AbolishedElectrical insulating materials―Thermal endurance properties―Part 8: Determination of thermal endurance indices (TI and RTE) of an insulating material using the fixed time frame method
电气绝缘材料 耐热性 第8部分：用固定时限法确定绝缘材料的耐热指数（TI和RTE）
Application Summary AI generated
This standard specifies the fixed time frame method for determining the thermal endurance indices (TI and RTE) of electrical insulating materials. It is applied in the electrical engineering industry to evaluate and compare the long-term thermal aging resistance of materials used in motors, transformers, and cables. The method enables manufacturers and testing laboratories to assign temperature ratings for insulation systems under accelerated thermal stress conditions.
