Air Movement and Control Association (AMCA) International Inc. announces the publication of ANSI/AMCA Standard 320-23, Laboratory Method of Sound Testing of Fans Using Sound Intensity.
Superseding ANSI/AMCA Standard 320-08 (R2013), ANSI/AMCA Standard 320-23 contains extensive updates to reflect modern instrumentation and procedures and to clarify requirements that previously were subject to interpretation. Attempts were made to align the standard, to the extent practical and relevant, with AHRI 230, Sound Intensity Testing Procedures for Determining Sound Power of HVAC Equipment.
