Insulating and sheathing materials of electric cables. Common test methods - Part 4: Methods specific to polyethylene and polypropylene compounds Section 1: Resistance to environmental stress cracking. Wrapping test after thermal ageing in air. Measurement of the melt flow index. Carbon black and/or mineral content measurement in PE

Specifies the test methods to be used for testing polymeric insulating and sheathing materials of electric cables for power distribution and telecommunications including cables used on ships. Gives the methods for measurements of the resistance to environmental stress cracking, for wrapping test after thermal ageing in air, for measurement of melt flow index and for measurement of carbon black and/or mineral filler content, which apply to PE and PP coumpounds, including cellular compounds and foam skin for insulation.
