GB/T 13021-1991 specifies a standard method for the determination of carbon black content in polyethylene (PE) pipes and fittings by thermogravimetry. This method accurately calculates the carbon black content based on thermogravimetry by calcining and pyrolyzing the sample. This standard provides a unified and standardized testing process for polyethylene (PE) pipe and fittings manufacturers and related testing institutions, which helps to ensure product mass and ensure that the carbon black content in polyethylene (PE) pipes and fittings meets the requirements, so as to ensure the performance and Stability of the product in practical applications.
