This standard specifies the method for determining the gelling degree of hard polyvinyl chloride (PVC) (PVC-U) products using a torque Rheometer, which is suitable for the evaluation of gelling degree of PVC-U products and their processing. Through this standard, the structural changes of PVC-U under thermal and mechanical action can be accurately analyzed, providing a scientific basis for production quality control.
