Abstract
This standard provides guidance for the evaluation and testing of color, chromatic aberration, gloss, isochromatic spectrum and other optical properties of optical powder coatings by visual and instrumental means. The visual evaluation of optical performance shall include the visual glossiness test method, the Munsell color sequence system, and the ASTM test standards indicated in the specification. Instrumental evaluation of optical properties shall include specular glossiness testing, filter photometry, reflective fog, fluorescence, and ASTM test standards indicated in the specification.
