    Abstract

    This standard provides guide to evaluation and testing of color, color difference, gloss, metamerism, and miscellaneous optical properties of optical powder coatings by both visual and instrumental means. Visual evaluation of optical properties shall include visual gloss test method, Munsell Color Order System, and ASTM test standards indicated in the specification. Instrumental evaluation of optical properties shall include specular gloss test, filter photometry, reflection haze, fluorescence, and ASTM test standards indicated in the specification.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
