Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

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 has to decide 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 Technical Report 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.
