标准摘要
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.
