ISO International Standard

ISO 22072:2011 defines the general characteristics, requirements and design data to be included in the procurement technical specification of an electrohydrostatic actuator (EHA) to be used to power aircraft control surfaces or other moving parts of an aerospace vehicle.

This type of actuator is an alternative to the hydraulically powered servo-control actuators that are currently used. It is intended that ISO 22072:2011 cover the unique requirements of EHAs.
