Introduction
Laboratory radiation sources generate radiation which is intended to simulate a defined “reference
sun” as perfect as possible, where the fitting to the spectral irradiance in the materials sensitive range
is most important. So far, the fitting is described verbally only (e.g. standards concerning artificial
weathering) and the user decides for himself if the spectral irradiance E(λ) indicated by the producer
of the laboratory radiation source agrees suitable enough with the “reference sun” for his specific
application or, occasionally, the classification describes the fitting to a wanted “reference sun” only
insufficiently (e.g. for standard

Introduction
Laboratory radiation sources generate radiation which is intended to simulate a defined “reference
sun” as perfect as possible, where the fitting to the spectral irradiance in the materials sensitive range
is most important. So far, the fitting is described verbally only (e.g. standards concerning artificial
weathering) and the user decides for himself if the spectral irradiance E(λ) indicated by the producer
of the laboratory radiation source agrees suitable enough with the “reference sun” for his specific
application or, occasionally, the classification describes the fitting to a wanted “reference sun” only
insufficiently (e.g. for standard weathering tests).
This document deals with a procedure for the determination of objective factors characterizing the
grade of fitting in quantity.
One procedure describes the grade of fitting of a laboratory radiation source to the defined reference
sun for specific spectral ranges. A second procedure results in characterizing parameters for the
respective wavelength ranges, incorporating known action spectra.
