Gray Scale for Staining
|Publication Date:||1 January 2012|
This evaluation procedure describes the use of the Gray Scale for evaluating staining of textiles resulting from colorfastness tests. A precise colorimetric specification of the differences between the reference and the 9-step Scale is given as a permanent record against which newly prepared Gray Scales, and old Scales that may have changed, can be compared.
