The work of preparing International Standards is normally carried out through IsO technicalcommittees.Eachmemberbodyinterestedinasubjectforwhichatechnicalcommitteehasbeer non-governmental, in liaison with isO, also take part in the work. isO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. rights.

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 Iso 105 therefore provides a method for assessing (a) but not (b). NOTE 2 C
