Scope
This standard specifies the method for measuring the A-weighted sound level of casting machines with standard radiation steady-state noise, radiation non-steady-state noise, and radiation periodic change noise. The frequency-band sound pressure level can also be measured according to this method.
This standard is applicable to the noise measurement of all types of casting machines.
