Color and appearance metrology facility
The NIST Physical Measurement Laboratory has established the color and appearance metrology facility to support calibration services for 0°/45° colored samples, 20°, 60°, and 85° specular gloss samples, research in the colorimetric characterization of gonioapparent including a new standards for metallic coatings and calibrated photographic and x-ray step tablets.
