NSF certification ensures your gas pipeline products meet the highest quality requirements and provides gas utilities, code/regulatory officials and consumers with confidence in the quality and safety of your product. NSF has a long history in the plastics industry. Our experts actively serve on committees — including the Plastics Pipe Institute (PPI) Hydrostatic Stress Board, ASTM, ASME and AGA — to promote the long-term quality and safety of plastic pipe for a variety of applications.

Benefits of Certification

NSF provides a comprehensive program to ensure the quality and safety of plastic gas distribution pipe system components. As part of our certification program, products are tested to applicable material standards such as ASTM D3350, required to meet hydrostatic design stress in accordance with the Plastic Pipe Institute (PPI) and evaluated against ISO 13477 or ISO 134780 for rapid crack propagation (RCP).

In the gas distribution industry, safety is the top priority. Our pipe testing and certification program involves rigorous testing, manufacturer facility audits and frequent retesting, yielding the highest quality products on the market.

Why Work With NSF?

NSF, the plastic industry’s leading testing and certification organization, demonstrates ongoing compliance with 49 CFR 192: Transportation of Natural and Other Gas by Pipeline: Minimum Federal Safety Standards. We also offer unparalleled third-party testing and certification to the most common gas application standards such as:

  • ASTM D2513
  • CSA B137.4
  • ASME B16.40

The NSF mark, well respected by public health officials, retailers and consumers, is recognized as a symbol of product quality and integrity. Our responsive personalized service quickly guides your products through the certification process, ensuring that they get to market on time and on budget. We offer bracketing services wherever possible to help keep costs down, and provide the pricing up front so there are no hidden surprises down the road.

NSF International has the qualifications and reputation to help your business meet the needs of the market and get the recognition and acceptance that is critical to your company’s success.

Certification Process

While our product evaluations are thorough, our process is simple and efficient. A dedicated NSF project manager serves as your single point of contact from application to approval for a streamlined, efficient certification process.

  1. Your company submits an application.
  2. Your company and suppliers provide formulation, design specifications and product end use information.
  3. We review formulation and engineering specifications.
  4. We perform a plant audit and sample collection.
  5. We conduct laboratory testing.
  6. We grant certification for compliant products.
  7. Our follow-up program includes unannounced inspections and annual testing.

Our experts can help you reduce your overall costs and expedite your time to market by bundling services and reducing the number of contracted service providers and facility audits.
