GB/T 2378-2012 "Acid Dyes - Determination of Dyeing Shade and Strength" specifies the methods for determining the dyeing shade and strength of acid dyes. It applies to the quality evaluation of acid dyes used for fibers such as wool and nylon. During testing, the sample and the standard sample are dyed under the same conditions, and the results are evaluated through visual inspection or instrumental measurement. The required equipment includes an electronic balance, a constant temperature water bath, dyeing apparatus, and a colorimeter. By adhering to uniform dyeing conditions and evaluation standards, this standard provides a unified basis for quality control of acid dyes.
