IIAR Standards Suite Gets Update
IIAR-2 AMERICAN NATIONAL STANDARD FOR SAFE DESIGN OF CLOSED-CIRCUIT AMMONIA REFRIGERATION SYSTEMS:
There are two major changes being worked on to update IIAR-2, Czarnecki said. The first is Addendum A, which completes two tasks. Essentially, it takes all the information that needed to be addressed from ASHRAE 15 and places it in IIAR-2. Also, the language was cleaned up and clarified. Comments are being finalized from the second public review period, preparing for a limited third public review.
“It’s anticipated that sometime this fall, addendum A will be approved and published,” Czarnecki said. Additionally, headway is being made for the rewrite of the entire standard, set for publication in 2019. This will be an update to the original 2014 document and address any issues that have come up since its original publication.
The second item being updated is the corrosion element for vessels and other components in IIAR-2, Czarnecki said. The issue has drawn many viewpoints from within the industry, and Czarnecki said that committee worked to consider all perspectives. “The committee did take a vote on what would be included in the standard, and that’s being finalized. It’s basically a consensus vote.” The rewrite is part of IIAR’s five-year cycle program to update standards per ANSI guidelines.
“It’s anticipated that sometime this fall, IIAR-2 addendum A will be approved and published,” Czarnecki said. Additionally, headway is being made for the rewrite of the entire standard, set for publication in 2019. This will be an update to the original 2014 document and will address any issues that have come up since its original publication.”

IIAR-4 INSTALLATION OF CLOSED-CIRCUIT AMMONIA REFRIGERATION SYSTEMS:
Work on this standard is just getting underway, Czarnecki said. The standard is scheduled to be updated in 2020, but the subcommittee is acting now to get a jump start on the process. As work has just started, there isn’t much concrete information to report at this time, he said.
IIAR-5 START-UP AND COMMISSIONING OF CLOSED-CIRCUIT AMMONIA REFRIGERATION SYSTEMS:
This document’s scheduled Five-year update is complete, and comments are back from a pre-public informal review. “We’re ready to adjust the document for those comments,” Czarnecki said. “As a result, public review number one should be going out shortly.”
IAR-6 – STANDARD FOR INSPECTION, TESTING, AND MAINTENANCE OF CLOSED-CIRCUIT AMMONIA REFRIGERATION SYSTEMS:
IIAR-6 is a new document. It has been through two public reviews, and the comments from those reviews are now being considered so that the document can be updated and sent out for a third review process. “We have a strong desire to have this reach a conclusion by October,” Czarnecki said. “The schedule is important in order for the new standard to be recognized in the correct code body cycle. That’s a big deal.”
IIAR-7 DEVELOPING OPERATING PROCEDURES FOR CLOSED-CIRCUIT AMMONIA REFRIGERATION SYSTEMS:
The document’s scheduled five-year update is under way and although the standard will require a substantive change and a subsequent fourth public review process, Czarnecki said he is confident that it can be resolved relatively easily, concluding the scheduled update.
IIAR-9 RECOGNIZED AND GENERALLY ACCEPTED GOOD ENGINEERING PRACTICES (RAGAGEP) FOR EXISTING CLOSED-CIRCUIT AMMONIA:
This proposed standard is a new document. It aims to help companies decide whether or not their existing systems should be updated to reflect new requirements, according to IIAR materials.
It will provide a method for evaluating existing systems against requirements that should apply to all closed-circuit ammonia refrigeration systems regardless of age and will help determine what can or cannot be “grandfathered” regarding system design and regulatory compliance. This document has been through one public review, and the responses are currently being worked through, Czarnecki said. The goal is to have it finalized by the end of October However, since most documents go through three rounds of 30- to 45-day public review, the October deadline may be extended.
Czarnecki added that in October, IIAR will conduct a webinar for members, hosted by Tony Lundell, to present information about the changes in detail, giving members an opportunity to ask questions and provide feedback.
