ASHRAE AMCA 51-2016

This standard establishes uniform test methods for a laboratory test of a fan or other air moving device to determine its aerodynamic performance in terms of airflow rate, pressure developed, power consumption, air density, speed of rotation and efficiency for rating or guarantee purposes. This standard applies to a fan or other air moving device when air is used as the test gas, with the following exceptions: (a) air circulating fans (ceiling fans, desk fans);(b) positive pressure ventilators;(c) compressors with interstage cooling;(d) positive displacement machines; and(e) test procedures to be used for design, production or field testing.
