This document is an adaptation to the structure and state of DIN EN 60601-1:2007 with the accompanying supplementary standards. For laser devices, this is a new "state of the art" which is necessary for compliance with the basic requirements of the medical products law. The German version is an identical technical takeover of the IEC version, so that there are no trade restrictions for the worldwide distribution of laser devices. In addition to the medical sector, the standard is also applicable to the cosmetics sector in order to achieve a uniform level of safety. The responsible committee is DKE/K 812 "Elektromedizinische Geräte" ("Electro-medical equipment") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
