This Part 512 of IEC 60811 describes the procedure for testing tensile strength and elongation at break after conditioning at elevated temperature. It is specific to polyethylene and polypropylene compounds. This test is intended for samples from filled cables, of polyolefin insulations with a wall thickness of more than 0,8 mm and for polyolefin sheaths in direct contact with filling compound.

This Part 607 of IEC 60811 specifies test methods for carbon black dispersion that are applicable specifically to PE and PP compounds, including cellular compounds and foam skin for insulation.

This Part 605 of IEC 60811 describes the test methods for measuring the content of carbon black added for UV stabilization of polyethylene and polyolefin compounds. These methods are not suitable for halogenated compounds. Method A is suitable only for polyethylene and polypropylene compounds. Method B is suitable for polyolefine compounds.

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.

This Part 511 of IEC 60811 describes the procedure for the measurement of the melt flow index for polyethylene compounds.
