This method is intended for determining 1/1 standard depth of a dyeing on any textile material by a color-imetric method as a permitted alternative to the visual method described in clause 12 of ISO 105-A01:1994.
This method is applicable to 1/1 standard depth of colour only. Its use for other standard depths is under consideration.
NOTE 1 Specimens which this colorimetric method indi-cate to be of 1/1 standard depth may differ from specimens which are visually assessed to be of 1/1 standard depth by comparison with physical standards known to be of 1/1 standard depth. These differences may lead to differences in the results of tests applied subsequently. It is rec-ommended that the method of assessment of 1/1 standard depth, i.e. ISO 105-A06 or visual, be included in the report of tests subsequently applied.
