NSF 61 Barrier Materials: Potable Water 101 for Paints, Liners, Coatings, and Tanks

This presentation will be a general overview of Barrier Material type products (Paints, Liners, Coatings, and Tanks) with potable (drinking water) applications. The focus will be on NSF 61, but also cover NSF 372, NSF P151, and other applicable standards. Barrier materials are materials used to contain or form a barrier between water and another surface. Barrier Materials are used to form drinking water holding tanks or to line water reservoirs. Other distribution products such as pipes, fittings, and valves use paints and coatings as barrier materials as well. Please join us to learn about potable water barrier materials and how they are evaluated.


  • The audience will gain an understanding of what potable water standards apply in the US and Canada
  • What the different types of barrier material products are and how they may be handled differently
  • How barrier materials are tested and evaluated
  • How to interpret a listed product’s ratings
