ASTM E Standard test method for solar absorptance, reflectance, and transmittance of materials using integrating spheres. Polarization effects may be detected by measuring the sample with rotation at various angles about the normal to the samples.

Measurements are typically made indoors using light sources other than natural sunlight, though it is possible to configure systems using natural sunlight as the illumination source, as in Practice E For polarizing samples, measurement data will be a function of the orientation of the sample. Work Item s – proposed revisions of this standard. This test method also provides a means for determining these values for extraterrestrial conditions.
