Those interested in providing input on proposed changes to IIAR 8-201x, Decommissioning of Closed-Circuit Ammonia Refrigeration Systems, have until November 30 to submit comments.

As IIAR notes: "IIAR 8 specifies criteria for the decommissioning 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 are involved with the decommissioning of closed-circuit ammonia refrigeration systems. This standard shall apply only to closed-circuit mechanical refrigerating 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 or ASHRAE Standard 15). IIAR has designated the revised standard as BSR/IIAR 8-201x. Upon approval by the ANSI Board of Standards Review, the standard will receive a different name that reflects this approval date. "

The International Institute of Ammonia Refrigeration will use ANSI's consensus procedures to develop evidence of consensus among affected parties. To comment, visit IIAR's standards review web page for IIAR 8-201x to download a copy of the public review announcement and the draft standard. It also provides access to the online comment form.

To participate, submit all comments using the online form or via mail by November 30 at 5 p.m. ET.
