scope:

This standard specifies a method for the quantitative determination of small colour differences (see DIN 5033-1) for object colours (see DIN 5033-1). The formula was developed using pairs of specimens with small colour differences ΔE* < 5. Colour difference determinations may, for instance, be the basis for agreements on limits for tolerable variations of coloured products during their industrial or commercial production. The method in this standard applies for coloured products (e.g. textiles, coatings, plastics, prints, glass) that are to be evaluated in pairs for colour conformity, and which have small perceptible colour differences
