ActiveElectrical insulating materials—Thermal endurance properties—Part 8: Determination of thermal endurance indices (TI and RTI) 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RTI）
Application Summary AI generated
This standard specifies the fixed time frame method for determining the thermal endurance indices (TI and RTI) of electrical insulating materials. It is applied in the electrical and electronics industries to evaluate and compare the long-term thermal aging resistance of materials used in transformers, motors, cables, and other high-temperature equipment. The standard provides a standardized testing context for manufacturers and quality assurance labs to classify insulation materials based on their thermal performance under accelerated aging conditions.
