GB/T 29597-2013 "Reactive Dyes — Determination of Alkali Stability" is applicable to the determination of alkali stability and salt-alkali stability of reactive dyes, specifying the specific testing principles and procedures. The test requires the use of equipment such as a magnetic stirrer (speed 500-600 r/min), a balance with a sensitivity of 0.01 g, and medium-speed qualitative filter paper. The stability is evaluated by observing the precipitation time of the dye in alkali solution or salt-alkali solution. If no dye precipitation occurs within 120 minutes, the alkali stability is considered to meet the standard. This standard provides a reliable basis for quality assessment of reactive dyes in alkaline environments.
