Scope

This standard specifies a general method for the determination of the crystallization point by the double-tube method. This standard is applicable to the determination of the crystallization point of dye intermediate products with a crystallization temperature in the range of -10 to 150°C. This standard is applicable to the direct determination of the crystallization point of the sample, and is also applicable to the determination of the crystallization point of the dried sample. Whether the sample needs to be dried and the drying method are specified in the product standard.
