This international safety standard applies to electronic apparatus designed to be fed from the MAINS or from a SUPPLY APPARATUS, from batteries or from REMOTE POWER FEEDING and intended for reception, generation, recording or reproduction of audio, video and associated signals. It also applies to apparatus designed to be used exclusively in combination with the afore-mentioned apparatus. This standard primarily concerns apparatus intended for household and similar general use but which may also be used in places of general assembly such as schools, theatres, places of worship and workplaces. PROFESSIONAL APPARATUS is also covered unless falling specifically within the scope of other standards. The committee responsible for this standard is Working Committee DKE/K 733 "Sicherheit für Geräte der Unterhaltungselektronik und verwandten Systeme" ("Safety of apparatus of consumer electronics and related systems") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
