The global standards for heat tracing systems are developed by IEC Technical Committee 27.  The scope of work for this committee is reproduced below:

Standardization in the field of industrial equipment and installations intended for electroheating, electromagnetic processing of materials and electroheat based treatment technologies Note: The scope of interest covers industrial installations with the use of the following equipment: – equipment for direct and indirect resistance heating; – equipment for electric resistance trace heating; – equipment for induction heating; – equipment using the effect of EM forces on materials; – equipment for arc heating, including submerged arc heating; – equipment for electroslag remelting; – equipment for plasma heating; – equipment for microwave heating; – equipment for dielectric heating; – equipment for electron beam heating; – equipment for laser heating; – equipment for infrared radiation heating. The list presents typical examples of equipment and its applications and is not exhaustive.

Titles in this committee’s bibliography appears to be stable.   As with all IEC titles, they are relatively narrow in scope compared with the titles promulgated by most US standards developing organizations.  Our interest lies primarily in the application of this technology within and around education community buildings.

While heat tracing generally goes un-noticed it is an essential part of cold weather safety.  It is wise to keep pace with its evolution with innovation in materials and controls with the lead.

We maintain this committee’s work on the standing agenda of our seasonal Snow & Ice colloquia; along with US standards developed by UL, IEEE, NEMA, NFPA, ICC, ASHRAE and a few others.  We also collaborate with the IEEE Education & Healthcare Facilities Committee on this topic.  See our CALENDAR for the next online meeting; open to everyone.
