Proposed Standards and Guidelines

AHRI standards and guidelines are used throughout the world. They stimulate innovation and creation and are the stepping stones to improving product performance. Through the use of industry standards and voluntary participation in AHRI's certification programs, consumers can be assured manufacturers' performance claims are accurate and rated uniformly, enabling fair comparisons. AHRI provides access to its standards and guidelines, as well as information about how they are developed and advanced globally.
