GB/T 2384-2021 《Dyes intermediates—General method for the determination of melting range》 Related products

This standard specifies a general method for determining the melting point of dyestuff intermediates using the capillary tubing liquid bath method and the capillary tubing Melting point meter method, which is suitable for the melting point determination of crystalline or powdered dyestuff intermediates. The standard refers to GB/T 8170-2008 numerical revision rules and limit value representation and determination, JJG130-2011 working glass liquid thermometer and JJG 701-2008 melting point tester to ensure the accuracy and conformity of test results.
