This standard covers the development of specifications@ minimum design requirements and sizing criteria for electric actuators. This standard is not intended to address the range of compact@ light duty low torque electric actuators typically rated for less than 5.65 Nm (50 in-lbs)@ and it is not intended for electrically powered actuators that use hydraulic fluid for power transmission (refer to ANSI/ISA-96.06.01). Purpose The purpose of this standard is to provide a guide to assist the user in specifying electric valve actuators.
