scope:
This Standard specifies methods for measuring the A-weight sound pressure levels at prescribed microphone positions in the proximity of the machine under test while the machine is stationary or in motion. From these values the A-weighted sound power level of the machine may be calculated. It defines acoustical requirements for measurements in an essentially free field over a partially reflecting plane, covered with a specified official absorbing material or natural grass. The operating and mounting conditions of the machine under test are described in detail.
