Abstract
What is ISO 5631-1 – Determination of the colour of papers and boards about?
ISO 5631-1 is the first part of the multi-series standard that is applicable to paper and board. ISO 5631-1 specifies a method for measuring the colour of paper and board by the diffuse reflectance method with the elimination of specular gloss.
ISO 5631-1 is 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 (C/2°) provided by an authorized laboratory, as described in ISO 2470-1 .
