Organization: ASTM International
Publication Date: 10 December 1997
Status: inactive
Page Count: 3
ICS Code (Colours and measurement of light): 17.180.20
scope:

1.1 This test method covers the measurement of solar reflectance of various horizontal and low-sloped surfaces and materials in the field, using a pyranometer. The test method is intended for use when the sun angle to the normal from a surface is less than 45 degrees.
