9、it- tee RA36; editorially revised and reaf- firmed 1989, 1999; reaffirmed 1994; revised 2002. 1. Scope 1.1 This evaluation procedure de- scribes the use of the standard depth scales for the determination of the dye concentration required to produce dye- ings of visually equal depth for the pur- pose
10、 of colorfastness evaluations. Color- ants may have different tinctorial strengths whereby equal concentration dyeings of them may differ markedly in the resulting color depth and colorfast- ness properties. Using concentrations of colorants which will give visually equal depths will provide a more
11、comparable evaluation. 2. Principle 2.1 Dyeings at a given concentration of dye are compared visually to the standard depth scales following the guidelines in AATCC Evaluation Procedure 9, Visual Assessment of Color Difference of Tex- tiles. If the perceived depths are not equal, the dye concentrati
12、on of the test specimen is adjusted until it is judged to be visually equal in depth to a specimen on the standard depth scales. 2.2 The standard depth scales consist of six sets of 12-18 fabric dyeings of dif- ferent hue and chroma and one set specif- ically for navy and black shades. All of the dy
13、eings in any set are considered to be of visually equal depth. 3. Terminology 3.1 colorant, n.a material which is applied to a substrate for the express pur- pose of changing the transmittance or re- flectance of visible light. NOTE: Dyes, pigments, tints and opti- cal brighteners are examples of co
14、lorants; soils are not colorants. 3.2 depth, n.departure of a colored object from white and frequently associ- ated with either concentration or effi- ciency of a colorant. 3.3 hue, n.the attribute of color per- ception by means of which an object is judged to be red, orange, yellow, green, blue, vi
15、olet or combination of these. 3.4 standard depth scale, n.in color measurement, a series of dyed samples of different hue and chroma that have been accepted to have the same depth. 3.5 tinctorial strength, n.the effec- tiveness of a given mass of dye in color- ing a given mass of material. 4. Descri
16、ption of the Scales 4.1 The primary range of 18 dyeings considered as the standard depth is desig- nated as “standard depths 1/1.” Double depths (designated as standard depth 2/1) and fractional depths (designated as stan- dard depths 1/3, 1/6, 1/12 and 1/25) pro- vide supplementary indices (see 8.1
17、). 4.2 The scales shall be equivalent to that established by the International Organiza- tion for Standardization (ISO) (see 8.2). 5. Use of the Scales 5.1 The dyeing of the standard scale that is closest in color to the test speci- men is selected. The test specimen is compared to the appropriate d
18、epth scale. Illuminate the surfaces with a daylight simulator with illumination level at the specimen plane in the range of 1080- 1340 lx (100-125 fc) (see 8.3). The test specimen is placed adjacent to the standard depth dyeing, and visually compared to it as described in AATCC Evaluation Procedure
19、9, estimating the approximate relative strength in relation to the scale. If the colors of the depth scale sample and that of the test specimen do not match, approximate the strength by visually interpolating between the two depth scales closest in color to the test specimen. If the test specimen is
20、 assessed to be unequal in depth to the scale, adjust the concentration of the colorant in the test specimen until the relative depth of the test specimen is considered to be equal to that of one of the six standard depths (see 8.4). 6. Report 6.1 Report the test specimen that was judged equal to th
21、e depth of a scale as be- ing equal to that scale; e.g., equal to 1/3 standard depth. 7. Precision and Bias 7.1 No statement is made regarding precision and bias of this evaluation pro- cedure since the result merely states whether there is conformity to the criteria for success specified in the pro
22、cedure. 8. Notes and References 8.1 Available from AATCC, P.O.

24、ired level; e.g., if a 1.0% dyeing produces a 1/1 standard depth, 2.0% does not necessarily produce a 2/1 standard depth. 8.5 Kuehni, Rolf G., “Standard Depth and Its Determination,” Textile Chemist and Colorist, Vol. 10, No. 4, pp22-25 (1978).
