Certification to NSF/ANSI 61

Protective coating systems used in North America for potable water application are required to comply with NSF/ANSI 61: Drinking Water System Components – Health Effects by most governmental agencies that regulate drinking water supplies.

Certification to NSF/ANSI 61 ensures that the coating product meets the regulatory requirements for the U.S. and Canada, and it can often meet or fulfill the testing requirements for many other countries as well. NSF/ANSI 61 testing covers all products with drinking water contact from source to tap, and determines what contaminants may migrate or leach from your product into drinking water. It also confirms if they are below the maximum levels allowed to be considered safe. The NSF certification as a mark of distinction provides the customers with assurance that the certified product is safe for use in drinking water.

For potable water pipeline application, American Water Works Association (AWWA) Standard AWWA C210 Liquid-Epoxy Coating Systems for the Interior and Exterior of Steel Water Pipelines sets minimum requirements for shop- and field-applied, liquid-epoxy interior linings and exterior coatings used in the water-supply industry for steel water pipelines installed underground or underwater, under normal construction conditions. AWWA Standard C222 Polyurethane Coatings for the Interior and Exterior of Steel Water Pipe and Fittings sets minimum requirements for shop- and field-applied polyurethane interior linings and exterior coatings used in the potable water supply industry.

Strathmore’s Coating Subject Matter Experts are the leaders in developing potable water coatings. As a matter of the fact, the very first edition of the AWWA Standard C222 standard was drafted by one of our Strathmore’s Coating Subject Matter Experts. We have abundant experience in designing, formulating, applying, and inspecting coatings and linings used for potable water application.  Strathmore offers Strathane PW - a 100% solids, 1:1, high performance potable water grade polyurethane coating as per AWWA C222.
