17、 105-J05:2007ii iiiForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a su

18、bject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (

19、IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical commi

20、ttees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not b

21、e held responsible for identifying any or all such patent rights. ISO 105-J05 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 1, Tests for coloured textiles and colorants. ISO 105 was previously published in 13 “parts” under the general title Textiles Tests for colour fastne

22、ss, each designated by a letter (e.g. “Part A”), with publication dates between 1978 and 1985. Each part contained a series of “sections”, each designated by the respective part letter and by a two-digit serial number (e.g. “Section A01”). A complete list of these parts is given in ISO 105-A01. EN I

23、SO 105-J05:2007blank1Textiles Tests for colour fastness Part J05: Method for the instrumental assessment of the colour inconstancy of a specimen with change in illuminant (CMCCON02) 1 Scope This part of ISO 105 provides a colorimetric method for calculating an estimate of the magnitude (and optional

24、ly 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 changed. It therefore provides an estimate of the colour inconstancy of the specimen. NOTE 1 Colour inconstancy and metamerism are related but distinct. Wi

25、th 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) 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)

26、 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) in 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

27、 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) of the specimen are measured or computed using CIE Standard Illuminant D65 as reference illuminant and an agreed test illuminant. All calculations

28、are based upon the CIE 1964 Standard Colorimetric Observer. A chromatic adaptation transform (CAT02 simplified appropriately for the current application) is then applied to the tristimulus values in the test illuminant to determine the tristimulus values of the corresponding colour of the specimen i

29、n illuminant D65 (Xc, Yc, Zc). Finally, using the colour-difference formula specified in ISO 105-J03, the colour difference between the tristimulus values 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

30、 colour difference is the required Colour-Inconstancy Index, CMCCON02. NOTE 1 For further information on CMCCON02 and CAT02, see Reference 1 in the Bibliography. NOTE 2 The corresponding colour is the colour that would have the same appearance in illuminant D65 as it has in the test illuminant. EN I

39、difference calculated in 4.5 is the required CMCCON02, which is a measure of the magnitude of the colour inconstancy of the specimen between 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

40、it is necessarily colour constant between any other pair of illuminants.) The larger the value of CMCCON02, the more colour-inconstant is the 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 T

41、est report The test report shall include the following: a) the number and year of publication of this part of ISO 105; b) all details necessary for complete identification of the specimen; c) identification of the colorimeter or spectrophotometer, including the CIE geometry type, with which the inpu

42、t 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 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) th

43、e value of CMCCON02, e.g. CMCCON02 = 3,1; i) if desired, the components L*, C*, andH* of CMCCON02.
