GB/T 28724-2012 "Determination of Melting Point for Solid Organic Chemicals—Differential Scanning Calorimetry" specifies the method for determining the melting point of solid organic chemicals using differential scanning calorimetry. This method involves programmed temperature control to measure the change in heat flow of the sample relative to a reference material during phase transition, thereby determining the onset temperature or peak temperature of melting as the melting point.
