3.2.3
Preliminary Tests
Conduct an operational test on the entire exhaust duct systems, components,
and equipment for a period of not less than 6 hours after power
transmission components are adjusted. Replace filters, if any, after
preliminary tests and prior to conducting final acceptance tests.
3.2.4
Testing, Adjusting, and Balancing Work
Perform work in accordance with the applicable and recommended procedures
of: ACGIH-2092S. Provide apparatus, certified, calibrated,
power factor. Unless approved otherwise, instruments shall be limited to
manometers and approved aneroid type gages (such as a Magnehelic).
Velometers may be used for low velocity measurements if approved by the
Contracting Officer.
3.2.5
Systems Volume Acceptance Criteria
Systems final volume shall be within the following limits:
Fan:
Plus 10 percent, minus zero percent of design volume at design
temperature
Hood or Equipment: Plus or minus [5] [10] percent of design volume at
design temperature
Note: Tolerances shall be taken on clean or dirty conditions as indicated
on the drawings.
3.2.6
Sound Level Tests
Report to the Contracting Officer in writing, sound levels higher than 84
addition to being included in the required test reports.
3.3
SYSTEM[S] OPERATION DEMONSTRATION
After systems and equipment testing, adjusting, and balancing has been
completed and accepted, demonstrate the complete and correct functioning of
systems equipment and controls by operation through normal ranges and
sequences, and by simulation of abnormal conditions, [including the manual
tripping of fire dampers]. Manually and automatically cause every device
to function as intended. Readjust, as necessary, any settings and after
sufficient operating time, but not less than [6] [_____] hours, verify
ability of equipment and controls to establish and maintain stable and
accurate operation and required system performance. Note any abnormal
deviations, such as excessive vibration, noise, and heat, binding damper
mechanisms, and incorrect fan rotation. Make any necessary repairs,
replacements or adjustments.

SCHEDULE
Some metric measurements in this section are based on mathematical
conversion of inch-pound measurements, and not on metric measurements
commonly agreed on by the manufacturers or other parties. The inch-pound
and metric measurements shown are as follows:
