Re: Second (2nd) Public Review of Standard BSR/IIAR 2-2014, Addendum A, Standard for Safe design of Closed-Circuit Ammonia Refrigeration Systems.

A second (2nd) public review of draft standard BSR/IIAR 2-2014 Addendum A, Standard for Safe Design of Closed-Circuit Ammonia Refrigeration Systems is now open. The International Institute of Ammonia Refrigeration (IIAR) invites you to make comments on the draft standard. Substantive changes resulting from this public review will also be provided for comment in a future public review if necessary.

BSR/IIAR 2-2014, Addendum A 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 supplements existing general refrigeration standards issued by IIAR and other organizations such as ASHRAE, ASME, and ANSI. It is not intended to supplant existing safety codes (e.g., model mechanical or fire codes).

IIAR has designated the revised standard as BSR/IIAR 2-2014, Addendum A. Upon approval by the ANSI Board of Standards Review, the standard will receive a different name that reflects this approval date.

We invite you to participate in the second (2nd) public review of BSR/IIAR 2-2014, Addendum A. 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 2-2014, Addendum A, and is responsible for the technical content of the standard.
