Certification
Prior to use, all clean benches should be certified by a qualified certifier. Under normal
operating conditions, the clean bench should be recertified at least annually and when
moved or serviced. The certifier should perform the following tests, as recommended in
Institute of Environmental Sciences and Technology IEST RP-CC002.4 and the
Controlled Environment Testing Association CAG-003 and CAG-014.
•
Airflow Velocity Test
•
HEPA Filter Leak Test
•
Backstreaming/Induction Leak Test
•
Work Area Air Cleanliness Test (when appropriate)
•
Light Intensity Test (when appropriate)
In addition, the following tests should also be performed at the user's discretion:
•
Electrical Leakage and Ground Circuit Resistance Test
•
Airflow Visualization Study to determine airflow patterns
If you have any questions regarding certification agencies or need assistance in locating
one, contact Labconco's Product Service Department at 1-800-522-7658 or 816-333-
8811.
Certifier Password
Never enter the password-protected area of the clean bench if you are not a trained and
qualified certifier or technician. Changing parameters in the password-protected area may
impair the product's performance and result in loss of protection.
The certifier password is: 1 9 2 5
Use this password for all normal calibration and certification activities.
Airflow Velocity Test
Velocity Profile shall establish laminar airflow of the clean bench.
The following tools are required:
•
Tape measure
•
Felt-tipped marker and tape (to mark test points on work surface)
•
Thermal Anemometer and stand (stand height must place probe at a minimum of
3" and maximum of 27")
•
Calculator
1. The blower(s) must be operating at a stable level for the airflow velocity test.
