IIAR 2-2014, Addendum A Third Public Review

The IIAR has announced a 3rd Public Review of Standard BSR/IIAR 2-2014, Addendum A, Standard for Safe design of Closed-Circuit Ammonia Refrigeration Systems. This brings some interesting changes to IIAR 2 . Two of these proposed changes are :

  1. Clearing up the “corrosion allowance” debate in a way that most reasonable people can live with.
  2. Clearing up the NH3 detection requirements – mostly by moving Level 2 & 3 to the informative appendix.

A third (3rd) 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 third (3rd) 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.

The 30-day public review period will be from October 5, 2018 to November 4, 2018. Comments are due no later than November 4, 2018.

Thank you for your interest in the public review of BSR/IIAR 2-2014, Addendum A, Standard for Safe Design of Closed-Circuit Ammonia Refrigeration Systems.
