IEC 62631-3-12:2024 specifies a method of test for the determination of volume resistance and volume resistivity of electrical insulation materials by applying a DC voltage. It covers casting resins described in IEC 60455-3-1, IEC 60455-3-2, IEC 60455-3-3, IEC 60455-3-4, IEC 60455-3-8 and similar products. For other specific types of materials, other standards or the general method described in…

This document specifies methods to determine the mechanical integrity of filters under defined conditions that can be encountered in abnormal operating environments. It describes the test methods for filter elements, independent of any ageing procedures like pulsing, loading, temperature cycles, wet conditions or others. The test procedure is intended for filters operating in the range of 0,24 m3…
