GB/T 1632.3-2010 "Plastics - Determination of the viscosity of polymers in dilute solution using capillary viscometer - part3: Polyethylenes and polypropylenes"

GB/T 1632.3-2010 "Plastics - Determination of polymer dilute solution viscosity using a capillary tubing Viscosity meter - Part 3: polyethylene (PE) and polypropylene (PP) ", specifies the method for determining the viscosity of polyethylene (PE) and polypropylene (PP) dilute solutions with a capillary tubing Viscosity meter. The standard specifies the test principle, equipment, sample prepative, test procedure and result calculation, etc., to provide a uniform specification for accurate determination of the viscosity of dilute solutions of two types of plastics, helping to evaluate the molecular characteristics and processing performance of polyethylene (PE) and polypropylene (PP).
