Document Status Indicators The Green document status indicator indicates that the s903 is: Specifies a test method for the measurement of spectral absorptance, reflectance, and transmittance of materials using spectrophotometers equipped with integrating spheres. It is the responsibility of the user of this standard aetm establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Test Method E may be more appropriate to determine the bulk optical properties of textured or inhomogeneous materials.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the 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 ASTM E Standard test method for solar absorptance, reflectance, and transmittance of materials using integrating spheres.
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. This test method also provides a means for determining these values for extraterrestrial conditions. The Amber document status indicator indicates that some caution is needed when using this document – it e930 either: Again there may be more recent versions of awtm document.
Materials that are textured, inhomogeneous, patterned, or corrugated require special consideration. Historical Version s – view previous versions of standard. Direct and Diffuse on 20 Tilted and Vertical Surfaces. Free to use BIM project management tool provides step-by-step help to define, manage and validate responsibility for ee903 development and delivery at each stage of the asset life cycle in level 2 BIM projects.
Polarization effects may be detected by measuring the sample with rotation at various angles about the normal to the samples. The Red document status indicator indicates that the document is an old version The document has likely been withdrawn by the publisher, also the meta data presented here may be out of date qstm it is no longer being maintained by the editorial teams at NBS.

Link to Active This link will always route to the current Active version of the standard. Practice E describes outdoor methods using natural sunlight over the spectral r903 range of the human eye. Work Item s – proposed revisions of this standard. For polarizing samples, measurement data will be a function of the orientation of the sample.
