IEC 60216-6:20 22 RLV包含官方IEC国际标准及其红线版本。Redline版本仅提供英文版本，为您提供了一种快速简单的方法来比较IEC官方标准与其以前版本之间的所有变化。 IEC 60216-6:20 22规定了使用“固定时间框架法（FTFM）”推导电绝缘材料（EIM）的热耐久性特性、温度指数（TI）和相对温度指数（RTI）的实验和计算程序。在该方案中，老化发生少量固定时间，每次使用适当数量的老化温度，在相关时间间隔结束时测量样品的性能。这与IEC 60216的程序不同-如图1所示，当老化在少量固定温度下进行时，性能测量在老化时间之后进行，这取决于老化的进程。固定时间框架方法中采用的诊断试验仅限于破坏性试验。该方法尚未应用于无损或验证测试程序。与上一版相比，此版本包括以下重大技术变更: -澄清指数特性与耐久性特性的定义； -完成附件G和相应程序的返工。

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 appro-priate 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.
