AATCC 107:2013 pdf download.Colorfastness to Water
8.5 Remove the tester from the oven and for each test specimen assembly, sep- arate the multifiber fabric and, if used, the adjacent fabric from the test fabric. Place the multifiber fabric and test fabric specimens separately on a wire screen in a conditioned atmosphere 21 ± 1°C (70 ± 2°F) and 65 ± 2% relative humidity over- night.
9. Evaluation Method for Color Change
9.1 Evaluate the test specimen for change in color by comparison with the Gray Scale for Color Change (AATCC Evaluation Procedure 1), or by using AATCC Evaluation Procedure 7, Instru- mental Assessment of the Change in Color of a Test Specimen, and record the numerical rating that corresponds to the appropriate one on the Gray Scale.
10. Evaluation Method for Staining (see 12.7)
10.1 Evaluate the staining of the multi- fiber fabric used (see 12.5) by compari- son with the Gray Scale for Staining (AATCC Evaluation Procedure 2), the AATCC 9-Step Chromatic Transference Scale (AATCC Evaluation Procedure 8), or Instrumental Assessment of Degree of Staining (AATCC Evaluation Procedure 12), and record the numerical rating that corresponds to the appropriate one on ei- ther of them. Report which scale is used (see 12.6).
11. Precision and Bias
11.1 Precision. Precision for this test method has not been established. Until a precision statement is generated for this test method, use standard statistical tech- niques in making any comparisons of test results for either within-laboratory or between-laboratory averages. 11.2 Bias. Colorfastness to water can be defined only in terms of a test method. There is no independent method for de- termining the true value. As a means of estimating this property, the method has no known bias.
