21、 standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 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. Internationa
22、l organizations, governmental and non- governmental, in liaison with ISO, also take pari in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committee
23、s 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. International Standard IS0 105-JO2 was prepared by Technical Committee ISOTTC 38, Textiles, Subcommittee SC 1, Tests for coloured textile
24、s and colorants. This second edition cancels and replaces the first edition (IS0 105-J02:1987), which has been technically revised. IS0 105 was previously published in thirteen “paris”, each designated by a letter (e.9. “Part A), with publication dates between 1978 and 1985. Each part contained a se
25、ries of “sections”, each designated by the respective part letter and by a two-digit serial number (e.g. “Section A01”). These sections are now being republished as separate documents, themselves designated “parts” but retaining their earlier alphanumeric designations. A complete list of these paris
26、 is given in IS0 105-AO1. Annex A forms an integral pari of this part of IS0 105.

Tint, if other than zero, is an indication of a reddish or greenish hue having shifted away from a bluish (neutral) hue with a dominant wavelength of 466 nm. The formulae for calcu
28、lation of whiteness and tint are those recommended by the CIEi). Whiteness as measured by this test method is an indication of how white the textile appears to an 1.3 only between specimens of the same type of textile. Because reflectance is affected by the nature of the surface of the textile, comp
29、arisons can be made 1.4 The application of the formulae is restricted to specimens that are called “white“ commercially, that do not differ much in colour and fluorescence and that are measured on the same instrument at nearly the same time. Within these restrictions, the formulae provide relative,
30、but not absolute, evaluations of whiteness that are adequate for commercial use when employing measuring instruments having suitable modern and commercially available capabilities. i) International Commission on Illumination, Vienna. 1 - STDmBSI BS EN IS0 105-J02-ENGL 2000 - LbZLibbq OBbL85L 339 W E
31、N IS0 106-502:1999 1.5 Many impurities in textiles absorb short wavelength light, resulting in a yellowish appearance to observers. Therefore, a measurement of whiteness may be an indication of the degree to which a textile is free from impurities. 1.6 The effect of blueing components or fluorescent
32、 whitening agents (FWAs) on the whiteness of textiles may also be determined using the whiteness measurement. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of IS0 105.

Precision for this test method has not been established. There is no contemplated activity to establish precision for this method. Users of the method
38、should use standard statistical techniques in making any comparisons of test results for either within-laboratory or between-laboratory averages. 10.2 Bias. The whiteness and tint of textiles can be defined only in terms of a test method. There is no independent method for determining the true value

As a means of estimating these properties, the method has no known bias. 7 STDmBSI BS EN IS0 205-JOZ-ENGL 2000 E Lh24bb9 0861857 857 EN IS0 106-502:1999 Annex A (normative) Method for Illuminant C/2“ observer Tristimulus colorimeters typically do not conform to CIE Iilluminant Dh5 and the CIE 196
40、4 10“ observer. Most produce calculations for CIE Illuminant C and the CIE 193 1 2“ observer. Although the CIE Publication 15.2 recognizes whiteness and tint calculations for the CIE 1931 2“ observer, it does not recognize calculations for the CIE Illuminant C. Therefore, the following equations are
41、 given for those users of tristimulus colorimeters that have no other choice but to perform calculations for Illuminant C and the 193 1 2“ observer. Bear in mind however, that these calculations are to be used only for relative “in-house“ measurements and comparisons (see NOTES 1 and 2 in 8.2). For
