GB/T 2951.41-2008 is a special test standard for polyethylene (PE) and polypropylene (PP) mixtures in cable and optical cable insulation and sheath materials. It covers a variety of key test methods such as environment stress cracking resistance and melt index measurement, which can evaluate the performance of materials under different conditions. Carbon black and mineral filler content in polyethylene (PE) can be measured by direct combustion and thermogravimetric analysis, and carbon black Carr Dispersibility can be evaluated by Microscope method. Provide comprehensive and standardized testing basis for cable and optical cable manufacturers to control material mass and ensure product performance.
