2. Take the downflow velocity reading at each test point location of the test grid.
3. Average all individual test point velocity readings.
4. If the average is not within the acceptance criteria range, adjust the biosafety
cabinet according to
Adjusting the Blower Speed
and/or
Adjusting the Internal
Damper
found in
Section 9: Calibration
.
Acceptance Criteria
Average downflow shall be as specified in Table 10-6
column “Downflow Average” +/-5
FPM (+/-0.03 m/s), and all individual test points /-16 FPM (+/-0.081 m/s) from
the average.
