NSF/ANSI Standard 14 has been in place for more than 45 years and is highly recognized by code and regulatory officials, manufacturers and plumbers to verify the performance and safety of plastics piping system components and related materials. The standard contains physical, performance and quality requirements and also requires ongoing monitoring for plastic piping system components and related materials. It addresses any material used in a plastic piping system, including PVC, CPVC, PE, PEX, ABS, NP, PP, as well as brass, copper, composites, and other materials. Additionally, the standard includes criteria for PVC ingredients.
NSF/ANSI 14 also includes requirements for dezincification (corrosion of brass) and stress corrosion cracking (cracking due to mechanical stress and exposure to a corrosive environment) of brass materials used in plastic piping systems. The standard also requires that products intended for use in drinking water applications comply with NSF/ANSI Standard 61: Drinking Water System Components – Health Effects, which includes requirements for all devices, components and materials that come in contact with drinking water.
