NSFS 347 2021 refers to the , a North American standard titled “Safety and Performance Requirements for Nonmetallic Gaskets for Use in Water and Wastewater Systems.” * Developed by NSF International (formerly the National Sanitation Foundation), this standard specifically governs nonmetallic gaskets used in piping, fittings, valves, and other appurtenances that come into contact with:

Next time you see a “compostable” fork, ask: Is it NSF 347 certified? If not, the claim might be just hot air.
The standard applies to all major single-ply commercial roofing formulations: (Thermoplastic Polyolefin) PVC (Polyvinyl Chloride) EPDM (Ethylene Propylene Diene Terpolymer) KEE (Ketone Ethylene Ester) PIB (Polyisobutylene) The Five Pillars of Evaluation nsfs 347 2021

By evaluating the entire product life cycle, the standard prevents "greenwashing" and ensures that an improvement in one environmental area does not inadvertently cause a negative impact elsewhere. 2. The Five Core Pillars of Evaluation
Another significant aspect of NSF's work is its support for research and innovation. Through funding grants for research projects, the NSF enables scientists and engineers to explore new ideas, conduct experiments, and develop technologies that can lead to breakthroughs in various fields. This support not only contributes to the body of knowledge in specific areas but also has the potential to lead to practical applications that improve people's lives and drive economic growth.

Whether you are a water utility engineer, a gasket manufacturer, or a plant maintenance manager, understanding NSFS 347 2021 is not optional—it is a legal and safety necessity. The 2021 revision closes loopholes on aging, chemical leachates, and mechanical durability that led to real-world failures in earlier editions. Noncompliant gaskets risk water contamination, system leaks, and regulatory penalties. Always specify, purchase, and install only gaskets bearing valid NSFS 347 2021 certification.
Using NSF/ANSI 347-certified products helps projects gain credits for green building rating systems, such as LEED, due to the standard's rigorous, comprehensive approach. Better Performance and Longevity
