A second (2nd) public review of draft standard BSR/IIAR CO2-202x, Safety Standard for Closed-Circuit Carbon Dioxide Refrigeration Systems is now open. At that link one can comment to the material in this proposed standard. 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 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 utilizing carbon dioxide 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).
