The Board of Standards Review for the American National Standards Institute (ANSI) has approved and recognized ARI Standards 580-2001, "Non-Condensable Gas purge Equipment For use With Low Pressure Centrifugal Liquid Chillers," and 1060-2001, "Rating Air-To-Air Heat Exchangers For Energy Recovery Ventilation Equipment," as American National Standards. ARI Standard 580-2001, from the Air-Conditioning and Refrigeration Institute (ARI), applies to non-condensable gas purge equipment for use with low pressure centrifugal liquid chillers. ARI Standard 1060-2001, also from ARI, applies to factory-made air-to-air heat exchangers for use in energy recovery ventilation equipment. "ARI’s development and publication of standards and guidelines are among our most important functions," says Michele Darbeau, ARI’s Standards Engineer. "Adding the ANSI approval logo and the American National Standard designation to ARI Standards 390-2001 and 1060-2001 ensures a balanced, consensus standards development process that benefits our members and is in the public interest." ARI standards establish rating criteria and procedures for measuring and certifying product performance. In this way, products are rated on a uniform basis so that buyers and users can properly make selections for specific applications. ANSI, a private, non-profit organization that administers and coordinates the U.S. voluntary standardization and conformity assessment system, currently provides a forum for over 270 ANSI-accredited standards developers representing approximately 200 distinct organizations in the private and public sectors. These groups work cooperatively to develop voluntary national consensus standards and American National Standards (ANS). In 2001, there were approximately 11,500 such documents. The ANSI letter ballot or "canvass" method under which ARI is accredited serves many standardization efforts in the United States by providing and promoting a process that verifies that the principles of openness and due process have been followed in the approval procedure. The ANSI canvass method also ensures that a consensus of those individuals who are directly and materially affected by the standards has been achieved. Individuals interested in becoming a reviewer for any ARI Standard undergoing ANSI canvassing are encouraged to participate by contacting Michael Woodford, ARI's assistant vice president of Engineering and Research, at For a free copy of ARI Standards 580-2001 and/or 1060-2001, visit "CoolNet," ARI’s Web site, at, or contact Michele Darbeau, ARI’s Standards Engineer, at
