NSF Approved Plastic Materials NSF (National Sanitation Foundation) sets standards for all direct and indirect drinking water additives. Manufacturers who provide equipment displaying the NSF symbol have applied to the NSF for device approval to a specific standard. The approval is issued for the finished product (device) in a specific use (application). To obtain device approval, all components within the device must comply with the Standard. Establishing compliance of the equipment┬ĺs components can be accomplished in one of two ways:
The component has been tested to the Standard by the component supplier and is certified as such.
,li>The equipment manufacturer must supply documentation that the component meets the Standard, If any testing is required, it must be completed by the equipment manufacturer.
The NSF maintains numerous standards. Three standards which we frequently encounter and to which some of our products have been tested are:
51 Plastics in Food Equipment
61 Drinking Water System Components┬ľHealth Effects
14 Manufacture of Fittings and for Accessories other than Pipe Fittings
