The certification process begins by contacting the particular program office which handles the product type, in this case biohazard cabinetry. This initial contact can be made by telephone, fax, e-mail , or a scheduled visit to NSF's headquarters. The program office will promptly provide all of the necessary information describing the program, including application form, certification requirements, timing, and cost. The returned application and associated fee will initiate the formal process leading to certification.
Product testing is generally the first step of the process.
Once conformance to the standard is demonstrated, including review and approval of the product literature, an initial inspection is scheduled of the manufacturing facility. Following completion of the inspection, including any necessary corrective action, contracts for certification are issued. Following initial certification, inspection of the manufacturing facility is performed annually, and product retesting performed at least every seven years. Additional evaluations may be necessary as the policies and standard are revised. The NSF Mark symbolizes the only third-party organization with over 50 years of commitment and service to the industry and the regulatory community.
