Full Description
This part of ISO 10767 specifies a procedure for measuring the fluid pressure ripple characteristics of hydraulic fluid power pumps with a maximum error of +1 dB to 3 B.
ISO 10767-1 can be used if pressure ripple measurements at lower pressure levels, lower frequencies, or at greater accuracy levels is required. This procedure covers a frequency and pressure range that has been found to excite many circuits to emit airborne noise that most concerns designers of hydraulic fluid power systems. It allows the pressure ripple data to be published with minimal calculations and processing of the measured data. This part of ISO 10767 promotes quieter fluid power systems by establishing a uniform procedure for measuring and reporting the fluid pressure ripple characteristics of hydraulic fluid power pumps. Annex B contains a tutorial explanation of the technical basis for this test procedure.
