P844.1
IEEE/CSA Standard for Skin Effect Trace Heating of Pipelines, Vessels, Equipment, and Structures - General, Testing, Marking, and Documentation Requirements
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(R) (NEC(R)) 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.
P844.2
IEEE/CSA Standard for Skin Effect Trace Heating of Pipelines, Vessels, Equipment, and Structures--Application Guide for Design, Installation, Testing, Commissioning, and Maintenance
This standard provides for the application of skin effect trace heating systems for pipes, vessels, and structures. It provides requirements for design, installation, maintenance, and repair of these systems in general industry for ordinary locations, as well as in hazardous areas with potentially explosive atmospheres. This standard, when used with other recognized codes and standards, is intended to cover skin effect trace heating systems in their entirety, including system design, specifications, installation, operation, testing, commissioning, and maintenance. This standard also addresses the following associated systems that are important to the performance of skin effect trace heating systems: a) Thermal insulation systems; b) Electric power supply systems; c) Electric grounding systems; and d) Control and monitoring systems.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.

These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
844-2000
IEEE Recommended Practice for Electrical Impedance, Induction, and Skin Effect Heating of Pipelines and Vessels
Recommended practices are provided for the design, installation, testing, operation, and maintenance of impedance, induction, and skin-effect heating systems. Thermal insulation and control and monitoring are addressed. General considerations for heating systems are discussed, covering selection criteria, design guidelines and considerations, power systems, receiving and storage, installation, testing, operations, and maintenance. These aspects are then discussed for each of the above types of systems, along with special considerations particular to each. These recommended practices are intended to apply to the use of these heating systems in general industry.
