Organization: ASHRAE
Publication Date: 24 June 2006
Status: active
Page Count: 16
scope:

This standard includes the specifications for test instruments, facilities, installations, and procedures and methods of calculation for determining aerodynamic performance and sound generation of air outlets and air inlets.

The test methods in this standard apply to both isothermal and non-isothermal conditions.

PURPOSE

The purpose of this standard is to define laboratory methods of testing air outlets and air inlets used to terminate ducted and unducted systems for distribution and return of building air.
