IEC 60704-1:2021 is available as IEC 60704-1:2021 RLV<\/span> which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 60704-1:2021 applies to electric appliances (including their accessories or components) for household and similar use, supplied from mains or from batteries. By “similar use” is understood the use in conditions similar to those found in households, for example in inns, coffee houses, tea rooms, hotels, barber or hairdresser shops, launderettes, etc., if not otherwise specified in the IEC 60704-2 series. This document does not apply to: \u2013 appliances, equipment, or machines designed exclusively for industrial or professional purposes; \u2013 appliances that are integrated parts of a building or its installations, such as equipment for air conditioning, heating and ventilating (except household fans, cooker hoods, free-standing heating appliances, dehumidifiers, air cleaners, and stand-alone water heaters), oil burners for central heating, pumps for water supply and for sewage systems;\u2013 separate motors or generators and \u2013 appliances exclusively for outdoor use. For determining and verifying noise emission values declared in product specifications, see IEC 60704-3:2019. This fourth edition cancels and replaces the third edition published in 2010. This edition constitutes a technical revision. It includes the following significant changes with respect to the previous edition: a) update of references (especially to ISO standards); b) revision of requirements on climatic conditions; c) revision of requirements on background noise level.<\/p>\n
