DIN ISO 18314-3:2017-04

This part of DIN ISO 18314 specifies different methods of calculating special indices, which are generally used to describe lightness respectively jetness of samples including chroma or hue within one colour-coordinate. This part of ISO 18314 is applicable to tristimulus values and chromaticity coordinates calculated using colour-matching functions of the CIE 1964 standard colourimetric system. It can be used for the specification of colour stimuli perceived as belonging to a reflecting or transmitting object, where a onedimensional value is required. The responsible German committee for this standard is NA 078-00-03 AA "Allgemeine Prüfverfahren für Farbmittel und Füllstoffe" ("General test methods for colorants and extenders") at DIN Standards Committee Pigments and Extenders (NPF).
