Abstract
IEEE 622 Working Group has produced three recommended practices that are available through IEEE publications. The subject of these practices is electric heat tracing systems. IEEE Std 622-1987 (IEEE Recommended Practice for the Design and Installation of Electric Heat Tracing Systems for Nuclear Power Generating Stations) was originally issued in 1979 as a document specifically for use in nuclear power plants. This document was updated in 1987. The second document. IEEE 622A-1984 (IEEE Recommended Practice for the Design and installation of Electric Pipe Heating Control and Alarm Systems for Power Generation Stations), addresses the control and alarm systems for heat tracing systems, both nuclear and fossil. The third document IEEE 622B-1988 (IEEE Recommended Practice for Testing and Startup Procedures for Electric Heat Tracing Systems for Power Generating Stations) completes the series with the recommendations for commissioning the heat tracing systems. The working group proposes to combine the three documents into one. IEEE 622A and IEEE 622B continually refer to IEEE 622-1987 and the combination is not only justified but necessary in the interests of conciseness and ease of use. Other documents related to electric heat tracing are mentioned, and additional updates are discussed. Future tasks of the group are mentioned.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
