If you manufacture, sell or distribute water treatment chemicals in North America, your products are required to comply with NSF/ANSI/CAN 60: Drinking Water Treatment Chemicals – Health Effects by most governmental agencies that regulate drinking water supplies. Developed by a team of scientists, industry experts and key industry stakeholders, NSF/ANSI/CAN 60 sets health effects criteria for many water treatment chemicals including:

  • Corrosion and scale inhibitors
  • Coagulants and flocculants
  • Disinfection and oxidation chemicals
  • pH adjustment, softening, precipitation and sequestering chemicals
  • Well drilling aids
  • All other specialty chemicals used in drinking water treatment

Benefits of Certification

Certification to NSF/ANSI/CAN 60 ensures that your product meets the regulatory requirements for the USA, Canada, Israel, Saudi Arabia, Spain and the UAE. NSF/ANSI 60 certification can often meet or fulfill the testing requirements for many other countries as well. Market leaders strive to attain NSF certification as a mark of distinction that provides their customers with assurance that the product is safe for use in drinking water.

NSF/ANSI/CAN 60 testing can also provide validation for water well products and subsurface ground fill materials to U.S. EPA drinking water requirements, as well as testing chemicals used in the hydraulic fracturing process.

Certification also allows your company to:

  • List your product in our online directory of certified drinking water treatment chemicals
  • Use the NSF certification mark on your products and in your promotional materials

  • Open Where can I find NSF listed products?

    NSF certified products can be found in our online listings.

  • Open What ensures the product consistently meets these requirements?

    For products listed for potable water applications, NSF performs at least two unannounced audits of each production facility annually. During the audit, we verify the quality control tests being done by the manufacturer and that there are no modifications to the product formulation and processing. In addition, we collect samples for laboratory retesting of each product family on an annual basis.

  • Open Whom can I contact for questions?

    If you have questions about the testing and certification of any NSF certified product, contact our Consumer Affairs Hotline at 800.673.8010 or our Regulatory Affairs Hotline at 877.867.3435, or email info@nsf.org.

  • Open Who is NSF?

    Founded in 1944, NSF International is committed to protecting and improving human health and the environment on a global scale. NSF International is a global independent organization that provides standards development, product certification, testing, auditing, education and risk management for public health and the environment. Manufacturers, regulators and consumers alike look to NSF International for the development of public health standards and certification that help protect the world’s food, water, health and consumer products.

    In 1990, the U.S. EPA replaced its own drinking water product advisory program with NSF standards, including NSF/ANSI 61, for all materials and products that treat or come in contact with drinking water. Today, most plumbing codes require certification to NSF standards for pipes and plumbing components in commercial and residential buildings.
