IEC 60825-1 Edition 3 features a new subclause 4.4 which – provided that several requirements are fulfilled - permits classification of a laser illuminated light source as Class 1 under IEC 60825-1 and classification of the accessible light emission under the IEC 62471 series (Photobiological safety of lamps and lamp systems). The practical application of the requirements of this subclause is discussed, as well as the recent IEC Interpretation Sheet on subclause 4.4.
