SR EN 60811-4-1:2005

Insulating and sheathing materials of electric and optical cables. Common test methods. Part 4-1: Methods specific to polyethylene and polypropylene compounds. Resistance to environmental stress cracking. Measurement of the melt flow index. Carbon black and/or mineral filler content measurement in polyethylene by direct combustion. Measurement of carbon black content by termogravimetric analysis (TGA). Assessment of carbon black dispersion in polyethylene using a microscope

Specifies the test methods to be used for testing polymeric insulating and sheathing materials of electric and optical fibre cables for power distribution and telecommunications, including cables used on ships and in offshore applications. These test methods apply specifically to PE and PP compounds, including cellular compounds and foam skin for insulation. The principal changes with respect to the previous edition are listed below: a) the wrapping test after thermal ageing in air is deleted from this part of EN 60811. It is now given only in EN 60811-4-2; b) a thermogravimetric method is added for determination of carbon black content; c) a method is introduced for assessment of carbon black dispersion.
