IIAR safety standard for CO2 systems open for review

The International Institute of Ammonia Refrigeration (IIAR) has invited comments for the fourth public review of BSR/IIAR CO2-202x, Safety Standard for Closed-Circuit Carbon Dioxide Refrigeration Systems.

The public review period runs until March 14.

“Substantive changes resulting from this public review will also be provided for comment in a future public review if necessary,” the IIAR says.

“BSR/IIAR CO2-202x specifies the minimum requirements for safe design, installation, start-up, and inspection, testing, and maintenance (ITM) tasks applicable to stationary closed-circuit carbon dioxide refrigeration systems. It presupposes that the persons who use the document have a working knowledge of the functionality of carbon dioxide refrigeration system(s) and basic carbon dioxide refrigeration practices and principles.

“This standard is intended for those who design, install, start up, and inspect, test, and maintain stationary closed-circuit carbon dioxide refrigeration systems. This standard shall apply only to stationary closed-circuit refrigeration systems utilising carbon dioxide as the refrigerant. It supplements existing general refrigeration standards issued by the IIAR and other organisations such as ASHRAE, ASME, and ANSI. It is not intended to supplant existing safety codes (e.g., model mechanical or fire codes).”

The IIAR has designated the draft standard as BSR/IIAR CO2-202x. Upon approval by the ANSI Board of Standards Review, the standard will receive a different name that reflects this approval date.
