The International Institute of Ammonia Refrigeration (IIAR) is proposing to revise ANSI/IIAR 2-1999, “American National Standard for Equipment, Design, and Installation of Ammonia Mechanical Refrigerating Systems”. This standard is a guide to the design, manufacture, installation, and use of ammonia mechanical refrigerating systems in industrial occupancies. IIAR has designated the proposed revision as BSR/IIAR 2-1999R. Following approval by IIAR and the ANSI Board of Standards Review (BSR), the revised standard will be published with a new designation.

The role of the American National Standards Institute (ANSI) in the revision process is to establish and enforce standards of openness, balance, due process, and harmonization with other American and international standards. IIAR is the ANSI-accredited standards developer for ANSI/IIAR 2, and is responsible for technical content of the standard.

You are invited to participate in the public review of the proposed revisions to ANSI/IIAR 2-1999. The public review will be conducted from April 4, 2008 to May 4, 2008. Comments must be received the International Institute of Ammonia Refrigeration (IIAR) by 5:00 pm Eastern Standard Time on May 4th. Click on the following links to connect to:
