It is now your chance to get your voice heard. Many good things have been accomplished by IIAR and the best practices they have produced over the last 50 years. IIAR 2 – The Safe Design of Closed-Circuit Ammonia Refrigeration Systems first published in 1974 had 210 base requirements. The most recent version of IIAR 2 has 758 base requirements. What will the 2020 version bring?
IIAR 2 specifies the minimum safety criteria for 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 system(s) and basic ammonia refrigerating practices and principles. This standard is intended for those who develop, define, implement and/or review the design of ammonia refrigeration systems. This standard shall apply only to closed-circuit refrigeration systems utilizing ammonia as the refrigerant. It is not intended to supplant existing safety codes (e.g., model mechanical or fire codes) where provisions in these may take precedence.
IIAR invites members to participate in the second (2nd) public review of BSR/IIAR 2-202x. IIAR will use the American National Standards Institute (ANSI) procedures to develop evidence of consensus among affected parties. ANSI’s role 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 BSR/IIAR 2-202x, and is responsible for the technical content of the standard.
Link for proposed draft and comments
The 45-day public review period will be from September 11, 2020 to October 26th, 2020. Comments are due no later than October 26th, 2020.
