ISO 4409:2007 Hydraulic fluid power - Positive-displacement pumps, motors and integral transmissions - Methods of testing and presenting basic steady state performance
This International Standard specifies methods for determining the performance and efficiency of hydraulic fluid
power positive displacement pumps, motors and integral transmissions. It applies to components having
continuously rotating shafts.
This International Standard specifies the requirements for test installations, test procedures under steadystate
conditions and the presentation of test results.
