Photovoltaic devices

Part 4: Reference solar devices – Procedures for establishing calibration traceability

(IEC 60904-4:2019 + COR1:2020); German version EN IEC 60904-4:2019 + AC:2020
Class/Status: Standard, valid
Released: 2021-06
VDE Art. No.: 0100623

This part of IEC 60904 sets the requirements for calibration procedures intended to establish the traceability of photovoltaic (PV) reference devices to SI units as required by IEC 60904-2.
This standard applies to PV reference devices that are used to measure the irradiance of natural or simulated sunlight for the purpose of quantifying the performance of PV devices. The use of a PV reference device is required in the application of 60904-1 and 60904-3.
