CSA Group Hydraulic fluid power - Electrically controlled hydraulic pumps - Test methods to determine performance characteristics ISO 17559:2003

ISO 17599:2003 specifies methods for determining the steady-state performance characteristics and dynamic performance characteristics of positive-displacemen t electrically and electronically controlled hydraulic pumps, so as to allow comparison of the performance of different components. Pumps covered by ISO 17599:2003 have the capacity to affect changes in the output flow or pressure in proportion to the electrical or electronic input signals. These pumps can be of the load-sensing control type, servo-control type, or electrical variable displacement mechanism type, which control output flow and output pressure by feedback using electrical signals.
