What is BS EN IEC 60904 ‑ 9 about?

BS EN IEC 60904 ‑ 9 is a part of multi-series standard IEC 60904 that provides the definitions of and means for determining simulator classifications at the required irradiance levels used for electrical stabilization and characterization of PV devices. BS EN IEC 60904 ‑ 9 is applicable for solar simulators used in PV test and calibration laboratories and in manufacturing lines of solar cells and PV modules. The A+ category is primarily intended for calibration laboratories and has been introduced because it allows for a reduction in the uncertainty of secondary reference device calibration. This i...
