ÖNORM EN 16791

This European Standard defines metrics that can be used to evaluate and compare lighting conditions with respect to their potential to achieve non-image forming, eye-mediated effects of light in human beings. This European Standard also provides information for application in lighting practice with relevance for both the public and private domain. However, the scientific knowledge is not yet mature enough to craft specifications for lighting conditions that can achieve specific non-image forming effects in humans. Moreover, this European Standard does not give information on lighting practices related to shift work. This European Standard does not address health safety issues such as resulting from flicker, photobiological safety or the effects of non-visible optical radiation (ultraviolet and infrared radiation).
