The IEEE/CSA Standard for Skin Effect Trace Heating of Pipelines, Vessels, Equipment, and Structures - General, Testing, Marking, and Documentation Requirements provides guidelines for the use of skin effect trace heating systems in various industrial applications. The standard covers both general requirements and specific testing, marking, and documentation requirements for these heating systems.

The scope of the standard applies to skin effect trace heating systems with a maximum rating of 5 kVac and a maximum skin effect insulated conductor temperature of 260°C. These systems are intended for installation in accordance with applicable national electrical installation codes, such as the CSA C22.1 in Canada or the NFPA 70 in the USA. The standard also addresses the use of skin effect trace heating systems in both ordinary and hazardous locations, such as Zone 1, Zone 2, or Class I, Division 2 areas.

In addition to the requirements for the heating systems themselves, the standard also covers termination assemblies and control methods used with skin effect trace heating systems. The purpose of the standard is to provide guidelines for testing, marking, design, and documentation to ensure that these heating systems can effectively maintain design temperature and provide durability and reliability in terms of electrical, thermal, and mechanical aspects.

It is worth noting that the standard does not cover certification requirements for voltages above 5 kVac or skin effect insulated conductor insulation temperatures above 260°C, as these may require special investigation by an accredited certification body. Information on transformer, power distribution, and control components can be found in a related standard, IEEE Std 844.2/CSA C293.2.2.
