ActiveElectrical insulating materials—Thermal endurance properties—Part 7: Determination of relative temperature index(RTI) of an insulating material
电气绝缘材料 耐热性 第7部分：确定绝缘材料的相对温度指数（RTI）
Application Summary AI generated
This standard specifies the test method for determining the Relative Temperature Index (RTI) of electrical insulating materials, which indicates the material's thermal endurance over time. It is applied in the electrical and electronics industries to evaluate and compare the long-term heat resistance of insulating materials used in motors, transformers, cables, and other electrical equipment. Manufacturers and testing laboratories use this standard to qualify materials for safe operation at specified elevated temperatures.
