BS EN ISO 22868:2021

This standard BS EN ISO 22868:2021 Forestry and gardening machinery. Noise test code for portable hand-held machines with internal combustion engine. Engineering method (Grade 2 accuracy) is classified in these ICS categories:

• 65.060.80 Forestry equipment
• 17.140.20 Noise emitted by machines and equipment
• 13.140 Noise with respect to human beings

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.
