NSF/ANSI 61 Certification
The first and only company with a complete chemical tank certified to NSF/ANSI 61!
NSF/ANSI 61 addresses crucial aspects of drinking water system components.
Most products that come in contact with potable water are tested under NSF-61 with the pH 5, pH 8 and pH 10 exposure waters defined in the standard. These exposure waters were designed to simulate the wide variety of potable water chemistries encountered across North America. However, these exposure waters were not designed to predict leaching of materials caused by aggressive chemicals. To address this concern, NSF created a more extensive standard and certification. As a leader in the chemical storage tank industry, Poly Processing holds this more stringent chemical certification and to make sure we provide the safest tank systems for drinking water safety, we certified the complete system from tank to bolt washers to this strict standard.
Our NSF/ANSI 61 Certifications
Poly Processing holds three NSF/ANSI 61 certifications. We have obtained these three separate designations to bring the most value to each application while maintaining the highest standards when storing or treating potable water.
OR-1000™ resin and all associated fittings have been tested and certified by NSF for the storage of sodium hypochlorite and sulfuric acid to ensure they are safe in the treatment of potable water.
PolyCL resin and all associated fittings have been tested and certified by NSF for all the chemicals listed below excluding potable water, sodium hypochlorite,
and sulfuric acid to ensure they are safe in the treatment of potable water.
Standard HDPE tanks hold the basic NSF/ANSI 61 certification for potable water only.
