    Abstract - (Show below) - (Hide below)

    Defines classifications of solar simulators for use in indoor measurements of terrestrial photovoltaic devices; solar simulators are classified as A, B or C for each of the three categories based on criteria of spectral distribution match, irradiance non-uniformity on the test plane and temporal instability. Provides the required methodologies for determining the rating achieved by a solar simulator in each of the categories. The main change with respect to the previous edition consists of a redefinition of the classifications and additional measurement procedures.
