NIST ANNOUNCES STANDARD REFERENCE MATERIAL (SRM) 2017 FOR THE PAINT INDUSTRY

摘要

NIST has developed SRM 2017 to aid the many industries dependent on gonioapparent (special visual effect) paints and coatings to improve the appearance of their products. Examples of gonioapparent paints include the pearlescent and metal-flake coating found on automobiles, which change color or brightness with viewing and/or illumination angle. The successful use of these special-effect paints, particularly in automobile manufacturing, requires measurement of the optical reflectance of the coatings as a function of angle to ensure that the paint application is performed correctly, is reproducible between manufacturing plants, is constant over time, and can be replicated during a repair.
