Hydraulic fluid power. Determination of characteristics of motors - At constant low speed and constant pressure Ingestion-build-146508 Operating conditions1 Scope This part of ISO 4392 describes a method of determining the low speed characteristics of positive displacement rotary fluid power motors, of either fixed or variable displacement types. The method involves testing at slow speeds which may generate frequencies having a significant influence upon the steady continuous torque output of the motor and affect the system to which the motor would be connected. The accuracy of measurement is divided
