Hydraulic fluid power. Determination of characteristics of motors - Startability best-seller • Routine and sample tests1 Scope This part of ISO 4392 specifies two test methods for determining the startability of rotary hydraulic motors. It describes two comparable methods of measurement, namely the constant torque method (see clause 6) and the constant pressure method (see clause 7). Since the results obtained by these two methods are equivalent, no preference is given to either. Additional physical quantities and their symbols are given in annex A. The accuracy of
