ARLINGTON HEIGHTS, Ill. - The Air Movement and Control Association International Inc. (AMCA) seeks public review and comment on two proposed American National Standards.

The first proposed standard, AMCA 510-03, establishes methods used in measuring performance of heavy-duty or severe service dampers, normally used in applications of elevated temperature, erosion, and/or corrosion conditions. This includes dampers that are used to control the flow of gas or to isolate one section of a duct system from another section of the same system.

The second proposed standard, AMCA 520-03, establishes an industry standard for testing actuators used on fire dampers. Requirements include torque or force rating, long-term holding, operational life, elevated temperature performance, periodic maintenance, production, and sound testing for both pneumatic and electric operators.

Interested parties should contact Timothy J. Orris, director of technical committees at 847-394-0150 or The deadline for comment is Aug. 24.
