标准摘要
[中文适用范围]： 本文件规定了噪声测试规范，用于在标准化条件下有效地确定便携式、手持式、内燃机驱动的森林和园艺机械的常见噪声排放特性，以及链锯、割灌机、割草机、修边机、杆式动力修枝机、绿篱机和花园吹风机/吸尘器/背负式喷雾器。 噪声发射特性包括操作员位置处的 A 计权发射声压级和 A 计权声功率级。 本文档中描述的噪声测试代码使制造商能够验证低噪声设计方面的工作。 [外文原描述]： This document specifies a noise test code for determining, efficiently and under standardized conditions, the common noise emission characteristics of portable, hand-held, combustion engine powered forest and garden machines, and specific requirements for chain-saws, brush-cutters, grass-trimmers, edgers, pole-mounted powered pruners, hedge-trimmers and garden blowers/vacuums/knapsack mist blowers. Noise emission characteristics include the A-weighted emission sound pressure level at the operator position and the A-weighted sound power level. Noise test codes as described in this document enable the manufacturer to verify the effort regarding low noise design.
