家用和类似用途电器.空气传播噪声测定的试验规程.第3部分:测定和验证公布噪声排放值的程序

[中文适用范围]： 本部分IEC 60704描述了确定和验证家用和类似电器噪声声明的程序。适用于IEC 60704-1和IEC 60704-2所有部分涵盖的所有类别的家用和类似电器。适用于批量生产的电器，如批次、系列或批次，这些电器按照相同的技术规范制造，并具有相同的噪声排放声明值。本部分IEC 60704考虑了“声明”术语，包括向潜在用户（消费者）提供噪声排放值的所有手段；这包括标签、宣传册、广告、商业和技术信息文件等；考虑了批量生产的电器的声明，批次具有相同的声明值；规定了一种简单的统计方法，通过仅调查三个电器的样本来验证声明值。 [外文原描述]： IEC 60704-3:2019 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 60704-3:2019 describes procedures for determining and verifying the declared values of the noise emitted by household and similar appliances. It applies to all categories of household and similar electrical appliances covered by IEC 60704-1 and all parts of IEC 60704-2, which include particular requirements for special categories of appliances. It applies to appliances being produced in quantity, such as in batches, series or lots, which are manufactured to the same technical specification and characterized by the same declared value of noise emission. This part of IEC 60704: – considers the term "declaration" to include all means for providing information on the noise emission values to potential users (consumers) of the appliances; this includes labels, brochures, advertisements, commercial and technical information papers, etc.; – considers the declaration for appliances manufactured by mass production; – specifies a simple statistical method for verifying the declared values by investigating a sample of only three appliances. This International Standard is to be used in conjunction with IEC 60704-1:2010 and the latest edition of IEC 60704-2 (all parts). This third edition cancels and replaces the second edition published in 2006. This edition constitutes a technical revision. It includes the following significant technical changes with respect to the previous edition: a) in Annex A, standard deviations that are now specified for various appliance categories in the parts of IEC 60704-2 have been excluded from Table A.1; b) furthermore, this edition makes reference to new standards and is implementing ISO/IEC Directives, Part 2 in a more accurate manner.
