The w
5、ork of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non- gover

Draft International Standards adopted by the technical committees are circulated to the member bodies for vo

International Standard ISO 105-Z10 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 1, Tests for coloured textiles and colorants. ISO 105 was previously publ

11、rength based on absorbance measurement of dye solutions. The relative colour strength is defined primarily by means of comparison of dyeings, which are prepared from the dye under test and the reference dye at the same depth. The relative colour strength is therefore the reciprocal ratio of the dye
12、concentrations, expressed as a percentage, hence it is a value defined by means of an application technique and is associated with the conditions of preparation of the dyeings and their evaluation. Despite this general limitation, determination of colour strength in solution is useful because of the
13、 decisive advantage of higher accuracy (reproducibility) with little expenditure of effort. The validity of the result should be controlled by comparison with evaluation by means of an application method.

16、r the determination of the colour strength of a dye in relation to that of a reference dye by means of spectrophotometric absorption measurements on solutions of dyes. NOTES 1 Basic requirements for this method are that the dye solutions do not scatter light and obey the Bougher-Lambert-Beer law as
17、well as identical or similar absorption curves of the samples and the reference in the visible region of the spectrum. 2 Identical or similar absorption curves are usually obtained if the tests are carried out for the purpose of dye production control of batches/deliveries of the same dye. This meth
18、od is not applicable for the evaluation of dyes with distinctly different adsorption curves. 3 The colour strength of a dye is not a physical constant, since it is dependent, for example, on the test medium and test method. The colour strength determined by this method therefore may differ from thos
19、e found by other determinations, e.g. instrumental or visual assessments of dyeings. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 105.

NOTE As the relative colour strength is determined
24、by a comparison with a reference dye, this is assumed to remain constant. It is essential therefore to ensure careful storage and control of the reference dye. Many dyes are hygroscopic and sensitive to oxidation. It is essential to protect the reference dye from exposure to light in firmly sealed c
