ASTM E991-98 - 10.6.1998
 
1. Scope

1.1 This practice describes procedures for measuring the colors of fluorescent specimens as they would be perceived when illuminated by daylight, and for calculating tristimulus values and chromaticity coordinates for these conditions.

1.2 This practice applies to the use of the one-monochromator spectrophotometer employing polychromatic illumination of the specimen and monochromatic detection of the radiant energy.

1.3 This practice can be used to provide specifications for fluorescent colors in either the 1931 or the 1964 CIE system.

1.4 This practice covers only fluorescent specimens that emit visible light. It is not intended for use with other types of luminescent materials such as phosphorescent, chemiluminescent, or electroluminescent.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
