Practice E describes outdoor methods using natural sunlight over the spectral response range of the human eye.

This test method provides a means for determining these values under fixed conditions that represent an average that would be encountered during use of a system in the temperate zone.

ASTM International offers global access to standards development for over participating countries. Measurements astk typically made indoors using light sources other than natural sunlight, asm it is possible to configure systems using natural sunlight as the illumination source, as in Practice E Polarization effects may be detected by measuring the sample with rotation at various angles about the normal to the samples.
