The certification process begins by contacting the program office. This initial contact can be made by telephone, fax, email, 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 of the manufacturing facility is scheduled. 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.

When people see the Mark, they know the product has met the initial and continued stringent certification requirements of NSF, the premier, independent, not-for-profit organization for public health, safety and environmental quality standards and certification.
