scope:

This standard specifies the test methods to be used for testing polymeric insulating and sheathing materials of electric and optical cables for power distribution and telecommunications including cables used on ships and in offshore applications. This part 4-1 gives the methods for measurement of the resistance to environmental stress cracking, for measurement of melt flow index, for measurement of carbon black and/or mineral filler content by direct combustion, for measurement of carbon black content by thermogravimetric analysis (TGA) and for assessment of carbon black dispersion in polyethylene using a microscope which apply to PE and PP compounds, including cellular compounds and foam skin for insulation.
