家用和类似用途电器用于测定空气声学噪声的试验规范第2-3部分:洗碗机的特殊要求

[中文适用范围]： 一般补充：这些特殊要求适用于家用和类似用途的单机电动洗碗机@带或不带自动程序控制@用于冷和/或温水供应@用于可拆卸或永久连接到供水或污水系统@用于放置靠墙的地板@用于内置或放置在柜台下方@厨房操作台或水槽下方@用于壁挂式安装或柜台上。噪声类型替代： ISO 3743-1、ISO 3743-2 和 ISO 3744 中规定的方法可用于测量电动洗碗机发出的噪声。源的大小 更换：ISO 3744 中规定的方法适用于任何大小的噪声源。应用 ISO 3743-1 和 ISO 3743-2@ 时，应注意被测器具的最大尺寸满足 ISO 3743-1:2010 的 1.2 和 ISO 3743-2:1994 的 1.3 中规定的要求。对象添加：噪声发射值声明的要求不在本文件的范围内。注 101：要确定和验证产品规范中声明的噪声发射值，请参阅 IEC 60704-3。测量不确定度 替换：根据本文件确定的声功率级标准偏差的估计值在表 101 中给出：声明和验证的标准偏差 目的是根据 IEC 60704-3@ 确定和验证声明的噪声发射值。表 102 中的值适用： [外文原描述]： IEC 60704-2-3:2017 is intended to be used in conjunction with the 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. The relevant text of Part 1 as amended by this standard establishes the test code for dishwashers. This edition includes the following significant technical changes with respect to the previous edition: a) it doesn’t contain the description of an appropriate test enclosure because the test enclosure has been incorporated in IEC 60704-1:2010, Annex B; b) the values of standard deviations of sound power levels determined according to this part are given in Clause 1; c) to prevent an appliance being programmed to recognize the test cycles, and reacting specifically to them, in this new edition an artificial soil is used in addition to the unsoiled load and the rinse aid container has to be filled. This artificial soil successive may build up a film on the load. Therefore, detergent also has to be used. An initial test has shown that no foam is to be expected. This publication is to be read in conjunction with IEC 60704-1:2010 .
