ARLINGTON HEIGHTS, Ill., 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.

This 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 standardized design data for the application of LDCF in occupied spaces.

Currently, each LDCF manufacturer uses a different method of test. 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). A method of test is needed to provide consistent, accurate, comparable sound performance data for designers and end-users.

Committee members would be expected to participate in reviewing the standard and resolving any comments received. Meetings will be held virtually by conference call.

Stakeholders for the Standard include manufacturers of LDCF, Building Design Engineers and Architects, end-users, testing labs of LDCF, and associations within the HVAC industry (trade associations and professional societies).

To volunteer, click here and complete and submit the form by the close of business on 17 November 2021. For more information, contact Shruti Kohli-Bhargava, Manager, Publications & Standards at [email protected].
