The radiation power emitted from the UV radiation sources () in a weathering apparatus is controlled such that the radiation power of each of the radiation sources () is measured in a predetermined spectral range of the radiation emitted from the radiation sources, with the spectral range being chosen such that the measured radiation power is representative of the radiation power in the UV, an averaged radiation power is calculated from the measured radiation powers, and the averaged radiation power is used for controlling the electrical power to be supplied to the radiation sources (). In particular, the control process can be carried out in such a way that the same electrical power, within a predetermined tolerance bandwidth, is supplied to each of the radiation sources (), and the averaged radiation power is kept constant over time at a desired nominal value.
