Again there may be more recent versions of the document. Link to Active This astj will always route to the current Active version of the standard.

For polarizing samples, measurement data will be a function of the orientation of the sample. Test Method E may be more appropriate to determine the bulk optical properties of textured or inhomogeneous materials.

Product Information

The Amber document status indicator indicates that some caution is needed when using this document – it is either: Materials that are textured, inhomogeneous, patterned, or corrugated require special consideration. It is the responsibility of the user e930 this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.


Direct Normal and Hemispherical on 37 Tilted Surface. Polarization effects may astn detected by measuring the sample with rotation at various angles about the normal to the samples.


Specifies a test method for the measurement of spectral absorptance, reflectance, and transmittance of materials using spectrophotometers equipped with integrating spheres. ASTM E Standard test method for solar absorptance, reflectance, and transmittance of materials using integrating spheres.

Historical Version s – view previous versions of standard.

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 This test method also provides a f903 for determining these values for extraterrestrial conditions.

The Red document status indicator indicates that the document is an old e9033 The document has likely been withdrawn by the publisher, also the meta data presented here may be out of date as it is no longer being maintained by the editorial teams at NBS.

Work Item s – proposed revisions of this standard. Document Status Indicators The Green document status indicator indicates that the document is: Direct and Diffuse on 20 Tilted and Vertical Surfaces. This test method provides a means for determining these values e9003 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 human eye. Want access to British Standards?
