GB/T 2377-2013 "Vat Dyes - Determination of Shade and Strength" applies to the determination of the shade and strength of vat dyes, specifying a unified testing procedure and evaluation criteria. The test requires the use of laboratory dyeing equipment to dye fiber fabrics with the sample and the standard sample under the same conditions, controlling the dyeing temperature with a constant temperature water bath. Results can be assessed through visual comparison or quantified detection using a spectrophotometer, with the shade and strength of the standard sample serving as a reference to evaluate the performance of the test sample, ensuring consistency in dye quality.
