Common test methods for insulating and sheathing materials of electrical cables - Part 4: Methods specific to polyethylene and polypropylene compounds. Section Two: Elongation at break after pre-conditionning - Wrapping test after pre-conditionning - Wrapping test after thermal ageing in air — 34 стр.
Gives the methods for measurement of elongation at break after pre-conditioning, for wrapping test after pre-conditioning, for wraping test after thermal ageing in air, for measurement of mass increase, for long-term stability test and for measurement of copper-catalysed oxidative degradation, which apply to polyolefin insulations.
