GB/T 730-2008 focuses on the quality control of blue wool master standard (1-7) in the colour fastness test of Spinning & weaving products. The standard specifies the mass indicators of the master standard, including key parameters such as Color characteristics, refractory Stability. Specify in detail the selection of raw materials in the production process, production process requirements, as well as storage and transportation conditions. At the same time, formulate inspection procedures and judgment criteria to ensure the stable and reliable quality of blue wool master standard. As an important reference for colour fastness assessment, strict quality control helps the Spinning & Weaving industry to obtain accurate and comparable colour fastness test results and ensure the mass of inspection work.
