Superseding ANSI/AMCA Standard 230-15, ANSI/AMCA Standard 230-23 establishes uniform methods of laboratory testing air-circulating fans to determine performance for rating or certification purposes. It applies to electrically powered air-circulating fan heads with an input power greater than or equal to 125 W and ceiling fans. Excluded are:

• Jet fans as defined in ANSI/AMCA Standard 214-21, Test Procedure for Calculating Fan Energy Index (FEI) for Commercial and Industrial Fans and Blowers.
• Powered roof ventilators, induced-flow fans, and laboratory exhaust fans.
• Positive-pressure ventilators as defined in ANSI/AMCA Standard 240-22, Laboratory Methods of Testing Positive Pressure Ventilators for Aerodynamic Performance Rating.
• Compressors.
• Positive-displacement machines.

ANSI/AMCA Standard 230-23 includes:

• Updated definitions related to air-circulating-fan classification.
• Revised classification of air-circulating fans into three product groups: unhoused air-circulating fan head, housed air-circulating fan head, and ceiling fan.
• Clarification on the use of fan outlet area as opposed to fan discharge area with housed air-circulating fans.
• The ceiling-fan-energy-index (CFEI) and thrust-efficiency-ratio metrics.
• Clarified procedures for measuring fan speed.
• 2021 errata to ANSI/AMCA Standard 230-15.
• Equations for calculating fan total pressure, which is required to calculate CFEI.
• A new annex (Annex C) defining subcategories of air-circulating fans.

Stakeholders for ANSI/AMCA Standard 230 are fan manufacturers, testing laboratories, fan engineers, fan-equipment specifiers, HVAC professionals, energy-efficiency regulators, utility-incentive-program developers, and building owners.

The cost of ANSI/AMCA Standard 230-23 is $45 for AMCA members and $90 for non-members in printed or PDF format and $61 for AMCA members and $122 for non-members in both printed and PDF formats. To purchase a copy, click here.
