Purpose
This standard establishes uniform methods for laboratory testing of fans and other air moving devices to determine aerodynamic performance for rating or guarantee purposes in terms of airflow rate, pressure, power, air density, speed of rotation, and efficiency.
It is not the purpose of this standard to specify the testing procedures to be used for design, production, or field testing.
Scope
This standard may be used as the basis for testing fans, blowers, exhausters, compressors, or other air moving devices when air is used as the test gas.
The scope of this standard does not cover:
(a) circulating fans such as ceiling fans, desk fans and jet fans.
(b) compressors with interstage cooling.
(c) positive displacement machines.
(d) testing procedures to be used for design, production, or field testing.
The parties to a test for guarantee purposes may agree on exceptions to this standard in writing prior to the test. However, only tests which do not violate any mandatory requirements of this standard shall be designated as tests conducted in accordance with this standard.
