ISO 22868:2011 specifies a noise test code for determining, efficiently and under standardized conditions, the noise emission characteristics of portable, hand‑held, combustion‑engine‑powered forestry and garden machines, including chain-saws, brush-cutters, grass-trimmers, pole-mounted powered pruners, hedge-trimmers and garden blowers/vacuums. Noise emission characteristics include the A‑weighted emission sound pressure level at the operator position and the A‑weighted sound power level.
