Standards

The Standards Policy Committee has approved the details of AHRI’s new standards development process under Reinvent. Under this process, AHRI decides whether the standard ought to be an ANSI and/or an SCC standard. If ANSI and/or SCC approval for the standard is not required, then AHRI will follow a streamlined approval approach. AHRI requires ANSI and/or SCC designation for certain AHRI standards.

For example, standards covering regulated products, and those used globally or referenced in building codes may need ANSI or SCC designations. For those standards submitted to ANSI and/or SCC, AHRI procedures will incorporate balanced committees that include outside stakeholders with voting rights throughout the development of the standard. The Standards Committee appoints members to Consensus Standards Project Committees (CSPCs) to develop each of its standards.
