家用和类似用途电器 空气声学噪声测定用测试方法 第2-1部分：干式吸尘器的特殊要求

[中文适用范围]： IEC 60704-2-1:2026 规定了适用于家庭使用或类似家庭环境的市电供电及电池供电干式吸尘器（含其配件和充电站） airborne acoustic 噪声的测定方法。对于干湿两用吸尘器，干式清洁功能适用；湿式清洁功能则依据 IEC 60704-2-20 进行测试。地面清洁机器人的特殊要求参见 IEC 60704-2-17。本文件描述了按照 IEC 62885-2 标准，在正常工况下于地毯和硬质地面测定干式吸尘器噪声排放的方法。本第五版作废并取代 2020 年发布的第四版，属于技术性修订。与前一版本相比，本版本主要技术变更包括：a）与 IEC 60704-1:2021 保持一致；b）涵盖与消费者相关的测试方面；c）增强标准的稳健性并消除潜在漏洞；d）扩大适用范围，增加对充电站的噪声测量。本文件应配合 IEC 60704-1:2021《家用和类似用途电器— airborne 声学噪声测定试验方法—第 1 部分：通用要求》共同使用。 [外文原描述]： IEC 60704-2-1:2026 specifies the determination of airborne acoustical noise of mains operated and cordless dry vacuum cleaners including their accessories and docking stations for household use or under conditions similar to those in households. For wet and dry vacuum cleaners, the dry cleaning function applies. The wet cleaning function is measured in accordance with IEC 60704-2-20. Particular requirements for floor cleaning robots are specified in IEC 60704-2-17 . This document describes the determination of the noise emission of dry vacuum cleaners under normal operating conditions on carpet and hard floor in accordance with IEC 62885-2. This fifth edition cancels and replaces the fourth edition published in 2020. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) alignment with IEC 60704 1:2021; b) addressing consumer relevant testing aspects; c) robustness of standards and closing potential loopholes d) enlarged scope to include noise measurement on docking stations. This document is intended to be used in conjunction with IEC 60704-1:2021, Household and similar electrical appliances - Test code for the determination of airborne acoustical noise - Part 1: General requirements.
