SCOPE
This standard describes 1-in. (25-mm) through 12-in. (300-mm) air valve and vent inflow preventer assemblies designed for use on the outlet of potable water distribution system air valves furnished in accordance with ANSI/AWWA C512 or storage facility vent pipes.

MAJOR REVISIONS
Major changes made to the standard in this edition include the following:
1. The definition of design pressure was added, to align with AWWA/ANSI C512 (Sec. 3).
2. Added PVC pipe as an option for an air supply line during flow and pressure verification testing (Sec. 5.1.3.1.1).
