American National Standard for Laboratory Ventilation ANSI/AIHA Z9.5-2003
6.5.1 Single Hood CAV Systems
Commissioning tests on single hood, constant air volume (CAV) systems shall consist
of:
• Fan Performance Tests;
• Exhaust Duct Measurements;
• Hood Performance Tests; and
• Hood Monitor Calibration
Fan Performance Tests shall include measurement of fan speed, fan static pressure,
motor speed, and amp draw. Exhaust duct measurement shall consist of exhaust flow
measurement and hood static pressure measurement.
6.5.1 Multiple Hood CAV Systems
Commissioning of multiple hood, constant air volume systems shall include:
• Fan Performance Tests;
• Verification of proper test, adjustment, and balance of branch exhaust flow and
static pressures (exhaust flow and static pressure for each branch duct shall be
recorded after final balancing is complete);
• Hood Performance Tests as described above in Sections 6.3.1 through 6.3.6; (See
Fume Hoods: Periodic Testing) and
• Hood and System Monitor Calibration.
6.5.4.1 CAV Laboratory Room Tests
These tests shall ensure that the ventilation system design airflow is being maintained
within the allowable tolerance in:
• All hood exhausts;
• All other bench-top and equipment exhaust provisions that may be present;
• The room general exhaust if present;
• The room supply; and
• Room air cross currents at the hood face opening.
If a specific room differential pressure (dP) has been specified, the dP shall be
measured to ensure that it is within its allowable range.
If a room differential airflow is specified, actual room differential airflow shall be
determined to ensure that it is within allowable maximum and minimum limits and in
the proper direction.
If the room has more than one ventilation control mode (that is occupied/unoccupied,
etc.), each individual mode shall be enabled and applicable parameters (that is, room
supply, room total exhaust, etc.) shall be performed for each separate mode.
Room ambient conditions (temperature, humidity, air currents, etc.) shall also be
measured to ensure they are being maintained under the conditions specified.
Also see Appendix 4 - Audit Form in
ANSI/AIHA Z9.5-2003, which provides a
comprehensive checklist for the Laboratory
Ventilation Management Program including
Commissioning Tests.
