NSF International has been recognized as a leader in public health safety for over 65 years. For the last 50 years, NSF has been helping people Swim Safer by meeting the needs of public health inspectors, product manufacturers, aquatic facility managers, facility users, and homeowners through a vast array of testing and certification services.
At the core of NSF's service offerings to this industry is the NSF Pool and Spa Equipment Program. This program encompasses voluntary standards, such as NSF/ANSI Standard 50, plus various standards criteria from ASTM, ASME, and others.
Of all the relevant pool and spa industry standards and criteria, NSF/ANSI Standard 50 is special due to the manner in which it was created and its continued evolution. Like all NSF-developed standards, NSF 50 represents a consensus of voting membership with a balance between manufacturers, users, and regulatory authorities. This ensures that products evaluated and certified by NSF to NSF/ANSI Standard 50 have the greatest acceptance. It's the reason product manufacturers and specifiers and, of course, public health officials, look for the NSF Mark.
NSF also offers a voluntary conformity assessment program, which includes laboratory testing, production facility audits, and certification, to verify ongoing standard compliance. The registered NSF Certification Mark on a pool, spa, or hot tub system component confirms that NSF has assessed - and certified - its conformity with the relevant section of NSF/ANSI Standard 50 and/or other product standards.
In addition, NSF conducts annual audits at each authorized production facility to assure that certified products continue to comply with the appropriate standard requirements. Audits include:
