标准摘要
[中文适用范围]： 本部分IEC 60216规定了通过"固定时间框架法(FTFM)"推导电气绝缘材料(EIM)的热耐久特性、温度指数(TI)和相对热耐久指数(RTI)的实验和计算程序。 在本协议中，老化在少量固定时间内进行，使用适当数量的老化温度，在每个时间结束时测量试样的性能。这与IEC 60216-1的程序不同，后者是在少量固定温度下进行老化，根据老化进度在老化时间后测量性能。 固定时间框架法中采用的诊断测试仅限于破坏性测试。该方法尚未应用于非破坏性或验证测试程序。 根据FTFM协议确定的TI和RTI均来自按照IEC 60216-1和IEC 60216-2的指令获得的实验数据，并按照本部分IEC 60216进行修改。计算程序和统计测试则修改自IEC 60216-3和IEC 60216-5。 [外文原描述]： IEC 60216-6:2022 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60216-6:2022 specifies the experimental and calculation procedures for deriving the thermal endurance characteristics, temperature index (TI) and relative temperature index (RTI) of an electrical insulating material (EIM) 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 at the end of the relevant time interval. This differs from the procedure of IEC 60216-1, where ageing is conducted at a small number of fixed temperatures, property measurement taking place after ageing times dependent on the progress of ageing. The diagnostic tests employed in the fixed time frame method are restricted to destructive tests. The method has not yet been applied to non-destructive or proof test procedures. This edition includes the following significant technical changes with respect to the previous edition: - clarification of definition of index properties vs. endurance properties; - complete rework of Annex G and the corresponding program.
