This standard specifies a method of testing the colourfastness of articles for common use to artificial saliva. The method is particularly suitable for those articles that are intended to be taken into the mouth, or for which it can be foreseen that they will, when used, be taken into the mouth or come into contact with the mucous membranes. With the test it is established whether colouring materials can migrate from the articles for common use to the mouth or to the mucous membranes.
This standard does not apply to articles for common use that are intended to come into contact with foodstuffs or to those articles or parts of articles whose function is the release of colouring materials.
NOTE Examples of the latter are wax crayons and leads of pencil crayons.
The test method is applicable to all articles for common use, independent of the colouring procedure applied (e.g. dyeing, staining, coating). Possible mechanical wear (e.g. exposure of a coloured layer after mechanical abrasion of a finishing coat) is not taken into account.
