17、ons. 2 EN ISO 105-J05:2007 (E) 1 Scope This part of ISO 105 provides a colorimetric method for calculating an estimate of the magnitude (and optionally the direction) of the change in the perceived colour of a textile specimen when the chromaticity of the illumination by which it is viewed is change

18、d. 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)

19、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 Comparison of the results of this method and those from visual assessments is valid only when the visual assessments are made a) i

20、n lighting of the same spectral power distributions as used in the colorimetric calculations, b) with the specimens illuminated at 1 000 lux to 4 000 lux, c) by an assessor who is fully adapted to the relevant viewing conditions. 2 Principle The tristimulus values (Xr, Yr, Zrand X, Y, Z respectively

21、) of the specimen are measured or computed using CIE Standard Illuminant D65 as reference illuminant and an agreed test illuminant. All calculations are based upon the CIE 1964 Standard Colorimetric Observer. A chromatic adaptation transform (CAT02 simplified appropriately for the current applicatio

22、n) is then applied to the tristimulus values in the test illuminant to determine the tristimulus values of the corresponding colour of the specimen in illuminant D65 (Xc, Yc, Zc). Finally, using the colour-difference formula specified in ISO 105-J03, the colour difference between the tristimulus val

23、ues of the corresponding colour in illuminant D65 (Xc, Yc, Zc) and the measured or computed values in illuminant D65 (Xr, Yr, Zr) is calculated. This colour difference is the required Colour-Inconstancy Index, CMCCON02. NOTE 1 For further information on CMCCON02 and CAT02, see Reference 1 in the Bib

24、liography. NOTE 2 The corresponding colour is the colour that would have the same appearance in illuminant D65 as it has in the test illuminant. 3 EN ISO 105-J05:2007 (E) 3 Normative references The following referenced documents are indispensable for the application of this document.

32、and those measured or computed for the specimen in illuminant D65 (Xr, Yr, Zr) as standard according to ISO 105-J03. 5 Interpretation of results 5.1 The colour difference calculated in 4.5 is the required CMCCON02, which is a measure of the magnitude of the colour inconstancy of the specimen between

33、 the test illuminant and illuminant D65. If CMCCON02 is sensibly zero, the specimen is colour constant between these two illuminants. (This does not imply that it is necessarily colour constant between any other pair of illuminants.) The larger the value of CMCCON02, the more colour-inconstant is th

34、e specimen. 5.2 If desired, cylindrical component differences (L*, C* and H*) may be reported in order to indicate the nature and direction of the CMCCON02. 6 Test report The test report shall include the following: a) the number and year of publication of this part of ISO 105; b) all details necess

35、ary for complete identification of the specimen; c) identification of the colorimeter or spectrophotometer, including the CIE geometry type, with which the input data were obtained; d) the date of the test; e) identification of the test illuminant, e.g. illuminant A; f) the origin of the illuminant

36、D65 and test illuminant weighting functions, e.g. ASTM E308-01 3; g) the colour-difference formula used to calculate the value of CMCCON02, e.g. CMC(1:1); h) the value of CMCCON02, e.g. CMCCON02 = 3,1; i) if desired, the components L*, C*, andH* of CMCCON02. 5 EN ISO 105-J05:2007 (E) Annex A (inform
