本国际标准是框架标准，介绍了基本组ISO 11201、ISO 11202、ISO 11203、ISO 11204和ISO 11205，用于确定工作站和其他指定位置的发射声压级。它为以下方面提供了指导: -促进噪声测试代码的编写提供该噪声排放量与其他噪声量的物理解释（见4.1至4.3）；-比较小组提供的不同测量方法（见表1）；-促进在典型实际情况下选择最合适的方法（第6条）。 本国际标准主要基于流程图和表格。描述了案例研究。 给出的指南仅适用于空气传播的声音。它一般用于噪声测试，特别是用于编制噪声测试代码。 标准化噪声测试代码旨在从ISO 11201、ISO 11202、ISO 11203、ISO 11204和ISO 11205组中选择最适合其涵盖的机械系列的标准，并给出特定系列的安装和操作条件的详细要求，以及这些国际标准中规定的工作站和其他指定位置的位置。 由此获得的数据可用于声明和验证发射声压级，例如ISO 4871中的规定。[3] 交叉引用:IEC 60942ISO 3747:1995ISO 9614-3ISO 3745ISO 11204:2010ISO 9614-1ISO 3743-1ISO 9614-2IEC 61672-1ISO 11201:2010IEC 61260ISO 11202:2010IEC 61043ISO 3746ISO/IEC指南98-3:2008ISO 3744ISO 11205:2003ISO 11203:1995ISO 3743-2:2018ISO 3741ISO 4871ISO 12001ISO 3740ISO 9612TR 11690- 3 ISO 1996-1包含以下内容:修订版，2020年2月

This International Standard is the frame standard introducing the basic group, ISO 11201, ISO 11202, ISO 11203, ISO 11204 and ISO 11205, on the determination of emission sound pressure levels at work stations and other specified positions. It gives guidance for: — facilitating the writing of noise test codes;— providing physical explanations of this noise emission quantity compared to other noise quantities (see 4.1 to 4.3);— comparing the different measurement methods offered by the group (see Table 1);— facilitating the choice of the most appropriate method(s) in typical practical situations (Clause 6). This International Standard is largely based on flow charts and tables. Case studies are described. The guidance given applies to airborne sound only. It is for use in noise testing, in general, and in the preparation of noise test codes, in particular. A standardized noise test code is intended to select standards from the ISO 11201, ISO 11202, ISO 11203, ISO 11204 and ISO 11205 group, which are the most appropriate to the machinery family it covers, and which give detailed requirements on mounting and operating conditions for the particular family, as well as the location of the work station(s) and other specified positions as prescribed in these International Standards. The data so obtained can be used for the declaration and verification of emission sound pressure levels, e.g. as specified in ISO 4871.[3]Cross References:IEC 60942ISO 3747GUM:1995ISO 9614-3ISO 3745ISO 11204:2010ISO 9614-1ISO 3743-1ISO 9614-2IEC 61672-1ISO 11201:2010IEC 61260ISO 11202:2010IEC 61043ISO 3746ISO/IEC Guide 98-3:2008ISO 3744ISO 11205:2003ISO 11203:1995ISO 3743-2:2018ISO 3741ISO 4871ISO 12001ISO 3740ISO 9612TR 11690-3ISO 1996-1Incorporates the following:Amendment, February 2020
