The noise measurement methods specified in this standard are mainly applicable to rock drilling machinery and pneumatic tools (hereinafter referred to as machines) powered by compressed air. Rock drilling machinery using other power sources can also be implemented in accordance with this standard. Typical machines for which this standard applies include: rock drills (e.g., hand-held, air-leg rock drills), drill rigs, impact breakers, air picks, air shovels, air spades, tamping machines, riveters, rust removers, nailers Machines, air grinding wheels, air drills, air triggers, tapping machines, air screwdrivers, air scissors, air saws, air motors, air pumps, and air cranes. If there are special requirements for the noise measurement of certain products, they shall be specified in the product standards. This standard does not apply to machines that radiate isolated bursts of sound and machines that have a repetition rate of less than 10 pulses per second. Note: When the difference between the readings of the "slow" gear and the "pulse" gear of the sound level meter is greater than 5dB at the same microphone position, this noise can be considered as impulse noise.
