Scope

GB/T 23282-2009 is the English-translated version of 锻压机械噪声声功率级测量方法.

GB/T 23282-2009 — This standard specifies the sound pressure level measured at the upper envelope forging machinery measuring surface sound source to calculate the forging machinery sound power level of the party law.

Also given acoustic environment, and the use of measuring instruments and the calculation of surface sound pressure level and sound power level.

The method specified in this standard apply only to the actions specified in a "steady state" and "unsteady" forging machinery noise measurement specification without when applied to a predetermined action norms radiation forging machinery noise measurement "pulse" noise.

Having a reflective surface suitable for regulatory compliance Given the requirements of indoor and outdoor environments. NOTE. Noise Classification (steady, non-steady-state, quasi-steady state, pulse, etc.) see GB/T 14259.

What this standard covers

This standard specifies the measurement of sound pressure level in the envelope forging machinery for measuring surface sound source to calculate forging machinery sound power level approach. Also given acoustic environment, measuring instruments and methods of computation and use of surface sound pressure level and sound power level. This standard specifies the method applies only to the specified action when the specification is "steady state" and "non- steady state" of forging machinery noise measurements, does not apply to the specified action when the specification is radiation " pulse" of forging machinery noise noise measurement. Compliance with applicable requirements of a reflective surface indoor and outdoor environments.
