| Organization: | ASTM |
| Publication Date: | 27 December 1973 |
| Status: | inactive |
| Page Count: | 7 |
| ICS Code (Solar energy engineering): | 27.160 |
scope:
This specification defines the solar constant and the zero air mass solar spectral irradiance for use in thermal analysis, thermal balance testing, and other tests of spacecraft and spacecraft components and materials.
This specification is based upon data from experimental measurements made from high-altitude aircraft, balloons, spacecraft, and the earth's surface. The stated accuracies are based on the estimated accuracies of the measurements, calibrations, and radiometric scales.
