Standard Scope

AHRI Standard 1330 establishes definitions, test requirements, rating requirements, nomenclature, minimum data requirements for published ratings, marking and nameplate data, and conformance conditions for infrared heaters.


This standard applies to infrared heaters that are gas-fired high-intensity infrared heaters, gas-fired low-intensity infrared heaters, and gas-fired multi-burner continuous low intensity radiant tube heaters with inputs up to and including 117.5 kW per burner intended for installation and heating of outdoor or indoor spaces.


This standard does not apply to heaters that do not radiate their energy into a single measuring plane.
