Re: First (1st) Public Review of IIAR 5-202x, Startup of Closed-Circuit Ammonia Refrigeration Systems

A first (1st) public review of draft standard IIAR 5-202x, Startup of Closed-Circuit Ammonia Refrigeration Systems is now open. The International Institute of All-Natural 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.

IIAR 5-202x, defines the minimum requirements for startup of closed-circuit ammonia refrigeration systems. It presupposes that the persons who use the document have a working knowledge of the functionality of an ammonia refrigeration system(s) and basic ammonia refrigeration practices and principles. This standard is intended for those who startup closed-circuit ammonia refrigeration systems. This standard shall apply only to stationary 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 draft standard as IIAR 5-202x. 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 first (1st) public review of IIAR 5-202x. 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 IIAR 5-202x, and is responsible for the technical content of the standard.

The 45-day public review period will be from April 12th, 2024 through May 27th, 2024. Comments are due no later than 5:00 pm Eastern Standard Time (EST) on May 27th, 2024.

Thank you for your interest in the public review of IIAR 5-202x, Startup of Closed-Circuit Ammonia Refrigeration Systems.
