Electric and optical fibre cables. Test methods for non-metallic materials - Electrical tests. Measurement of the permittivity at 23°C of filling compounds Ingestion-build-67170 Bending stiffness is regarded as1 Scope This Part 301 of IEC 60811 gives the procedure to determine the permittivity at 23 C which typically applies to filling compounds used for optical cables, communication cables and optical fibre cables.
