Laboratory Methods of Testing Air Circulating Fans for Rating and Certification
1. Purpose The purpose of this standard is to establish uniform methods for laboratory testing of air circulating fans to determine performance for rating or certification. 2. Scope This standard shall be used as the basis for testing electrically powered air circulating fan heads and ceiling fans when air is used as the test gas. The scope is limited to air circulating fans with an input power greater than or equal to 125 W—except for ceiling fans, which do not have a lower input power limit. The diameter of the fan being tested shall be limited by the minimum dimensions as shown in the applicable test figures. Exclusions: - Jet fans as defined in ANSI/AMCA Standard 214 - Powered roof ventilators, induced flow fans, laboratory exhausts - Positive pressure ventilators as defined in ANSI/AMCA Standard 240 - Compressors - Positive displacement machines Note: AMCA issued an errata for ANSI/AMCA 230-23 on 2023-10. Currently, the errata is placed at the end of the standard.
