This test includes both the intensity of the UV-A radiation and the illumination strength. The observation conditions for this test procedure are described in DIN EN ISO 3059, which contains the minimum illumination level and the UV-A radiation strength and its measurement. A calibration interval according to the manufacturer's specifications is also required, but at least every 12 months and the documentation must be carried out by means of a calibration certificate. M Kit also contains a protective rubber cover with stand for the special impact protection and an aluminum case for the protected storage and safe transportation.This text is machine translated.
