General Performance, Component, and Other Requirements
Fans shall have certified performance ratings as evidenced by conformance
to the requirements of AMCA 211, and shall be listed in AMCA Licensed
Products, or shall be currently eligible for such listing. Fans shall
generally be in accordance with AMCA 99 unless superseded by other
requirements stated elsewhere herein. Determine performance data for fans
in accordance with AMCA 210. Select fans to minimize the exposure of
personnel working in or occupying the immediate installation area. The
total sound power level of the fan tests shall not exceed 90 dBA when
tested per AMCA 300 and rated per AMCA 301, or it shall be provided with an
appropriate attenuation device or devices. Scheduled fan performance is
the performance required under specified or indicated installation
conditions with specified or indicated accessories. The net installed air
performance of the fan, with accessories/appurtenances in place, shall be
sufficient to meet the scheduled performance within the limits of the fan
rating certification tolerance. Affix the manufacturer's product
identification nameplate to each unit. Apply additional requirements for
specific service or generic type or class of fan. If nonuniform air flow
conditions are likely to be encountered, contact the fan manufacturer to
ensure that the fan is rated for the additional fan inlet and outlet
effect. Install fans to minimize fan system effect in accordance with AMCA
201. Fans shall be listed in the Directory of Products licensed to use
