ASTM D5382-02-2017 Standard Guide for Evaluating Optical Properties of Powder Coatings

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.


1.1 This standard provides users with guidance on the various practices and test methods available for the assessment of colour, chromatic aberration, lustre and isochromia by visual and instrumental means.

1.2 This standard is not intended to address all, if any, safety concerns associated with its use. It is the responsibility of users of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.

1.3 This international standard is based on the internationally recognized standardization principles established in the Decision on Principles for the Development of International Standards, Guidelines and Recommendations issued by the WTO Committee on Technical Barriers to Trade (TBT).
