5.4 Certification Testing Methods and Equipment
After installation and prior to use, NuAire recommends that the cabinet be certified or commissioned to factory standards.
As a part of certification, the certifier should go through the following initial checklist to assure all aspects of the LFBSC
installation are complete and ready for certification.

Review product installation

Exhaust connection

Damper valve installed correctly with label toward front

LFBSC base stand level

Verify airflow sensor shroud is in place

Downflow

Verify configuration type selection for specific model * (see section 7.5.2)

Verify setpoints and alarm limits for specific model * (see section 7.5.2)
 Perform BCS certification

At a minimum, the following tests should be performed:

HEPA filter leak test

Downflow velocity test

Inflow velocity test

Airflow smoke patterns

Site installation assessment tests

Perform Site Assessment Tests

The NU ‐ 430 requires verification of the supply fan interlock and back ‐ up pressure switch operation utilizing
independent exhaust volume measurement instrument (DIM). Per NSF/ANSI 49, a 20% loss of exhaust
volume must produce an airflow alarm within 15 seconds.
The testing methods and equipment required are specified on the factory inspection report included with this manual.
(See insert in back cover)
NOTE: IT IS RECOMMENDED THAT THESE TESTS BE PERFORMED BY A QUALIFIED TECHNICIAN WHO IS
FAMILIAR WITH THE METHODS AND PROCEDURES FOR CERTIFYING BIOLOGICAL SAFETY CABINETS
(SEE INSERT)
NOTE: AFTER THE INITIAL CERTIFICATION, NUAIRE RECOMMENDS THAT THE CABINET BE RECERTIFIED (AT A
MINIMUM) ON AN ANNUAL BASIS AND AFTER EVERY FILTER CHANGE OR MAINTENANCE ACTION OR
ANY TIME THE OPERATOR FEELS IT IS NECESSARY.
Note that the LABGARD ES cabinets, filters, and seals provide premium performance. Quality Control in both design and
manufacturing assure superior reliability. However, protection to both product and operator is so vital that certification to
the performance requirements should be accomplished as stated to ensure biological safety established by the factory
standards.
* If the specific model is a special product with non ‐ standard setpoints and alarm limits, the new values will
be located on the factory Inspection Report.
