AMCA initiates work on Standard 340

ARLINGTON HEIGHTS, Illinois, United States, 18 October 2021: Air Movement and Control Association (AMCA) International Inc. is seeking volunteers to serve on the technical committee for a new AMCA Standard: AMCA Standard 340 – Laboratory Method of Sound Testing of Large-Diameter Ceiling Fans.

Making the announcement through a Press release, AMCA said the standard will develop a method of sound testing for large-diameter ceiling fans (LDCF), sometimes referred to as High Volume Low Speed, or HVLS, fans. The method would allow for the third-party certification of sound data in a manner that is cost-effective and produces accurate, repeatable results, and to provide standardised design data for the application of LDCF in occupied spaces, AMCA added.

​Currently, each LDCF manufacturer uses a different method of test, AMCA said. Existing sound test standards require acoustical testing chambers that are cost-prohibitive due to the large size of LDCF – up to 24 feet in diameter, AMCA said. A method of test is needed to provide consistent, accurate and comparable sound performance data for designers and end-users, AMCA added.

Committee members would be expected to participate in reviewing the standard and resolving any comments received, AMCA said, adding that meetings will be held virtually by conference call.

According to AMCA, stakeholders for the Standard include manufacturers of LDCF, building design engineers and architects, end-users, testing labs of LDCF, and trade associations and professional societies within the HVAC industry.​

AMCA invited those interested in volunteering to click here and complete and submit the form by the close of business on November 17. For more information, it encouraged those interested to contact Shruti Kohli-Bhargava, Manager, Publications & Standards at shrutik@amca.org.
