NSF’s accreditation program evaluates the proficiency of individuals who perform routine field certification of biosafety cabinets. The program includes written and practical, hands-on examinations, along with continuing education requirements. Applicants must also provide calibration records for their testing equipment to ensure it meets specifications.

NSF's program is recognized throughout North America and worldwide as the leader in the accreditation of individuals who perform field certifications of Class II biological safety cabinets.

Benefits of Accreditation

The NSF mark represents the only third-party organization with over 40 years of commitment and service to the biological safety community.

The majority of users in hospital and research laboratories demand accreditation of their service providers. The industry, recognizing the need for demonstrated knowledge and skills to ensure protection of public health, safety and the environment, views NSF-accredited field certifiers as providing quality, reliable field certification services.

Why Work With NSF?

NSF's services offer global recognition and exposure, with worldwide operations including all fifty states, U.S. territories and 120 other nations. We also have partnerships with peer organizations in Canada, Mexico and Europe. Thousands of companies have come to depend on NSF for demonstrated compliance to recognized standards and to provide the uncompromised integrity of global recognition and acceptance.

Accreditation Process

Upon request, we provide information describing the program, including an application form, accreditation requirements, written and practical examination outlines, an examination reference list, timing and cost. Your completed, returned application initiates the formal accreditation process.

Successful completion of both the written and practical examinations is required for accreditation. Most people start with the written exam. We coordinate the exams with you and the proctor(s).

You can take the written exam in a location near you, such as a local public library, high school, college or university, government office or other neutral setting. You provide us your desired location and the name, phone number and address of the individual who has agreed to be the proctor, and we determine the acceptability of the individual and location. We provide the examinations directly to the approved proctor who also returns all materials to us for scoring.

You have three and a half hours to complete the written examination, which has120 questions covering areas such as testing, biosafety, decontamination, cabinet design, etc. A minimum score of 80 percent is required to pass the test.

Only NSF representatives are qualified to proctor the practical examination, which can be taken at these locations:

  • Agape Instrument Services, Cincinnati, OH
  • CEPA Company, Ontario, CA
  • Eagleson Institute, Sanford, ME
  • ENV Services, Hatfield, PA
  • Micro-Clean, Inc., Bethlehem, PA

The practical exam evaluates the ability to perform all nine tests identified in Annex F (Field Tests) of NSF/ANSI 49. You must supply your own calibrated test equipment.

A 70 percent score is required for the noise level, vibration and lighting intensity tests. A 90 percent score is required for the HEPA filter leak, downflow velocity, inflow velocity, cabinet leak, airflow smoke patterns and site installation tests.

Following initial accreditation, you must supply equipment calibration documentation at the start of each calendar year. You must become re-accredited every five years, either through accumulation of sufficient requalification units or re-examination.
