A third public review of draft standard BSR/IIAR 2-201x, Standard for Safe Design of Closed-Circuit Ammonia Refrigeration Systems, is open. Interested parties can make comments on the draft standard, and substantive changes resulting from the public review will be provided for comment in a future public review (if necessary). Comments are due by December 29.
BSR/IIAR 2-201x specifies the minimum safety criteria for equipment and design of closed-circuit ammonia refrigeration systems. It presupposes that the persons who use the document have a working knowledge of the functionality of ammonia refrigerating systems and basic ammonia refrigerating practices and principles. The standard is intended for those who design ammonia refrigeration systems and only applies to closed-circuit mechanical refrigeration systems that utilize ammonia as the refrigerant. It supplements existing general refrigeration standards issued by IIAR and other organizations such as ASHRAE, ASME and ANSI.
