CPVC Schedule 80 Pipe Certified for NSF/ANSI 14 & 61

GF Piping Systems' CPVC Schedule 80 Pipe is now certified by the National Sanitation Foundation (NSF) in compliance with NSF/ANSI Standard 14 and Standard 61. The certification assures users of suitability and safety for use in potable water applications (NSF- 14) and drinking water system components (NSF-61). The CPVC (Chlorinated Polyvinyl Chloride) Schedule 80 Pipe is designed to prevent rust, scale and pitting. The piping system can handle temperatures up to 210 F, is available in sizes from half-inch to 12 inches, and conforms to ASTM F441, F437 and F439, and ASTM D1784 Cell Classification 24448. As part of the NSF Certification process, GF Piping Systems' CPVC 80 Pipe was verified to comply with the Plastic Pipe Institute's (PPI) Technical Report Number 3 for long Term Hydrostatic Strength (LTHS). NSF/ANI Standard 14 requires materials for pressure pipe applications meet a minimum 50-year long-term strength requirement established through PPI's hydrostatic design stress. This includes testing pipes from at least three different slots of material and at 73 F and an elevated temperature typically 180 F or higher. To establish the hydrostatic design basis, products are repeatedly tested to failure to develop a stress time relationship.
