Section 4 - Certification Testing Procedures
A list of certification companies is included on the Thermo
Electron website, or call the Technical Services department. See
Page iii.
Service and certification must be performed by
qualified personnel.
4.1 Certification of the Cabinet
Certification is recommended:
• Annually
• If the cabinet is moved
• After replacing the HEPA filter(s)
• After service work has been performed inside cabinet
a. On-Site Certification
Due to the stress of shipping and handling and the fragile
nature of the HEPA filters, the cabinet must be thoroughly tested
when it has been placed in its final location. The following tests
should be performed:
• HEPA Filter Leak Test (DOP Test)
• Downflow Velocity Profile Test
• Face Velocity Air Flow Test
• Voltage Test
These tests must be performed by qualified service special-
ists who are familiar with the methods and procedures of certify-
ing biological safety cabinets.
The certification should be performed upon installation,
annually thereafter, after filter changes, and after cabinet reloca-
tion.
Note: Unless this certification was expressly called for in the
specification, quotes and/or purchase order, the cost for this on-
site testing is to be paid for by the customer.
