Abstract

This Standard specifies the requirements and test methods for air admittance valves including those that are integral with a fixture trap.

Scope

This Standard specifies the requirements and test methods for air admittance valves including those that are integral to a fixture trap. This Standard does not cover air admittance valves for use where the air temperature is either below 0C or above 60C.
