GB/T 33047.3-2021 is the third part of the thermogravimetric (TG) series of standards for plastic polymers. It stipulates that the activation energy of polymers is determined by the Ozawa-Friedman drawing method, and the reaction kinetics are analyzed, and the test principle, operation process and result calculation method are clarified. The standard is applicable to the thermogravimetric kinetic analysis of plastic polymers, providing a unified technical basis for material thermal stability research, research and development and production quality control, and ensuring the accuracy and conformity of relevant test data.
