Any person performing tests in accordance with thisInternational Standard shall be appropriately trained in the type of work to be carried out.This International Standard specifies a noise test code for determining, efficiently and under standardizedconditions, the noise emission characteristics of portable, hand-held, combustion-engine-powered forest andgarden machines, including chain-saws, brush-cutters, grass-trimmers, pole-mounted powered pruners,hedge-trimmers and garden blowers/vacuums. Noise emission characteristics include the A-weightedemission sound pressure level at the operator position and the A-weighted sound power level.
