DIN EN ISO 22868-2011 林业和园林机械.带内燃机的便携手持式机械的噪声试验规范.工程法(2级准确度)(ISO 22868-2011);德文版本EN ISO 22868-2011
Forestry and garden machinery - Noise test code for portable hand-held machines with internal combustion engine - Engineering method (Grade 2 accuracy) (ISO 22868:2011); German version EN ISO 22868:2011
This International Standard specifies a noise test code for determining, efficiently and under standardized conditions, the noise emission characteristics of portable hand-held, combustion engine powered forest machines such as chain saws, brush-cutters, grass trimmers, pole-mounted powered pruners, hedge trimmers and garden blowers. Noise emission characteristics include the A-weighted emission sound pressure level at the operator position and the A-weighted sound power level.
