Developed by a team of scientists, industry experts and key industry stakeholders, NSF/ANSI/CAN 61 sets health effects criteria for many water system components including:

  • Protective barrier materials (cements, paints, coatings)
  • Joining and sealing materials (gaskets, adhesives, lubricants)
  • Mechanical devices (water meters, valves, filters)
  • Pipes and related products (pipe, hose, fittings)
  • Plumbing devices (faucets, drinking fountains)
  • Process media (filter media, ion exchange resins)
  • Non-metallic potable water materials

U.S. and Canadian Approvals

Drinking water system components that are used in centralized water treatment plants and water distribution systems up through the water meter are typically regulated by state or provincial drinking water agencies.

Forty-eight U.S. states have legislation, regulations or policies requiring drinking water system components to comply with, or be certified to, NSF/ANSI/CAN 61.

Eleven Canadian provinces/territories require drinking water system components to comply with the requirements of NSF/ANSI/CAN 61.
