Textiles -- Tests for colour fastness -- Part A03: Grey scale for assessing staining
This standard was last reviewed and confirmed in 2014. Therefore this version remains current.
Describes the grey scale for determining staining of adjacent fabrics in colour fastness tests, and its use. A precise colorimetric specification of the scale is given as a permanent record against which newly prepared working standards and standards that may have changed can be compared. The essential scale (5 steps) consists of pairs of non-glossy grey or white colour chips (or swatches of grey or white cloth). In addition, an augmented scale includes four half-steps and, thus, 9 steps.
