ISO 18170:2017 establishes the general requirements for electric motor driven, variable delivery, hydraulic pumps suitable for use in aircraft hydraulic systems.

ISO 18170:2017 includes the general requirements for Alternating Current (AC) induction electric motor powered units. The AC power electrical power supply can be either controlled to provide a Constant Frequency (CF) or uncontrolled to provide a Variable Frequency (VF) AC supply to the electric motor.

ISO 18170:2017 is intended to be used in conjunction with the detail specification that is particular to each application.
