velocity for each branch [submain] and main duct in the exhaust air system.
Indicate if the test value is adequate or inadequate. Adequate hood volume
flow rates and duct velocities are those with [measured] [converted] values
within plus or minus 10 percent of design values. Adequate total system
volume flow rates are those with [measured] [converted] values within plus
or minus 10 percent of the design values.
1.4.5.6
Pitot Traverse Report
Use the "Pitot Traverse Data" sample form or comparable form to record
pitot traverse readings. Submit the following data, as a minimum, for each
test location:
a.
Velocity pressure and their corresponding velocities;
b.
c.
Duct dimensions and area;
d.
Total measured volume flow rate; and
e.
Static pressure reading.

Deadline
**************************************************************************
NOTE: Estimate the amount of time necessary for the
Contractor to make corrections and for the test
engineer to retest the system in the event that the
system fails to pass the initial test.
**************************************************************************
Provide a simplified pass/fail report within [3] [_____] days after
completion of testing. Provide a complete test report [15] [30] [_____]
days after completion of testing. [The only exception is for the last
seasonal work session which shall be completed by [_____].]
