Purpose and Scope

The purpose of this standard is to establish a uniform laboratory method for determining an induced flow fan's aerodynamic performance in terms of airflow rate, pressure developed, power consumption, air density, speed of rotation and efficiency. This standard is an adjunct to ANSI/AMCA 210 in order to accommodate the induced flow fan's unique characteristics.

It is not the purpose of this standard to specify the testing procedures to be used for design, production or field testing.

The scope of this standard is limited to induced flow fans, as defined below.

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.
