ASHRAE Standard 130-2016 Laboratory Methods of Testing Air Terminal Units
ASHRAE Standard 130-2016 Laboratory Methods of Testing Air Terminal Units specifies instrumentation, test installation methods, and procedures for measuring the capacity and related performance of constant-volume, variable-volume, and modulating integral diffuser air terminals.
The 2016 revision of the standard includes updates and revisions to all parts of the standard, including its title, purpose, and scope. It updates definitions, redefines airflow sensor performance testing, and adds a method to determine terminal-unit total pressure loss coefficients and the relationship between terminal-unit casing leakage and pressure.
The methods of test in this standard apply to air control devices used in air distribution systems. These devices provide control of air volume with or without temperature by one or more of the following means and may or may not include a fan:
a. Fixed or adjustable directional vanes (i.e., bypass terminal)
b. Pressure-dependent volume dampers or valves (including
air induction nozzles and dampers)
c. Pressure-independent volume dampers or valves (including
air induction nozzles and dampers)
d. Integral heat exchanger
e. On/off fan control
f. Variable-speed fan control
g. Modulating integral diffuser terminals

a. Sound power
b. Temperature mixing and stratification
c. Minimum operating pressure
d. Air leakage
e. Induced airflow
f. Fan airflow
g. Fan motor electrical power
h. Condensation
i. Airflow sensor performan
