This recommended practice provides a method of characterizing Electrohydrostatic Actuator (EHA)/Electrohydrostatic Module (EHM) duty cycles for the following purposes:
a. To enable the comparison of the severity of different EHA/EHM applications. This allows the use of previously qualified designs without the need for repeat testing.
b. To define parameters for endurance-test design of EHAs; e.g., a way of executing a life-equivalent test in a shorter duration by increasing the speed of cycles and/or the level of applied loads.
