適用范圍：This method is intended for 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 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 method 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 those found by other determinations, e.g. instrumental or visual assessments of dyeings.
