标准范围

ISO/IEC 11553-3:2013描述了处理噪声危害的要求，并规定了在ISO/IEC 11553-1和ISO/IEC 11553-2范围内，在标准化条件下有效地确定、声明和验证激光加工机和手持式激光加工设备的空气噪声排放所需的所有信息。它规定了与噪音危害有关的安全要求。它规定了测试所用的噪声测量方法、安装和操作条件，以及此类设备制造商提供的信息。ISO/IEC 11553-3:2013适用于ISO/IEC 11553-1和ISO/IEC 11553范围内的激光加工机和手持式激光加工设备-2.噪声发射特性包括工作站的发射声压级和声功率级。公布的噪声排放值允许对市场上的激光加工机和手持式激光加工设备进行比较。使用本噪声测试规范（见附录A）可确保在特定限值内测定特征噪声排放值的再现性。这些限值由所用噪声排放测量方法的精度等级决定。ISO/IEC 11553-3:2013规定的噪声排放测量符合工程方法的要求（精度等级2）。

ISO/IEC 11553-3:2013 describes the requirements to deal with noise hazards and specifies all the information necessary to carry out efficiently and under standardized conditions the determination, declaration and verification of airborne noise emission from laser processing machines and hand-held laser processing devices within the scope of ISO/IEC 11553-1 and ISO/IEC 11553-2. It specifies the safety requirements relating to noise hazards. It specifies noise measurement methods, installation and operating conditions to be used for the test, together with the information to be supplied by manufacturers of such equipment.ISO/IEC 11553-3:2013 applies to those laser processing machines and hand-held laser processing devices included in the scope of ISO/IEC 11553-1 and ISO/IEC 11553-2.Noise emission characteristics include emission sound pressure levels at work stations and the sound power level. Declared noise emission values permit comparison of laser processing machines and hand-held laser processing devices on the market.The use of this noise test code (see Annex A) ensures the reproducibility of the determination of the characteristic noise emission values within specific limits. These limits are determined by the accuracy grade of the noise emission measuring method used. Noise emission measurements specified by ISO/IEC 11553-3:2013 meet the requirements of an engineering method (accuracy grade 2).
