ARLINGTON HEIGHTS, Ill. — The Air Movement and Control Association (AMCA) International Inc. is seeking volunteers to serve on a technical committee that will review and update ANSI/AMCA Standard 500-D, “Laboratory Methods of Testing Dampers for Rating.”

ANSI/AMCA Standard 500-D establishes uniform laboratory methods for evaluating the performance of dampers in terms of air leakage, pressure drop, dynamic closure, operational torque, and more.

Both committee and non-voting members are sought. A committee member is someone directly or materially affected by the subject of a standard. A non-voting member receives all materials (agendas, minutes, committee drafts, etc.) distributed to committee members and may join conference calls but cannot vote.

Committee members will be expected to participate in review, drafting, and the resolution of any and all comments until the revised standard is approved, a press release from AMCA said. Most, and possibly all, meetings will be held virtually using Microsoft Teams.

If you are interested in serving on the technical committee for ANSI/AMCA Standard 500-D, click here and complete and submit the form by Friday, Aug. 2.
