11、0.1 Precision. Precision for this test method has not been established. There is no contemplated activity to establish precision for this method. Users of the method should use standard statistical techniques in making any comparisons of test results for either within-laboratory or between-laborator
12、y 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 values. As a means of estimating these properties, the method has no known bias. 7 Copyright International Organization for Standardization

14、rm to CIE Iilluminant D, and the CIE 1964 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
15、. Therefore, the following equations are 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 comp
16、arisons (see NOTE 1 in 8.2). For FWA-treated specimens, the use of illuminant C may give misleading results with respect to visual assessments.
