This European Standard was approved by CEN on 20 April 2022.
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this
European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references
concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN
member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by
translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management
Centre has the same status as the official versions.

1 Scope
This document provides basic requirements for piston type pneumatic linear actuators for industrial
valve, both double acting and single acting, used for on-off and modulating control duties.
It includes criteria, method and guidelines for design, qualification, corrosion protection, control and
testing.
It does not apply to diaphragm actuators and to pneumatic actuators which are integral parts of control
valves.
Other requirements, or conditions of use, different from those indicated in this document, are subject to
agreement, between the purchaser and the manufacturer/supplier, prior to order.
