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. It is the responsibility of the user of this standard to establish e930 safety and health practices and determine the applicability of regulatory limitations prior to use. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

This test method also axtm a means for determining these values for extraterrestrial conditions.

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

ASTM International offers global access to standards development for over participating countries. Test Method Ashm may be more appropriate to determine the bulk optical properties of textured or inhomogeneous materials. For polarizing samples, measurement data will be a function of the orientation of the sample.

The Amber document status indicator indicates that some caution is needed when using this document – it is either: Historical Version s – view previous versions of standard. Direct and Diffuse on 20 Tilted and Vertical Surfaces. ASTM E Standard test method for solar absorptance, reflectance, and qstm of materials using integrating spheres. Document Status Aetm The Green document status indicator indicates that the document is: Materials that are textured, inhomogeneous, patterned, or corrugated require special consideration.

ASTM E Solar Reflectance – SYNLawn – CADdetails

Practice E describes outdoor methods using natural sunlight over the spectral response range of the human eye. Polarization effects may be detected by measuring the sample with rotation at various angles about the normal to the samples.

  CHRISTIAN GOLLIER THE ECONOMICS OF RISK AND TIME PDF

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

Measurements are typically made indoors using light sources other than natural sunlight, though it is possible to configure systems using natural sunlight as asstm illumination source, as in Practice E Work Item s – proposed revisions of this standard.
