AWWA C900 / AWWA C905

Fusible C-900® and Fusible C-905® pipe is manufactured and tested in accordance with the requirements of AWWA C900 and C905, respectively. AWWA C900 and C905 compliance is verified by:

  1. Certificates of compliance from the pipe manufacturer; and
  2. NSF 61 certification to the AWWA C900 and C905 Standards from NSF International, The Public Health and Safety Company™, which provides public health and safety risk management solutions to companies, governments and consumers around the world.

Additionally, specimens from each Fusible C-900® and Fusible C-905® pipe lot undergo further testing by a third-party, independent national testing laboratory to verify pipe quality.

Manufacturer and third-party certification of compliance with AWWA standards is consistent with pipe industry practice. AWWA does not "test, certify, or approve any product." Nor does AWWA provide interpretation of its own standards. AWWA creates and maintains industry standards, and industry users are responsible to interpret and confirm compliance with those AWWA standards.

Both bells and gaskets are addressed in the AWWA C900 and AWWA C905 pipe product standards. This is appropriate because the bells are formed and the gaskets are installed as part of the pipe manufacturing process. Butt fusion, however, is a field joining method. Field joining methods are not included in product manufacturing standards, such as AWWA C900 and AWWA C905, because they are outside of the pipe manufacturer's control. This treatment is consistent with other common PVC joint restraint options (Megalug®, CertaLok™, Terra-Brute®, Eagle Lok 900™, and Diamond Lok-21®), none of which are cited in AWWA C900 or C905. AWWA C900 and AWWA C905 do not cover field joining methods.

AWWA C605 is the installation standard for AWWA C900 and C905 PVC pipe. A revised version of AWWA C605 was recently released for public comment following approval by both the AWWA Standards Committee on Polyvinyl Chloride Pressure Pipe and Fittings and the AWWA Standards Council. The revised version includes thermal butt fusion of PVC as a joining technique. It is important to note, however, that the absence of a thermal butt fused joint from earlier versions of C605 does not preclude the use of butt fusion with PVC pipe as made clear in the foreword to AWWA C605-05: "The standard is not intended to preclude the manufacture, marketing, purchase, or use of any product, process, or procedure."

In summary, independent third-parties verify that Fusible C-900® and Fusible C-905® pipe is manufactured and tested in accordance with the requirements in AWWA C900 and AWWA C905.

Fusible PVC® is the most tested PVC Pipe in the Industry with four levels of quality control to help ensure flawless installations.

UGSI's Quality Assurance/Quality Control chart

Fusible C-900® and Fusible C-905® pipe undergoes three levels of quality control to help ensure compliance with AWWA C900 and AWWA C905. In addition, UGSI requires QC data-logging of all field fused joints.
