This standard establishes health effects requirements for products, components and materials used in drinking water systems.

“Customers that fabricate products for drinking water use can be assured that this resin conforms to the health effects requirements for NSF 61,” says Fletcher Lindberg, AOC Business Manager for Open Mold, Reinforced Resins.

“This makes it faster and easier for those companies to obtain NSF certification for their products.”

Vipel F010-H2O is used as a coating system in tanks that hold at least 4000 gallons (15 142 litres) and piping at least 6 inches (152 mm) in diameter. When the resin is formulated and processed according to specifications, the coating system is suitable for both potable water (as demonstrated by the NSF certification), as well as sodium hypochlorite containment used in potable water systems.

Benefits of cobalt-free

Vipel F010-H2O resin uses a special catalyst that does not require a cobalt promoter. This feature makes the coating suitable for sodium hypochlorite containment. In contrast, composite materials that use cobalt-based promotion weaken over time when exposed to bleach or sodium hypochlorite, reports AOC.

“Since F010-H2O is formulated for sodium hypochlorite resistance, the composite equipment lasts longer and saves customers the cost of replacement,” explains Scott Lane, AOC Corrosion Product Leader.

About NSF International
NSF International is an independent organisation that writes standards, tests and certifies products for the food, water and consumer goods industries to minimise adverse health effects and protect the environment.

NSF's Water Programs require extensive product testing and unannounced audits of production facilities to verify that water treatment products meet the design, material and performance requirements. NSF International is accredited by the American National Standards Institute (ANSI).

NSF led the development of the American National Standards for all chemicals used to treat drinking water and materials/products coming into contact with drinking water. In 1990, the US EPA replaced its own drinking water product advisory programme with these NSF standards.

“This is a tremendous benefit for customers in the municipal water treatment sector where the use of sodium hypochlorite as a sanitiser is increasing.”
