适用范围: 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.
