标准范围

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林机械的常见噪声排放特性，以及链锯、灌木切割机、割草机、立边机、杆式动力修剪机的具体要求，树篱修剪机和花园吹风机/吸尘器/背包式喷雾机。噪声发射特性包括操作员位置的A加权发射声压级和A加权声功率级。本文件中所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。

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.
