The GB/T 3682.1-2018 standard specifies standard methods for determining the melt mass flow rate (MFR) and melt volume flow rate (MVR) of thermal plasticity plastics. MFR and MVR are key indicators for measuring the fluidity of plastics in the molten state. These tests provide important data for the processing performance of plastics. The standard describes in detail the test equipment, operation steps and calculation methods to ensure the accuracy and conformity of the test results. This standard applies to material performance evaluation in plastics production and quality control.
