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.
1.1 This standard provides the user with a guide to the various available practices and test methods for the evaluation of color, color difference, gloss, and metamerism by both visual and by instrumental means.
1.2 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
