  • Certification Process

NSF International tests and certifies Class II (laminar flow) biosafety cabinetry, which is designed to minimize the hazards inherent in working with biosafety agents of levels 1, 2, 3 or 4.

We test to NSF/ANSI 49, which includes basic requirements for design, construction and performance to provide personnel, product and environmental protection; reliable operation; durability; cleanability; noise level and illumination control; vibration control; and electrical safety.

In addition, the standard includes detailed test procedures and informational annexes, including recommendations for installation, field certification tests and decontamination procedures.

Benefits of Certification

NSF is the only third-party organization with over 40 years of commitment and service to the biosafety cabinet community. The NSF mark demonstrates that your product meets the design, construction and performance requirements of NSF/ANSI 49. In addition, we use our industry expertise to evaluate and accredit biosafety cabinet field certifiers to meet stringent requirements for experience, training and job performance.

Why Work With NSF?

NSF is recognized throughout North America as the leader in the certification of Class II biological safety cabinets. The majority of users in hospital and research laboratories demand certification to the NSF standard.

The industry, recognizing the need for demonstrated performance to ensure protection of public health, safety and the environment, pursues the NSF mark as a symbol of their commitment to producing quality, reliable products. Our certification program is accredited by the American National Standards Institute (ANSI-Accredited Product Certification Body - Accreditation #0216).

Certification Process

Upon request, we provide information describing the program, including an application form, certification requirements, timing and cost. Your returned application and deposit initiate the formal certification process.

We generally start with product testing. Once we establish conformance to the standard, including review and approval of the product literature, we schedule an initial inspection of the manufacturing facility. Following the inspection, including any necessary corrective action, we certify your product.

Following initial certification, we perform annual inspections of the manufacturing facility and partial product retesting every five years. Additional evaluations may be necessary as the policies and standard are revised.
