ASTM D5382-95

Standard Guide to Evaluation of Optical Properties of Powder Coatings

SCOPE
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 and health practices and determine the applicability of regulatory limitations prior to use.

Standard Guide to
Evaluation of Optical Properties of Powder Coatings
This standard is issued under the fixed designation D 5382; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
The term optical properties of coatings refers to those properties associated with the interaction of
visible light with the coatings. These properties include, but are not limited to, color, color difference,
gloss, and metamerism. Powder coatings users and producers may sometimes be overwhelmed by the
sheer number of standard practices and standard test methods available in ASTM for the evaluation
of the optical properties of coatings.
This guide is intended to lead the user to each of the practices and test methods needed, once the
user decides whether the evaluation is to be by visible means or by instrumental means. Further, the
user must decide which of the several optical properties mentioned above are to be evaluated. This
guide will lead the user to the applicable practices and test methods for the properties chosen by the
means selected.
