26、istance Trace Heating for Commercial Applications. The utilization of electrical resistance trace heating in the commercial construction industry has increased steadily due to the availability of more reliable products and more efficient operation. The need exists for broad-based technical informati
27、on about electrical resistance trace heating systems. In the construction industry, these systems are used for temperature maintenance of domestic hot water, general freeze protection of piping and drain lines, roof and gutter deicing, snow melting of concrete and asphalt embankments, frost heave pr
28、otection of freezer floors in cold storage warehouses, and floor warming as an enhancement for the comfort of office personnel. The approval process for these systems provides the basis for this standard. This standard provides specific test requirements for qualifying electrical resistance heating
29、devices for commercial construction and a basis for electrical and thermal design. Type and routine production tests are outlined in this standard and address such subjects as mechanical durability, resistance to moisture, and electrical and thermal ratings. This standard outlines specific recommend
30、ations dealing with the installation of electrical resistance trace heating systems for the intended use. Copyright 2012 IEEE. All rights reserved. viii Contents 1.

Overview 1.1 Scope This standard provide
37、s 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 applicati
38、ons 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;
39、roof, gutter, and pavement deicing; and other applications as shown in Table 1 in 4.1. Commercial applications involving hazardous (classified) locations shall also meet the relevant hazardous location requirements in IEEE Std 515TM 1as well as any other applicable codes and standards. 1Information

41、ents to ensure that adequate material temperatures are maintained and that electrical, thermal, mechanical, and water-exclusion durability are provided to the trace heating system. In addition, the requirements provide that under normal use the products will exhibit long-term performance reliability
42、 to reduce the potential for damage to the user or surroundings. This standard is a supplement to those provisions outlined in National Electrical Code(NEC) (NFPA 70), Articles 426 and 427. 2.
