Scope
This document specifies a method for measuring the colour of paper and board by the diffuse reflectance method with the elimination of specular gloss.


This document is not applicable to coloured papers or boards which incorporate fluorescent dyes or pigments. It may be used to determine the colour of papers or boards which contain fluorescent whitening agents provided the UV content of the illumination on the test piece has been adjusted to conform to that in the CIE illuminant C, using a fluorescent reference standard that fulfils the requirements for international fluorescent reference standards of level 3 (IR3) as prescribed by ISO 2469 with an assigned ISO brightness value provided by an authorized laboratory, as described in ISO 2470-1.
