IIAR Standards Review

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 as 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.

We invite you to participate in all public reviews.  IIAR will use the American National Standards Institute (ANSI) procedures to develop evidence of consensus among affected parties.  ANSI's role in the revision process is to establish and enforce standards of openness, balance, due process and harmonization with other American and International Standards.  IIAR is an ANSI accredited standards developer and is responsible for the technical content in all IIAR Standards.
