GB/T 41928-2022 stipulates the method of measuring the crosslinking degree of epoxy resin by differential scanning calorimetry (DSC). The standard specifies the scope of application, describes the principle of using DSC to detect the thermal characteristics of crosslinking epoxy resin to calculate the crosslinking degree, standardizes the equipment, sample preparation, test steps and result calculation process, and makes requirements for key parameters such as test temperature and scan rate. It provides a unified technical criterion for scientific and accurate determination of crosslinking epoxy resin crosslinking degree and helps evaluate the performance of epoxy resin products.
