IEC 60904-2:2015 is available as IEC Standards+ 60904-2:2015 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 60904-2:2015 gives requirements for the classification, selection, packaging, marking, calibration and care of photovoltaic reference devices. This standard covers photovoltaic reference devices used  to determine the electrical  performance of  photovoltaic cells, modules  and arrays  under natural and simulated sunlight. The main  technical  changes with  regard to the  previous edition are as  follows:
- addition of a test procedure in simulated sunlight of subsequent measurement of primary and secondary reference device;
- definition of standard test conditions;
- reduction of allowed diffuse component for secondary reference cell calibration.
