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.

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 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.

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 7-2013 Developing Operating Procedures for Closed-Circuit Ammonia Mechanical Refrigerating

ANSI/IIAR 7-2013 defines the minimum requirements for developing operating procedures for closed-circuit ammonia mechanical refrigerating systems. The operating procedures were developed to be easy to understand, safe, effective, reliable, and to meet applicable regulatory environments. This standard is intended for those who develop, define, and/or review operating procedures for ammonia refrigeration systems.
