The term “similar use” is understood to mean the use in hotels, hospitals, shops, offices, etc. This document does not apply to shavers, clippers or trimmers that are powered by means other than electrical, for example by a spring-device. If possible, this document can also be applied to analogous electrically operated devices, such as depilating devices. This second edition cancels and replaces the first edition published in 1997. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the scope of the products has been enlarged to include hair clippers and trimmers; b) it includes standard deviations of sound power levels in 1.1.3; c) the normative references have been updated (ISO 3744:2010 and ISO 3743-1:2010); d) it is adjusted with respect to IEC 60704-1:2010; e) it has been updated to comply with the ISO/IEC Directives, Part 2. This Part 2-8 is intended to be used in conjunction with third edition (2010) of IEC 60704-1, Household and similar electrical appliances – Test code for the determination of airborne acoustical noise – Part 1: General requirements.
