ANSI/ASHRAE Standard 113-2005, which supersedes ANSI/ASHRAE Standard 113-1990, defines 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 condition.

This Standard:

• Specifies equipment and procedures for measuring air speed and air temperature in occupied zones of building spaces.
• Applies to furnished or unfurnished spaces with or without occupants
• Applies to air distributions systems, including systems in which air outlets are located inside and outside, or outside of the occupied zone; and in which local air velocities in the occupied zones are or are not under control by individual occupants.
