PurposeThis 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.ScopeThis 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.
