New IEEE Standard - Active. General requirements, testing, markings, and documentation for skin effect trace heating systems for pipelines, vessels, equipment, and structures intended for use in general industrial applications are provided in this standard. This standard provides requirements when utilizing skin effect trace heating systems in ordinary as well as hazardous areas that have potentially explosive atmospheres.
This standard applies to general, testing, marking, and documentation requirements for skin effect trace heating systems rated up to and including 5 kVac and 260 °C maximum skin effect insulated conductor temperature. These heating systems are intended for installation in accordance with the CSA C22.1, Canadian Electrical Code, Part I (CE Code); NFPA 70, National Electrical Code® (NEC®) in the USA; or with any other national electrical installation code, as applicable. This standard applies to skin effect trace heating systems intended to be installed in ordinary and hazardous locations. The hazardous locations include the following: -- In Canada: Zone 1; Zone 2; Zone 21; Zone 22; or Class I, Division 2; Class II, Division 2; Class III, Division 2 as described in CSA C22.1. -- In the USA: Class I, Zone 1; Class I, Zone 2; Zone 21 and Zone 22; or Class I, Division 2; Class II, Division 2; Class III, Division 2 as described in the NEC. This standard also applies to termination assemblies and control methods used with skin effect trace heating systems. NOTE 1--Requirements for certification at voltages above 5 kVac or skin effect insulated conductor insulation temperatures above 260 °C may be considered under a special investigation by an accredited certification body. NOTE 2--Information on transformer, power distribution, and controls components can be found in IEEE Std 844.2/CSA C293.2.2
This standard provides testing, marking, design, and documentation requirements for skin effect trace heating systems. Skin effect heating systems are intended to a) Maintain design temperature; and b) Provide electrical, thermal, and mechanical durability and reliability
