    Defines methods of test for the determination of thermal endurance (temperature index) of electrical insulating resins and varnishes for impregnation purposes.

    Scope - (Show below) - (Hide below)

    This International Standard covers methods of test for the determination of thermal endurance (temperature index) of electrical insulating resins and varnishes for impregnation purposes. It is done by means of impregnating glass cloth and measuring electric strength or breakdown voltage before and after heat ageing. It covers the materials described in IEC60455‑3‑5 and IEC60464‑3‑2 and similar materials.
