Description of BS 6923:1988 1988This British Standard provides a method of calculating the colour difference between two specimens of the same material, measured under the same conditions, such that the numerical value DE, the total colour difference, quantifies the perceptibility of the colour difference or the accept ability of the colour match. The latter permits the specification of a maximum value which depends only on the closeness of match required for a given end-use and not on the colour involved nor on the nature of the colour difference.
Describes a method using a modification of the internationally recognized CIELAB colour difference formula.
