No other independent testing programs require companies to comply with the strict standards imposed by NSF and its product certification programs. From extensive product testing and material analyses to unannounced plant inspections, NSF is the only third-party testing organization to undertake a complete evaluation of every aspect of a product’s development before it can earn our certification.
Most importantly for you, NSF Certification is not a one-time activity. We do not just test a single model of a product and give it our okay. Our certification programs require regular on-site inspections of the manufacturing facilities. In addition, certified products are periodically re-tested against the requirements of the most current version of the applicable national standard. If for any reason a product fails to meet one or more of our certification criteria, we will take whatever enforcement actions we deem necessary to protect the public, including product recall, public notification, or de-certification.
Please note that NSF does not rate or compare the products we certify. We understand that each consumer has unique needs, so we developed our programs to verify that each product we certify meets the requirements of the applicable national standard. In addition, if a performance claim is being made for a product, such as a water treatment device, we ensure that the product actually is able to meet that claim.
Credibility is what NSF Certification is all about.
NSF uses the terms “certified” or “listed” in connection with a product, good, component, system, material, compound or ingredient (“Product”). A Product that is certified or listed means that NSF: (1) reviewed the Product, most often through a sampling of the Product; (2) determined at the time of the review that the Product complies with the relevant NSF consensus standard and/or protocol (“Standard”); and (3) conducted or will conduct (as more specifically set forth in the Standard) periodic audits to review whether the Product continues to comply with the Standard. After NSF certifies or lists the Product, NSF authorizes the manufacturer of the Product to use the NSF Mark on or in connection with the sale, use or distribution of that Product. The NSF Mark conveys that an independent, third-party organization (NSF) has determined that the Product complies with the relevant Standard.
