Standard Practice for Evaluation of Instrumental Color Difference with a Gray Scale

Importancia y uso:

5.1 The gray scale grade GS_C is useful to evaluate the color difference of any pair of colors that have been subjected to a test whose severity of result is nominated by color difference of the treated member to the untreated member. This includes, but is not limited to, scrub tests, exterior exposures, crocking tests, blocking tests, certain abrasion tests, and color transfer tests.

5.2 A major advantage of the instrumental method of obtaining gray scale grades is that under the visual method substantial screening and training of the operators in visual color assessment is required. No such burden is placed on the operators in this instrumental method.

5.3 The method is usually not used for staining tests which have their own gray scale for staining.
