4.2 Test Environment

Normal testing will take place in the high bay of the 306E Laboratory in the 300 Area under ambient temperature and humidity conditions. portion of the test will require the addition of moisture into the airstream to increase the relative humidity to 50 to 90 (percent.

4.3 Equipment and Facilities

A full-scale mockup of the ductwork in a typic.al ventiiation pit will be required for this testing.

The building utilities required will be 240 VAC power for the air supply system, 120 VAC power for the instrumentation, compressed air, and a water source.

The instruments required for testing are listed below. An equivalent instrument approved by the Test Director may be used if the specified instrument is not available.

Laminar Flow Element, Meriam Instrument Model 50MC2-4, nominal 400 scfm air f l o w at 8" wc and 70 degrees F and 29.92" Hg abs.
