1 Scope
This part of IEC 62631
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 IEC 62631‑3‑1 can be more suitable.
