Standard Test Method for Multiangle Color Measurement of Metal Flake Pigmented Materials

Abstract

5.1 Instrumental Measurement Angles—This test method is designed to provide color data at specific measurement angles that can be utilized for quality control, color matching, and formulating in the characterization of metal flake pigmented materials. 5.2 Materials—This test method provides meaningful color information for metal flake pigmented materials. This test method has been tested and verified on paint and coatings, and the same principles should apply to plastics containing metallic flake. For materials containing pearlescent materials refer to Test Method E2539. 5.3 Utilization—This test method is appropriate for measurement and characterization of metal flake pigmented materials. These data may be used for quality control, incoming inspection, or color correction purposes. 5.4 Specimen Requirements—Even though a pair of specimens have the same color values at three angles, if there are differences in gloss, orange peel, texture, or flake orientation, they may not be a visual match. Note 2: Information presented in this test method is based upon data taken on metallic materials coatings. Applicability of this test method to other materials should be confirmed by the user.
