Electrical insulating materials. Thermal endurance properties - Determination of thermal endurance indices (TI and RTE) of an insulating material using the fixed time frame method Ingestion-build-209208 legacy heat pumps) with a1 Scope This part of IEC 60216 specifies the experimental and calculation procedures for deriving the thermal endurance characteristics, temperature index (TI) and relative thermal endurance index (RTE) of a material using the fixed time frame method (FTFM). In this protocol, the ageing takes place for a small number of fixed times, using the appropriate number of ageing temperatures throughout each time, the properties of the specimens being measured
