GB/T 43820-2024 "Spinning & weaving products, Spinning & weaving products containing phase change materials, Determination of thermal storage and exothermic performance" describes the use of differential scanning calorimetry (DSC) to determine the thermal storage and exothermic performance of Spinning & weaving products containing phase change materials. This standard applies to all types of Spinning & weaving products containing phase change materials, with the aim of evaluating their ability to absorb and release heat energy under changing temperature conditions. The standard refers to the relevant Spinning & weaving product moisture regulation test standards and mass determination methods to ensure the accuracy and comparability of the test process and results.
