Introduction to the New Standards — IEEE STD 844.3™-2019 /CSA C22.2 No. 293.3-19 and IEEE STD 844.4™-2019/CSA C293.4-19 for Impedance Heating of Pipelines and Equipment

Through a joint standards development process between the Institute of Electrical and Electronic Engineers (IEEE) and the Canadian Standards Association (CSA), two new standards are now completed. These new standards are a certification standard, IEEE Std 844.3™-2019/CSA C22.2 No. 293.3-19 (Standard for Impedance Heating of Pipelines and Equipment — General, Testing, Marking and Documentation Requirements), and an application guide standard, IEEE Std 844.4™-2019/CSA C22.2 No. C293.4-19 (Standard for Impedance Heating of Pipelines and Equipment — Application Guide for Design, Installation, Testing, Commissioning and Maintenance). These standards detail requirements that have been added or clarified in the impedance heating system certification process. This paper also summarizes applications as well as new recommended installation practices included in the application guide.
