IEC 60704-2-3:20 17旨在与IEC 60704-1第三版（2010）家用和类似用途电器—空气传播声噪声测定的试验规范—第1部分:一般要求结合使用。 经本标准修订的第1部分的相关文本建立了洗碗机的测试规范。 与上一版相比，此版本包括以下重大技术变更: a)它不包含适当测试外壳的描述，因为测试外壳已纳入IEC 60704-1:20 10附录B； b)根据本部确定的声功率级的标准偏差值在第1条中给出； c)为了防止设备被编程为识别测试循环并对其做出特定反应，在该新版本中，除了未弄脏的负载之外，还使用了人造污垢，并且必须填充漂洗助剂容器。这种人造土壤可能会在负载上形成薄膜。因此，还必须使用洗涤剂。初步测试表明，预计不会产生泡沫。 本出版物应与IEC 60704-1:20 10一起阅读。

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.
