(c) Color and Appearance. Federal Standard 595; 38907 for yellow or 37925 for white. Evaluate color and appearance using the following: CIE 1976 L*a*b*, illuminant D 65, and standard observer angle 1931 CIE 2 degrees. The geometry shall be 45/0 or 0/45, or d/8, excluding specular gloss.
Take measurements from samples applied to an opacity chart, e.g., Leneta Form 2A, at a wet film thickness of 15 mils ± 1 mil. The applied sample shall have been allowed to dry for at least 12 hours before measurements are taken. The evaluation shall be as follows:
(1) Production. The color of the dry paint shall match the L*a*b* values provided, under the specified conditions. For white paint the values are: L* = 94.80, a* = -2.35, b* = 3.20. For yellow paint the values are: L* = 80.70, a* = 19.40, b* = 88.65. The colors shall match when compared instrumentally.
(2) Control. The maximum permissible variation from the specified L*a*b* values shall be 2.0 Δ Ecmc. Take measurements from a sample applied over the black portion of an opacity chart.
Batches will be approved based on a laboratory visual evaluation for blemishes and irregularities in the test specimen (e.g., cracks, flaking, surface depressions, pooling, etc.) that would interfere with the measurement of color and appearance on the opacity chart. The final decision will be as determined.
(3) Reflectance. The reflectance, without beads and using CIE XYZ Yxy shall be a minimum Y of 80 percent for white batches; and a minimum of 50 percent for yellow batches; with a maximum of 60 percent. Take measurements from a sample applied over the black portion of an opacity chart.
