to include American classified zone heaters. A 32-week long benchmark test was added to provide a thermal shock cycling test. This test established a minimum performance criteria for new products and offered a system validate product temperatur
11、e ratings claimed by manufacturers, and provided a minimum acceptable level of quality/performance by the heating devices.

30、ical Resistance Heat Tracing for Industrial Applications 1. Overview 1.1 Scope This standard provides requirements for the testing, design, installation, and maintenance of electrical resistance heat tracing in general industries as applied to pipelines, vessels, pretraced and thermally insulated in
31、strument tubing and piping, and mechanical equipment. The electrical resistance heat tracing is in the form of series heating cables, parallel heating cables, and surface heating devices. In this standard, the terms hazardous (classified) locations and potentially flammable atmospheres refer to the
32、same conditions. The requirements also include test criteria to determine the suitability of these heating devices utilized in industrial applications as applied in unclassified (ordinary) and hazardous (classified) locations as follows: Class I 1 Division 1 Division 2 Zone 1 Zone 2 Class II Divisio
33、n 1 Division 2 Class III Division 1 Division 2 Unclassified (ordinary) 1 Class I is a term used with zone locations in the USA and Canada.

All rights reserved. 1.2 Purpose The provisions of this standard should ensure that pr
35、ocess, fluid, or material temperatures are maintained and provide electrical, thermal, and mechanical durability to the heat-tracing system, such that in normal use its performance is reliable and poses no danger to the user or surroundings. This standard is to serve as a complementary standard to t
36、hose national and international standards addressing electrical resistance heat tracing, such as the following: NFPA 70-2002, National Electrical Code , NEC , Article 427. EN 50019-2000 B8. 2 IEC 62086-1:2001 B18. IEC 62086-2:2001 B19. IEC 60079-0:2004 B14. IEC 60079-7:2001 B16. 2. References This s
