Drinking Water Systems Standards and Protocols
- Why Work With NSF?
NSF led the development of American National Standards for all materials and products that treat or come in contact with drinking water, such as plumbing components, water treatment chemicals and drinking water filters, as well as pool and spa equipment to help protect public health and minimize adverse health effects.
Standards and protocols can provide credibility and industry acceptance for new products or emerging technologies. To find out more about developing standards or protocols, call +1 734.913.5774 or email firstname.lastname@example.org.

NSF/ANSI 60: Water Treatment Chemicals
NSF/ANSI 60 covers corrosion and scale control chemicals; pH adjustment, softening, precipitation and sequestering chemicals; coagulation and flocculation chemicals; well-drilling products; disinfection and oxidation chemicals; and miscellaneous and specialty chemicals for the treatment of drinking water. The standard addresses the health effects implications of treatment chemicals and related impurities. Learn more about NSF/ANSI 60.
NSF/ANSI 61: Drinking Water System Components
NSF/ANSI 61 sets health effects criteria for many water system products, components and materials. NSF/ANSI 61 addresses crucial aspects of drinking water system components such as whether contaminants that leach or migrate from the product/material into the drinking water are above acceptable levels in finished waters. Learn more about NSF/ANSI 61.
Residential Drinking Water Treatment Standards
NSF developed its first drinking water treatment standard in 1973. Today, we test to eight point-of-use/point-of-entry (POU/POE) drinking water treatment standards and have certified thousands of systems and components. Learn more about NSF drinking water treatment system standards.
NSF/ANSI 372: Drinking Water System Components
NSF/ANSI 372: Drinking Water System Components — Lead Content verifies the lead content of drinking water products meets levels determined by the Safe Drinking Water Act. Products certified to NSF/ANSI 372 demonstrate compliance with lead content requirements only, while products certified to NSF/ANSI 61 Annex G demonstrate compliance with both lead content and lead leaching requirements.
Why Work With NSF?NSF’s water industry experience and background can help your organization with certification to existing standards or in developing new ones. NSF is accredited by the American National Standards Institute (ANSI) to develop American National Standards. ANSI's accreditation verifies that NSF develops standards in a manner that ensures openness and due process allowing for equity and fair play.
