Introducing IIAR’s newest ANSI approved Standard:

IIAR 6-2019

American National Standard for Inspection, Testing, and Maintenance of Closed-Circuit Ammonia Refrigeration Systems

IIAR 6 establishes the minimum requirements for inspection, testing, and maintenance (ITM) applicable to safe closed-circuit ammonia refrigeration systems. It is meant to aid in identifying what components should be inspected, tested, and maintained and how frequently these tasks should be performed. This standard is intended to be incorporated as part of a Mechanical Integrity (MI) Program as recognized and generally accepted good engineering practices (RAGAGEP). It can be used to perform a gap analysis for minimum safe requirements of an owner’s existing ITM tasks as well as provide the minimum requirements for ITM record keeping responsibilities.

Also introducing:

ANSI/IIAR 7-2019

Developing Operating Procedures for Closed-Circuit Ammonia Refrigeration Systems

In 2013, the first issue of IIAR 7 replaced the operations information contained in IIAR Bulletin No. 110, Guidelines for Start-Up, Inspection, and Maintenance of Ammonia Mechanical Refrigerating Systems.

This standard was first approved as an American National Standard by the American National Standards Institute (ANSI) in August 2013. ANSI requires reaffirmation or revision for periodic maintenance requirements of existing standards every five years. Work began on periodic maintenance of this standard in February 2017 and was completed in April 2019.

This standard defines the minimum requirements for developing operating procedures for closed-circuit ammonia refrigeration systems. Informative Appendix A was added to provide explanatory information related to provisions in the standard.
