GB/T 11026.1-1989 Guide for the determination of thermal endurance properties of electrical insulating materials--Part 1:General guidelines for ageing procedures and evaluation of test results (English Version)
This standard applies to insulating materials whose properties (especially those properties on which the insulation functionality depends in service) will irreversibly deteriorate with increasing temperature.
