29.035.99 - Other insulating materials
EN IEC 60370:2018
Reemplaza a: BS 7831:1995
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 IEC 60455-3-5 and IEC 60464-3-2 and similar materials.
