This International Standard gives guidance for evaluating the photobiological safety of lamps and lamp
systems including luminaires. Specifically it specifies the exposure limits, reference measurement
technique and classification scheme for the evaluation and control of photobiological hazards from all
electrically powered incoherent broadband sources of optical radiation, including LEDs but excluding
lasers, in the wavelength range from 200 nm through 3000 nm.
