NSF is known for its work protecting public health and safety in the aquatics and recreational water industries. NSF has been evaluating, testing, auditing, certifying and writing standards for pool and spa products since 1960.

In fact, it was the pool and spa industry trade association and public health official groups that asked NSF to write standards and conduct product testing and certification of pool and spa products in 1959. This work culminated in NSF/ANSI Standard 50, which is still used today by NSF to certify chemicals, materials, and products for pool and spa use. NSF has earned the trust of stakeholders and occupies a unique position in the industry.

You may not know that NSF International also develops public health and performance standards and certifications for food, water, health and consumer products.

For example, did you know that NSF tests nutritional supplements for banned substances and evaluates label claims to meet the needs of professional athletic associations such as MLB and others? NSF can detect contaminants (such as pharmaceuticals) in concentrations as low as one part per trillion.

NSF also tests toys for child safety. NSF uses an array of advanced equipment to analyze materials and toys for banned substances and excessive quantities of chemicals such as cadmium, lead, phthalates, and other dangerous elements and compounds. NSF tests and certifies other consumer products and appliances used in and around the home including dishwashers, washing machines, dryers, and cookware.

NSF helps ensure that water and food products do not contain unsafe levels of contaminants. NSF developed the first American national standard for foodservice equipment in 1952, and currently certifies more the 360,000 products including bottled water, home and consumer products, foodservice equipment, nutritional supplements, and seafood as well as organic and gluten-free products.

NSF led the development of the American national standards for all materials and products that treat or come in contact with drinking water, and certifies products such as plumbing components, water treatment chemicals and drinking water filters. Most plumbing codes require certification to NSF standards for pipes and plumbing components in commercial and residential buildings.

NSF audits and tests bottled water and packaged ice, conducting inspections of bottling locations to sample source waters and final treated and packaged water prior to testing. NSF tests for chemical and microbiological contaminants, including those that may come from the packaging or the bottle.

NSF’s Health Sciences Division helps manufacturers meet regulations through reference standards, certification, training, consulting, GMP and GLP testing, R&D and auditing for the pharmaceutical, dietary supplement and medical device industries.

NSF Sustainability offers standards development and certification for green products including pool and spa products, carpet, flooring, fabrics and other building materials; and process verification services such as greenhouse gas verification, environmental footprinting and environmental management systems registrations.

NSF International Strategic Registrations (NSF-ISR) offers comprehensive management systems registrations to internationally accepted standards for quality assurance for the manufacturing, automotive, aerospace and medical industries (e.g. ISO 9001, ISO 14001, AS9100, etc). Accreditations attest to NSF’s competency and impartiality of services and compliance with established national and international standards for third-party certification.

NSF has over 50 internationally recognized accreditations, including ANSI, IAS, OSHA, SCC, ISO 17020 inspection agency accreditation, ISO 14001 environmental certification, ISO Guide 65 product certification accreditation, and ISO and FSSC 22000 food safety accreditation.
