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, grasstrimmers,
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.
