Electric and optical fibre cables. Test methods for non-metallic materials - Mechanical tests. Methods specific to polyethylene and polypropylene compounds. Wrapping test after thermal ageing in air Ingestion-build-47786 Helical-scan digital video cassette recording1 Scope This Part 510 of IEC 60811 specifies the test method for a wrapping test after thermal ageing in air. This test method applies specifically to polyolefin insulation in communication cables. This test is intended for polyolefin insulations of unfilled cables and of dry cores for filled cables, where the insulation has a wall thickness of less than or equal to 0,8 mm.
