Summary
This document specifies methods for the instrumental measurement of irradiance on a planar surface.
This includes not only natural solar radiation but also intensified natural solar radiation and radiation
produced by laboratory light sources.
For measurement of solar radiation for natural weathering and accelerated natural weathering,
instrumental techniques include the continuous measurement of total solar, solar ultraviolet and
spectral solar (ultraviolet) irradiance and the accumulation, or integration, of instantaneous data to
provide the radiant exposure.
For measurement of radiation in artificial accelerated weathering or artificial accelerated irradiation
exposures, instrumental techniques include the continuous measurement of total or defined wavelength
bands of ultraviolet radiation, visible spectral irradiance and/or ultraviolet spectral irradiance and the
accumulation, or integration, of instantaneous data to provide the radiant exposure.
This document does not specify procedures using blue-wool standards, chemical actinometry or
polymeric or other film dosimetry.
