The work of preparing International Standards is normal
27、ly 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-governmental, in liaison with ISO, also take part in the
28、 work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requ
29、ires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 10545-16 was prepared by Technical Committee ISO/TC 189, Ceramic tiles.

34、s a method for utilizing colour measuring instruments for quantifying the small colour differences between plain coloured glazed ceramic tiles, which are designed to be of uniform and consistent colour. It permits the specification of a maximum acceptable value which depends only on the closeness of
35、 match and not on the nature of the colour difference. Colour variations produced for artistic purposes are not covered in this part of ISO 10545. NOTE This test should only be used when small colour differences between plain coloured glazed tiles are important in a specification. 2 Normative refere

At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO 10545 are

38、 J03: Calculation of colour differences. 3 Definitions For the purposes of this part of ISO 10545, the following definitions apply. 3.1 chroma attribute of colour which is defined as deviation from grey of the same lightness NOTE The more a colour deviates from grey, the higher the chroma. 3.2 light
39、ness parameter which relates the colour to a continuous grey scale between white and black EN ISO 1054516:2000 Licensed Copy: sheffieldun sheffieldun, na, Mon Nov 20 03:11:28 GMT+00:00 2006, Uncontrolled Copy, (c) BSI 2 3.3 CIE1) 1976 L* a* b* (CIELAB) values values calculated from measured spectral

42、Principle Colorimetric measurements are made on reference standard tiles and a test specimen of tiles of the same colour and the differences are calculated. The calculated CMC colour difference (Ecmc) of a test specimen is compared to a reference value, using a previously agreed upon commercial fact
43、or (cf) or the cf commonly used in the tile industry, to determine the acceptability of the colour match. NOTE Colorimetry describes a measure of colour difference, not appearance difference. Calculations are only valid when the reference and test specimens have essentially the same gloss and textur
44、e. 5 Test equipment The instrument used for colour measurement shall be either a reflectance spectrophotometer or a tristimulus colorimeter. The instrument geometry shall conform to one of the four sets of illuminating and viewing conditions specified by the CIE. The instrument geometries are identi
45、fied by the convention: illuminating geometry/viewing geometry. The four allowed instrument geometries with their abbreviations are 45/normal (45/0), normal/45 (0/45), diffuse/normal (d/0) and normal/diffuse (0/d). If a diffuse geometry (d/0 or 0/d) instrument is used, the specular component of refl
46、ectance shall be included in the measurement. The angle between the sample normal and the illuminating beam in 0/d geometry and the angle between the sample normal and the viewing beam in d/0 geometry shall not exceed 10 o. 6 Procedure 6.1 Test specimens 6.1.1 Reference specimen Take one or more til
47、es containing the same pigments or combination of pigments as the test specimen to avoid the complications of metamerism. A minimum of five representative tiles is normally considered suitable. However, if only a limited number of tiles is available, the most representative tile(s) shall be used. 1)
