          Revision Standard - Superseded.<br />\n
          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.<br />\n

          The scope of this project is to update the standard as it relates to present codes and industry practices. In addition, this project will develop guidelines with respect to the installation, testing, operation and maintenance of the conductors and terminations for all heating methods described in IEEE 844.<br />\n
          In accordance with IEEE requirements the 844 Recommended Practice is up for review. The publication in its present form does not address specific design, installation, testing, operation and maintenance guidelines with respect to conductors and terminations. Where applicable to IEEE 844, new industry practices will be reviewed and adopted.
