Part 2 describes a method for determining mean sound level and mean band pressure level of airborne sound emitted by pneumatic tools and machines, including both percussive machines, such as crawler drills, rock drills, paving breakers, picks and spaders, chippers, riveters, scalers, and non-percussive machines, such as rotary air machines, screw drivers and nut setters, impact wrenches, hoists. It is an engineering method which requires a controlled environment for repeatable results.

This standard describes a method for determining the mean sound level and mean band pressure level of airborne sound emitted by pneumatic tools and machines. These include both percussive machines (such as crawler drills, rock drills, paving breakers, picks and spaders, chippers, riveters, scalers, spike and pin drivers, rammers and tampers) and non-percussive machines (such as rotary air machines, screw drivers and nut setters, impact wrenches and hoists). This is an engineering method in which care is required to establish a controlled environment in order to achieve repeatable results.
