New Standard Will Aid in Color Calculation of Objects
ASTM Committee E12 on Color and Appearance
According to ASTM member Hugh Fairman, legacy standard E308 gathered data and pre-calculated weight sets for doing what is called “tristimulus integration,” which determines the actual color of a measured spectral reflectance or spectral power curve. While this standard is still useful in certain cases, a need has grown for the more updated practice described in E3415 to respond to interest in how illumination is perceived on painted surfaces.
