本国家采用的国际标准为九个国际标准系列的使用提供了指导 描述确定所有类型机械声功率级的各种方法的标准 和设备。它提供:-这些基本国际标准的简要概述；-适用于任何特定类型的一个或多个标准的选择指南 （见第6条和附件D）。给出的指南仅适用于空气传播的声音。它是用于 噪声测试代码的编制（见ISO 12001）以及无特定噪声测试代码的噪声测试 存在。本国家采用的国际标准无意取代或添加任何 其他基本标准中单独试验方法的附加要求。

This Nationally Adopted International Standard gives guidance for the use of a series of nine International Standards describing various methods for determining the sound power levels from all types of machinery and equipment.It provides:- brief summaries of these basic International Standards;- guidance on the selection of one or more of these standards which are appropriate to any particular type (see clause 6 and annex D). The guidance given applies only to airborne sound. It is for use in the preparation of noise test codes (see ISO 12001) and also in noise testing where no specific noise test code exists.This Nationally Adopted International Standard is not intended to replace any of the details of, or add any additional requirements to, the individual test methods in the other basic standards referred to.
