[中文适用范围]： 本标准适用于由电网供电或由二次电池（充电电池）或一次电池（干电池）供电的家用及类似用途的电动剃须刀、电动理发剪或电动修剪器。 "类似用途" 指在酒店、医院、商店、办公室等场所的使用。本文件不适用于非电动供电（例如弹簧驱动）的剃须刀、理发剪或修剪器。如果可能，本文件也可适用于类似的电动设备，例如脱毛器。本文件规定了用于确定电动剃须刀、电动理发剪或电动修剪器发出的空气噪声的测试代码，特别是关于声源尺寸和噪声类型的特定要求。 [外文原描述]： IEC 60704-2-8:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. 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.
