This standard specifies methods for determining the performance and efficiency of hydraulic fluid power positive displacement pumps, motors and integral transmission. It applies to components having continuously rotating shafts. It also describes requirements for test installations, test procedures (under steady-state conditions) and the presentation of test results.
