AHRI 1350 (I-P) and 1351 (SI): Mechanical Performance Rating of Central Station Air-handling Unit Casings (with Addendum 1)

This standard applies to the enclosure which houses the fans, coils, filters, and other components of the central station air-handling unit (CSAHU). It establishes the test requirements, rating requirements, and minimum data requirements for the casing deflection rating class, casing air leakage class, thermal transmittance class with leakage, thermal transmittance class without leakage, and thermal bridging class.
