GB/T 2384-2021 "General Method for Determination of Melting Range of Dye Intermediates" applies to the determination of the melting range of dye intermediates, specifying the capillary tube method as the core testing approach. It defines the specifications for capillary tubes and requirements for sample drying. The sample must be loaded into the capillary tube and compacted. A suitable heating device is used to control the heating rate, and the temperature range from the initial melting to the complete melting of the sample is recorded as the melting range. The standard includes requirements for instruments and equipment, operational procedures, result determination, and specifications related to precision to ensure the accuracy of the test results.
