IIAR Standards

IIAR Standards contain both normative and informative information, establishing both the minimum requirements for industry compliance and advisory information where applicable.  IIAR Standards are ANSI approved so they are subject to a rigorous public review process to ensure that they represent an industry consensus.  IIAR Standards set the industry standard and are a must-have technical resource to ensure a safe and efficient industrial refrigeration operating environment. For more information on IIAR Standards click here. 

Currently, the Standards offered below are only available in a print edition. We at IIAR are working on offering digital versions of our Standards for purchase. Thank you for your patience.

ANSI/IIAR Standard 1-2017 American National Standard for Definitions and Terminology Used in IIAR Standards

ANSI/IIAR 1-2017 provides a unified set of definitions for use in the IIAR Standards. A set of common definitions is provided to prevent confusion among engineers, contractors and jurisdictional authorities. The definitions provided in this Standard apply to the defined terms whenever they are used in any one of the Standards in the ANSI/IIAR Standards.

ANSI/IIAR 2-2014, Addendum A, American National Standard for Safe Design of Closed-Circuit Ammonia Refrigeration Systems
The new and improved IIAR 2 is the definitive design safety standard of the ammonia refrigeration industry - IIAR 2 has undergone extensive revision since the 2008 (with Addendum B) edition was published on December 3, 2012. A major focus of changes made to this edition has been incorporating topics traditionally addressed in other codes and standards so that IIAR 2 can eventually serve as a single, comprehensive standard covering safe design of closed-circuit ammonia refrigeration systems.

Addendum A (2019) has been published to address concerns raised by interpretation requests, and to address some differences with other published refrigeration design standards. In addition to these changes, a new chapter (18) and a new appendix (N) were added to address ammonia absorption systems. The former appendix N information (references) has been moved to appendix O. Sections that have been changed or are new for Addendum A are marked with a line in the margin.

ANSI/IIAR Standard 3-2017 American National Standard for Ammonia Refrigeration Valves
ANSI/IIAR Standard 3-2017 specifies criteria for materials, design parameters, marking and testing of valves and strainers used in closed circuit ammonia refrigeration systems. This standard is not intended to supplant existing safety codes. In cases where the authority with jurisdiction has special requirements that are more stringent than those in the standard, that authority shall prevail.

ANSI/IIAR Standard 5-2019 American National Standard for the Startup of Closed-Circuit Ammonia Refrigeration Systems
ANSI/IIAR 5 specifies criteria and procedures of the startup and commissioning of closed-circuit ammonia mechanical refrigeration systems. It provides basic minimum requirements for the safe start-up and commissioning of completed closed-circuit mechanical refrigerating systems utilizing ammonia as the refrigerant and additions and modifications made to such systems.

ANSI/IIAR 5-2019 was reaffirmed and approved by ANSI September 9th, 2019 which supersedes ANSI/IIAR 5-2013

Informative Appendix A was added to provide explanatory information related to provisions in the standard. Sections of the standard with associated explanatory information are marked as an asterisk “*” after the section number, and the associated appendix information is located in Appendix A with a corresponding section number preceded by “A”.

ANSI/IIAR Standard 6-2019 American National Standard for the 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 system. 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.
