AIE Lab Services and American Instrument Exchange have been working with biosafety cabinets and clean air systems from The Baker Company, Nuaire, Thermo Scientific, Labconco, Kewaunee, Air Clean, Erlab, Flow Sciences, and more for over fifty years. Our staff has decades of combined experience with repairs, refurbishments, filter changes, and decontaminations, meaning we have a wealth of knowledge with us for every project we tackle.
NSF/ANSI 49
Biosafety Cabinet Testing + Certification
All biological safety cabinets are certified to meet NSF-49 guidelines in order to verify that the cabinet provides protection to your product, person, and environment
The following are the potential tests performed as described by NSF:
Pressure Decay / Soap Bubble
Determines the overall seal integrity of the cabinet outer hull, including exterior surfaces of all plenums, welds, gaskets, plenum penetrations, and seals.
- Pressure Decay – The cabinet shall hold 2 inches w.g. (500 ± PA) ± 10% for 10 minutes.
- Soap Dubble – All weds, gaskets, penetrations, and seals on exterior surfaces of air plenums shall be free of soap bubbles when at 2 inches w.g. (500 ± PA) ± 10% pressure above atmospheric.
HEPA/ULPA Flter Lak Test
Determines the integrity of downflow and exhaust HEPA/ULPA filters, filter housings, and filter mounting frames.
Site Installation Assessment Tests
Performed to verify that the biosafety cabinet is integrated properly into the facility.
This includes:
- Sash alarms
- Exhaust airflow alarms and interlock
- Exhaust alarm systems – Type B1 or B2 hoods
- Exhaust alarm system – Type A1 or A2 canopy connection
- Exhaust alarm system – Type C1
- Cabinet alarm systems – Type A1, A2, or C1
- Airflow alarm system – Type A1, A2, or C1
- Internal supply /exhaust fan interlock alarm – Type A1, A2, or C1
Electrical Leakage and Ground Crcuit Resistance and Polarity Tests
All new cabinets shall conform the requirements of the current edition of any national standard that is based on IEC610-1. Cabinets initially qualified under versions of NSF/ANSI 49 prior to the 2009 edition shall conform to UL61010A-117 or may refer to NSF 49-1992 for Electrical Leakage, Ground Circuit Resistance, and Polarity tests if necessary.
Motor/Blower Performance
Demonstrates that when the cabinet is operated at the nominal set point velocities and without readjusting the fan speed control, a 50% increase in pressure drop across the new filter shall not decrease total air delivery more than 10%.
Downflow Velocity Test
Measures the velocity of air moving through the cabinet workspace 4 inches (100 mm) above the bottom edge of the sash.
Inflow Velocity (Face Velocity) Test
Determines the measured and calculated inflow velocity through the work access opening and the calculated exhaust flow volume rates.
Personal, Product, and Cross-Contamination Protection (Biological) Tests
Determine whether aerosols will be contained within the cabinet, outside contaminants will not enter the cabinet work area, and aerosol contamination of other equipment in the cabinet will be minimized.
Airflow Smoke Patterns Test
Determines the airflow along the entire perimeter of the work access opening is inward, that airflow within the work area is downward with no dead spots or refluxing, that ambient air does not pass on or over the work surface, and that there is no escape to the outside of the cabinet at the sides and top of the sash.
All biosafety cabinets certifications are performed with standard operating procedures which are updated regularly to comply with federal guidelines.
Due to the specialized knowledge required for a proper and safe certification of biosafety cabinets, NSF International administers an accreditation program to accredit field certifiers. Field certifiers must pass a written and practical test administered by NSF before becoming accredited. In addition, continuing education and periodic reexaminations are required for accreditation.
