Hydraulic fluid power. Determination of pressure ripple levels generated in systems and components - Method for motors Ingestion-build-258901 Basic test and measurement procedures1 Scope This part of ISO 10767 specifies a procedure for the determination of a rating of the source flow ripple, source impedance and pressure ripple levels generated by positive displacement hydraulic motors, including bi directional motors. Ratings are obtained as the following: a) the source flow ripple amplitude, in cubic metres per second, over ten individual harmonics of motoring frequency; b) the source impedance amplitude, in newton seconds
