GB/T 250-2008 《Textiles—Tests for colour fastness—Grey scale for assessing change in colour》 Related products
This standard specifies the specifications and methods for the use of grey sample cards used to assess discoloration in the colour fastness test of Spinning & weaving products. Color changes in Spinning & weaving products in the colour fastness test are recorded and compared through an accurate Formula Guide. This standard adopts the translation version of ISO 105-A02:1993 and makes editorial changes to add requirements for background and covering material Color when using grey sample cards. The standard was proposed by the China Spinning & weaving Industry Association and is under the jurisdiction of the National Spinning & weaving Standardization Technical Committee. Compared with the previous version, this standard adjusts the scope of application and updates the relevant requirements.
