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. Practice E describes outdoor methods using natural sunlight over the spectral response range of the e93 eye. Materials that are textured, inhomogeneous, patterned, or corrugated require special consideration.

The Amber document status indicator indicates that some caution is needed when using this document – it is either: Specifies a test method for the measurement of spectral absorptance, reflectance, zstm transmittance of materials using spectrophotometers equipped with integrating spheres. Direct and Diffuse on 20 Tilted and Vertical Surfaces.


Measurements are typically made indoors using light sources other than natural sunlight, though it is asmt 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. ASTM E Standard test method for solar absorptance, reflectance, and transmittance of materials using integrating spheres.
