INSULATION LIFE SUBCOMMITTEE

SCOPE

Study and review methods to determine maximum safe insulation temperatures, ambient temperatures, insulation aging characteristics, safe duration of loads in excess of nameplate (including short circuits) and also to determine methods of calculating or measuring temperatures reached during both transient and steady state loads;
Develop and maintain related standards, recommended practices and guides for such criteria;
Coordinate with other technical committees, groups, societies and associations as required.
