Standard Practice for Establishing Color and Gloss Tolerances

SIGNIFICANCE AND USE
5.1 Color specifications are centered around exact positions in color space. Correspondingly, gloss specifications are centered around an exact position on the gloss scale. Because it is difficult to achieve these exact positions repeatedly, it is necessary to specify tolerances that are acceptable to both the buyer and the seller. This practice details the procedure for accomplishing this goal.
SCOPE
1.1 This practice describes a procedure for establishing tolerances and evaluating the color and gloss of specimens with respect to specified standards. This practice is appropriate for nonfluorescent opaque specimens.  
1.2 This practice does not indicate the extent of tolerances, but gives guidance on how they can be set. For product specification, the tolerances between specimens and the specified standard should be agreed upon between the purchaser and the seller.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

INTRODUCTION
Permissible color and gloss deviations from a standard are generally dependent upon the color
discrimination of the observer, on the lighting and surround in which the material is viewed, and on
special considerations related to the design, manufacture, and practical usage of the colored material
or object. The tolerances, therefore, may be influenced by economic, technical, psychological, and
practical requirements. In many circumstances, acceptability of color and gloss deviations from a
standard may differ appreciably from perceptibility for many reasons. With proper allowances,
perceptibility data can be used as an aid to develop permissible tolerances. Finally, these consider-
ations should result in a specification acceptable to both buyer and seller.

Permissible color and gloss deviations from a standard are generally dependent upon the color
discrimination of the observer, on the lighting and surround in which the material is viewed, and on
special considerations related to the design, manufacture, and practical usage of the colored material
or object. The tolerances, therefore, may be influenced by economic, technical, psychological, and

standard may differ appreciably from the perceptibility of deviations such as on-tone fading
preferences, large tolerances for luminance variation, nongreen bias, or nonyellow bias. perceptibility
for many reasons. With proper allowances, perceptibility data can be used as an aid to develop
permissible tolerances. Finally, the sum of all these considerations should result in a specification
acceptable to both buyer and seller.
