ActiveTextiles - Tests for colour fastness - Grey scale for assessing staining
纺织品 色牢度试验 评定沾色用灰色样卡
Application Summary AI generated
This standard defines a grey scale used to visually assess the degree of staining on adjacent fabrics during color fastness testing. It is applied in textile quality control laboratories to evaluate how much dye transfers from a test specimen to other materials when exposed to conditions like washing, rubbing, or perspiration. The scale provides a standardized method for rating staining from 1 (severe) to 5 (no change), ensuring consistent evaluation across the textile industry.
