AHRI Standards
AHRI Standards Overview

AHRI standards are developed under a process composed of multiple levels of development, review, and approval by industry experts and other stakeholders. The AHRI standards process is accredited by both the American National Standards Institute (ANSI) and Standards Council Canada (SCC), which means that AHRI standards can be further approved as American National Standards (ANS) and/or as National Standards of Canada (NSC).

The stages of development and approval include the following:

  1. A proposal to start a new activity coming from any source.
  2. Initiation of a standards activity by the Standards Subcommittee.
  3. Development of a draft by the Standards Technical Committee or Standards Work Group.
  4. Public review of the draft, then revision by the Standards Technical Committee to address comments received and approval by the Standards Technical Committee.
  5. Review and approval of the draft by the Standards Subcommittee. The document may now be published as an AHRI standard.
  6. (Optionally) Review and approval by a Consensus Body and submission by AHRI staff to ANSI and/or SCC for publication of the AHRI standard as American National Standard (ANS) and/or National Standard Canada (NSC)

Appeals
Appeals related to any decisions made, or actions taken or not taken, are handled in accordance with the appeals process found in section 6.9 of the AHRI Standards Committee Policy and Procedure document.

Metric Policy
The AHRI Standards Committee (StdC) has established the policy that all AHRI standards and guidelines will use SI units, either solely or in addition to I-P units. See section 3.3 of the AHRI Standards Committee Policy and Procedure document.

Patent Policy
The AHRI Patent Policy is found in Appendix A of the AHRI Standards Committee Policy and Procedure document.

AHRI, the Air Conditioning, Heating, & Refrigeration Institute, develops performance-based standards for equipment designed and manufactured by HVACR industry participants. These standards, which are used throughout the world, stimulate innovation and are the stepping stones to improving product performance. Through the use of industry standards and voluntary participation in AHRI's certification programs, manufacturers can improve the quality of their products, and consumers can be assured manufacturers' performance claims are accurate and rated uniformly, enabling fair comparisons. AHRI provides free access to its standards and guidelines, as well as information about how they are developed and advanced globally.

The AHRI Standards Committee, a standing committee of the AHRI Board of Directors, has oversight of the AHRI standards activity.

Safety Standards

 

AHRI does not set safety standards and does not certify or guarantee the safety of any products, components or systems designed, tested, rated, installed or operated in accordance with AHRI standards and guidelines. AHRI strongly recommends that products be designed, constructed, assembled, installed and operated in accordance with nationally recognized safety standards and code requirements appropriate for products covered by AHRI standards and guidelines. AHRI uses its best efforts to develop standards and guidelines employing state-of-the-art and accepted industry practices. AHRI does not certify or guarantee that any tests conducted under its standards or guidelines will be non-hazardous or free from risk.

 

Relationship to AHRI Certification Program

 

AHRI has established and continuously maintains certification programs to promote the use of and compliance with AHRI and other nationally or internationally recognized Standards, in support of its responsibility for leadership in the air-conditioning, heating, water heating, and refrigeration industry. The AHRI certification programs are accredited to ISO 17065 and are open to all manufacturers on an equal basis. More information about the AHRI certification program may be found http://ahrinet.org/Certification.
