[中文适用范围]： 本文件适用于家用和类似用途的电动剃须刀、理发器或修剪器，由电源或二次电池或一次电池供电。 术语“类似用途”理解为在酒店、医院、商店、办公室等的使用。 注101 本文件不适用于非电动方式（例如通过弹簧装置）驱动的剃须刀、理发器或修剪器。 注102 如果可能，本文件也可适用于类似的电动设备，如脱毛设备。 ISO 3743-1、ISO 3743-2和ISO 3744中规定的方法可用于测量剃须刀、理发器或修剪器发出的噪声。 ISO 3744:2010中规定的方法适用于任何尺寸的噪声源。对于噪声源尺寸的限制，参见ISO 3743-1:2010的第1.2条和ISO 3743-2:2018的第5条。 [外文原描述]： IEC 60704-2-8:2020 applies to electric shavers, clippers or trimmers for domestic and similar use, supplied from mains or secondary batteries or primary batteries. 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. This Part 2-8 supplements or modifies the corresponding clauses in IEC 60704-1:2010, so as to establish the test code for shavers, hair clippers or trimmers.
