Standard Practice for Calculating the Colors of Objects by Using the ASTM Method

Importancia y uso:

5.1 The practices contained in this standard are useful for all illuminants and observers whether they are standard CIE definitions or are custom to a single usage only. The methods were, however, developed to accommodate those users who have need for custom defined source and observer functions. These do not lend themselves to easy calculation of weight sets for tristimulus integration, and as such the methods contained herein were developed specially to accommodate those persons having this requirement. Because either method derives tristimulus values that are insignificantly different from each other, the only selection criterion between them is whether there is a need for custom functions or not.
