NSF/ANSI 61: Drinking Water System Components – Health Effects
NSF/ANSI 61: Drinking Water System Components – Health Effects is an American National Standard that establishes minimum health-effects requirements for the chemical contaminants and impurities that are indirectly imparted to drinking water from products, components and materials used in drinking water systems. This standard does not establish performance, taste and odor, or microbial growth support requirements for drinking water system products, components or materials.
NSF/ANSI 61 is intended to cover specific materials or products that come into contact with drinking water, drinking water treatment chemicals or both. The products and materials covered by the scope of this standard include but aren’t limited to:
- Protective barrier materials (cements, paints, coatings)
- Joining and sealing materials (gaskets, adhesives, lubricants)
- Mechanical devices, including treatment products (water meters, valves, filters)
- Pipes and related products (pipes, hoses, fittings)
- Plumbing devices (faucets, drinking fountains)
- Process media (filter media, ion exchange resins)
- Nonmetallic potable water materials
The standard is routinely monitored and updated by a joint committee comprised of equal parts public health experts, end users and industry members.
