The AMCA Laboratory
Encompassing more than 25,000 sq ft (2,323 sq m) of the
AMCA International headquarters building in Arlington
Heights, the AMCA International laboratory is the standard
to which all AMCA-accredited independent laboratories
(Figure 2) are held. All instrumentation within the facility
is continually calibrated and checked against the instrumentation
in dozens of laboratories around the world.
In addition to being A2LA-accredited, the AMCA
International laboratory is U.S. Environmental Protection
Agency- (EPA-) approved to test and certify products for the
EPA's Energy Star program. It is equipped to test a variety
of fan types, as well as louvers, dampers, energy-recovery
ventilators, air curtains, evaporative coolers, power roof
ventilators, positive-pressure ventilators, single-room
air handlers, and airfl ow-measuring stations for various
kinds of effi ciency, leakage, and stability beyond air and
sound performance.
The AMCA International laboratory includes:
■
Four reverberation rooms ranging in size from 6,300 cu
ft (178 m3) to 65,500 cu ft (1,855 m3), where inlet, outlet,
and total sound power are measured.
■
Two water-test chambers in which up to 8-in.- (20 cm)
per-hour rainfall and 50-mph (22.4 m/s) wind can be

simulated for tests of the water-rejection capabilities of
louvers.
■
Three multinozzle chambers capable of measuring up
to 88,000-cfm (41.53 m3/s) airfl ow.
■
A thrust-measurement rig able to accommodate circulating
fan heads up to 72 in. (183 cm) in diameter.
■
Adjacent reverberant rooms used for testing acoustical
louvers in accordance with ASTM E90, Standard Test
Method for Laboratory Measurement of Airborne Sound
Transmission Loss of Building Partitions and Elements.
A rig for testing ceiling fans up to 18 ft (5.5 m) in diameter.
Larger fans up to 24 ft (7.3 m) in diameter are
tested off site.
■
A rig for testing jet fans up to 55 in. (140 cm) in diameter.
Beyond the CRP, AMCA performs contract testing
for external parties. By mutual agreement with a client,
AMCA can modify and adapt procedures to test many
air-movement-and-control devices that are outside the
scope of the CRP.
