标准范围
This International Standard specifies the methods of determining the derived capacity of hydraulic fluid powerpositive displacement pumps and motors under steady-state conditions and at defined, continuous shaftrotational frequencies.Units can be tested as a positive displacement pump, with mechanical energy applied to the shaft and hydraulicenergy obtained at the outlet fluid connection, or as a motor, with hydraulic energy supplied to the inlet fluidconnection and mechanical energy obtained at the shaft.NOTE Measurement accuracy is divided into three classes A, B and C, which are explained in Annex A.
