Scope

GB/T 11026.10-2019 is the English-translated version of 电气绝缘材料耐热性第10部分：利用分析试验方法加速确定相对耐热指数(RTEA) 基于活化能计算的导则.

GB/T 11026.10-2019 is the Chinese standard "Electrical insulation materials -- Thermal endurance properties -- Part 10: Accelerated determination of relative thermal endurance using analytical test methods (RTEA) -- Instructions for calculations based on activation energy".

Its scope clause reads: This part of GB/T 11026 specifies the evaluation procedure for the heat resistance of electrical insulating materials.

The program is based on the heat obtained by the thermal analysis method Evaluating the relative heat resistance of electrical insulating materials by the activation energy of the degradation reaction and a life point in the heat resistance map obtained by conventional heat aging tests Index (RTE).

This section only applies to aging reactions in which a specific reaction dominates and is directly related to the endpoint criteria. Its clauses include terms and definitions, abbreviations.
