Laboratory Methods of Testing Air Circulating Fans for Rating and Certification
|Publication Date:||1 January 2015|
This standard shall be used as the basis for testing air circulating fan heads, ceiling fans, box fans, table fans, portable personnel coolers or other air circulating devices when air is used as the test gas. The diameter of the fan being tested shall be limited by the minimum dimensions as shown in the applicable test figures.
Blowers, exhausters, compressors, positive displacement machines and positive pressure ventilators are not within the scope of this standard.
The parties to a test for guarantee purposes shall 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.
The purpose of this standard is to establish uniform methods for laboratory testing of air circulating fans to determine performance (forward or reverse flow) in terms of airflow rate for rating, certification or guarantee purposes.
