What is "International Grey Scales" - Definition & Explanation

Two series of pairs of chips that show increasing contrast within pairs, and are used visually for comparing the differences in colour of textile specimens or the degrees of staining of transfer cloths attached to the test specimens, that occur during colour fastness testing.

a) Basic Scale for Assessing Change in Colour

A scale that consists of five pairs of non-glossy grey-coloured chips, and in which a fastness rating of 5 (indicating no colour change) at one end of the scale is represented by two identical grey chips, and a fastness rating of 1 (indicating a severe colour change) at the other end of the scale is represented by a pair of grey chips having a colour difference of 13,6 Cielab units.

b) Basic Scale for Assessing Staining

A scale that consists of one pair of white and four pairs of non-glossy grey- and white-coloured chips, and in which a fastness rating of 5 (indicating severe staining) at one end of the scale is represented by the pair of white chips, and a fastness rating of 1 (indicating severe staining) at the other end of the scale is represented by a pair of chips having a colour difference of 34,1 Cielab units.

NOTE:

Both scales may be augmented to form a 9-step scale by the provision of similar chips that illustrate the perceived colour differences corresponding to the half-step fastness ratings.
