Scope

This document describes the measurement specifications for effectively determining the common noise emission characteristics of portable hand-operated forestry and gardening machinery powered by internal combustion engines under standardized conditions, as well as the specific requirements for chainsaws, brushcutters, lawn mowers, edgers, pole pruning saws, hedge trimmers, and garden blowers/vacuum cleaners/backpack sprayers. The noise emission characteristics include the A-weighted sound pressure level and A-weighted sound power level at the operator's position.
The noise measurement specifications described in this document help manufacturers verify the effectiveness of low-noise designs.
