Abstract
A method for determining the time curve of the intensity of radiation present at the location of at least one sample which is being examined. The sample follows a circular path of movement in a sealed sample chamber of a weathering testing device, around a stationary radiation device for producing UW and global radiation. At least one sensor which detects the momentary radiation intensity of the radiation device is provided. The sensor moves together with the at least one sample, and is displaced in relation thereto in relation to the radiation device, for example in the peripheral direction of the path of movement. An electrical signal corresponding to the momentary intensity of the radiation is derived by the sensor at set intervals.
