ASTM E892 Standard Tables for Terrestrial Solar Spectral Irradiance at 37 Air Mass for a 1.5 Degree Inclined Surface

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM E892 testing. These tables describe an air mass 1.5 solar spectral radiation distribution for use in all solar applications where a standard terrestrial solar energy is used.

Spectral radiation is required for the diffuse and direct portion of solar radiation incident on a 37° inclined surface facing the sun.

The air mass zero (AM0) spectrum used to generate the terrestrial spectrum was provided by C. Frohlich and C. Wehrli and is the revised and expanded Neckel and Labs spectrum. Neckel and Labs revised their spectra, citing Hardrop's work, using newer limb dimming data to convert from luminosity to luminescence, as reported by Frohlich. Comparisons by Frohlich with calibrated solar photometer data from Hawaii's Mauna Loa show that this new extraterrestrial spectrum is the best currently available.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.
