DS/EN ISO 105-J05:2007 Textiles - Tests for colour fastness - Part J05: Method for the instrumental assessment of the colour inconstancy of a specimen with change in illuminant (CMCCONO2)
This part of 105 provides a colorimetric method for calculating an estimate of the magnitude (andoptionally the direction) of the change in the perceived colour of a textile specimen when the chromaticity of the illumination by which it is viewed is changed. It therefore provides an estimate of the colour inconstancy of the specimen.NOTE 1: Colour inconstancy and metamerism are related but distinct. With respect to a change in the quality of illumination,a) colour inconstancy is the extent of change in the colour appearance of a single specimen,b) metamerism is the extent of change in the colour difference between two specimens.This part of 105 therefore pr
