标准范围

ISO 22868:2011规定了一种噪声测试规范，用于在标准化条件下有效地测定便携式、手持式、内燃机驱动的林业和园艺机械的噪声排放特性，包括链锯、灌木切割机、割草机、杆式动力修剪机、树篱修剪机和花园鼓风机/吸尘器。噪声发射特性包括操作员位置的A加权发射声压级和A加权声功率级。

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.
