Testing & Certification
Our laboratory testing and certification experts are trained and equipped to ensure your lab facility maintains or exceeds regulatory compliance. Compliant labs create a workplace which is both ecologically responsible and adheres to rigorous safety standards for your employees. Our NSF International accredited examiners primarily test and certify chemical fume hoods, laminar flow hoods, biological safety cabinets, and clean rooms.
Many labs require annual certification for safety reasons. If you’re located near our Wisconsin-based headquarters, we can travel to your facility each year for testing. We service research and industrial laboratories throughout the Midwest and Great Lakes regions of the United States.
If your facility is outside of these states, certification and testing services are still available during the installation process. Contact one of our project managers for more information on how to build a safe laboratory:
PSA offers testing and certification services for laboratory containment devices, including the following:
We recommend all new hood installations be tested on-site as mandated by the ANSI/AIHA/ASSE Z9.5-2012 Standard for laboratory ventilation. In addition to new types of fume hoods, we also recommend hoods which have never been performance tested undergo benchmarking to ensure optimal performance.
PSA uses the ANSI/ASHRAE 110-1995 Test Method to evaluate chemical fume hood function. This test is recommended for originally commissioning a new hood, verifying functionality of never-tested hoods, or when major mechanical changes are made to a hood or the lab in which the hood operates. ANSI/ASHRAE 110-1995 is a quantitative test using tracer gas to measure hood containment ability in parts per million (ppm).
After testing, PSA will provide a comprehensive performance report for each fume hood. You can use this report to set a baseline whenever you need recertification.
Following the initial ANSI/ASHRAE 110-1995 evaluation, a less rigorous test can be used for required annual evaluations. This comprehensive annual inspection ensures the hood is providing the same level of protection as found during the original inspection.
To ensure proper function, biosafety cabinets must be certified at equipment installation and annually thereafter. The certification procedure as outlined by NSF International's Standard 49 ensures proper air balance and leak-free filters. PSA holds an NSF Accreditation for Class II Biosafety Cabinet Field Certification (certificate number C0106671-02).
Many labs use laminar flow to remove contaminated air from the room. Laminar flow benches, also known as Unidirectional Flow Clean Air Devices, are to be certified at installation and annually thereafter. PSA follows IEST-RP-CC002.3 and ISO14644-7 as the recognized standards.
This certification ensures the laminar flow devices are operating at the correct airflow and the filters are sealed to provide particulate-free air to the work area. PSA's technicians have the latest factory-calibrated equipment and training.
Clean rooms are designed to be controlled areas of a lab free from contamination. Certain industries have very strict requirements for clean room certification. Everything from the air to the counters must be carefully monitored for cleanliness.
Like all laboratory safety equipment, clean rooms must be commissioned at startup and validated annually thereafter. In addition to using regularly-calibrated testing equipment, PSA holds membership in the Controlled Environment Testing Association (CETA).
PSA's thorough testing includes:
We have the following types of fume hoods available:
|High Performance||Perchloric Acid||Snorkel Exhaust|
|Add Air||Walk-In||Variable Air Volume (VAV)|
|Low Bench||Demonstration||Thin Wall|
PSA consults with clients to develop customized testing and certification protocols. Tell us about your lab’s applications and certification needs and we will work with you to develop the custom testing methods you need.
Before your ventilation system can be certified, your lab has to be built. We design and install:
|ANSI/ASHRAE||American National Standards Institute/American Society of Heating, Refrigerating and Air-Conditioning Engineers|
|CETA||Comprehensive Economic and Trade Agreement|
|IEST||Institute of Environmental Sciences and Technology|
|ISO||International Organization for Standardization|
|NSF||National Science Foundation|
Safety is top priority for your lab! Contact PSA to ensure your laboratory equipment meets the standards required for personnel safety and up-to-date environmental compliance.
