scope:

This standard specifies equipment and procedures for measuring air speed and air temperature in occupied zones of building spaces.

This standard applies to furnished or unfurnished spaces (actual or mock-up), with or without occupants.

This standard applies to air distribution systems, including systems in which

a. air outlets are located inside, inside and outside, or outside of the occupied zone and

b. local air velocities in the occupied zone are or are not under control by individual occupants.

This standard does not cover

a. rating of individual air outlets and inlets or

b. naturally ventilated building spaces.

PURPOSE

The purpose of this standard is to define a repeatable method of testing the steady-state air diffusion performance of an air distribution system in occupied zones of building spaces. This method is based on air velocity and air temperature distributions at specified heating or cooling loads and operating conditions.
