White Paper: Polyethylene Gas Pipe Certification
Third-party certification of gas piping and distribution systems provides utility engineers, regulators, manufacturers and communities assurance that products are independently certified to meet specific industry standards. Testing and certification of these products can help reduce liability, increase confidence and product acceptance, and help guarantee product consistency by meeting all applicable requirements.
In many regulatory schemes, such as waterworks regulations, plumbing and mechanical codes, third-party testing and certification is a requirement for plastic piping. NSF tests and certifies PE gas piping under NSF/ANSI 14 to the following performance standards to ensure the quality and safety of gas piping and distribution systems:
- ASTM D2513: Standard Specification for Polyethylene (PE) Gas Pressure Pipe, Tubing, and Fittings
- CSA B137.4: Polyethylene (PE) Piping Systems for Gas Services.
NSF/ANSI 14 is a broad-based standard that establishes the basic requirements and for the listing of plastic piping for a variety of end uses such as gas, potable water, geothermal, drain, waste, vent, industrial, fire safety, and heating and cooling applications.
Obtaining certification to NSF/ANSI 14 requires:
- product formulation registration
- facility inspections
- materials and product testing
- quality control testing
- annual reviews.
Certification
Utilities specifying product certification by NSF can derive the benefit of an independent evaluation of product performance. These independent services come at no cost to the utility and may be the best way to ensure quality in PE gas piping products.
