适用范围：This part of ISO 4412 establishes a test code de-scribing procedures, based on ISO 2204, for the de-termination of the sound power levels of a hydraulic fluid power pump, under controlled conditions of in-stallation and operation, suitable for providing a ba-sis for comparing the noise levels of pumps in terms of: — A-weighted sound power level; — octave band sound power levels. From these sound power levels, if required, refer-ence sound pressure levels may be calculated for reporting purposes in accordance with annex A. For general purposes, the frequency range of inter-est includes the octave bands with centre fre-quencies between 125 Hz and 8 000 Hz.
