This Aerospace Recommended Practice (ARP) defines tests to be performed on hydraulically@ electrically@ pneumatically@ and mechanically actuated air valves. They may be further defined as those valves that function in response to externally applied forces or in response to variations in upstream and/or downstream duct air conditions in order to maintain a calibrated duct air condition (e.g.@ air flow@ air pressure@ air temperature@ air pressure ratio@ or air shutoff). Purpose: The purpose of this ARP is to provide the aircraft industry with a guide for laboratory qualification testing of aircraft air valves.
