Two New Plastic Piping Standards Answer a Call for Tighter Criteria

Municipalities, specifying engineers and piping system owners are now requiring tighter criteria for piping products. ASTM International Committee F17 on Plastic Piping Systems has responded by developing two new standards that answer the call for more detailed criteria within the industry. Both of the new standards, F 2487, Practice for Infiltration and Exfiltration Acceptance Testing of Installed Corrugated High Density Polyethylene Pipelines, and F 2510/F 2510M, Specification for Resilient Connectors Between Reinforced Concrete Manhole Structures and Corrugated High Density Polyethylene Drainage Pipes, are under the jurisdiction of Subcommittee F17.20 on Joining.

John Kurdziel, F17 member and director of technical services and market development, Advanced Drainage Systems, says that Practice F 2487 will be used as a field test for installed pipe. “Most of the standards for corrugated polyethylene pipe rely on laboratory tests to certify the design performance of the joint,” notes Kurdziel. “Although laboratory testing does ensure the joint can achieve the required level of performance, there was no field correlation of this requirement until the development of this standard. F 2487 provides assurance that the quality of the contractor’s installation techniques was adequate to obtain the specified joint quality in the field.”

According to Kurdziel, F 2487 can be used on any project in which concerns exist regarding infiltration or exfiltration of soils or water. Infiltration of materials into a pipeline can undermine the integrity of the backfill of the pipe and any pavement or structure above it, while exfiltration of water can contaminate the ground, depending on the constituents of the flow (for example, salts or oils).

The purpose of F 2510/F 2510M is to provide tighter criteria for the joint performance of structure-to-pipe connections in order to prevent infiltration into the pipeline that could result in settlement or collapse of the pavement around the structures. “Until the adoption of this standard, there were no ASTM standards to assess the integrity of any of the corrugated polyethylene pipe-to-concrete structure connections,” says Kurdziel. “F 2510/F 2510M addresses gasketed connections that can accommodate settlement or movement around a structure without loss of sealing capability.”

Specification F 2510/F 2510M will be useful on projects in which there is a possibility of infiltration or exfiltration of soils or water at a corrugated HDPE pipe-to-manhole connection. “Many of the structural failures of pipelines occur at the manholes due to either rigid connections that eventually leak or poorly designed systems that do not accommodate typical field deflections,” says Kurdzeil.

Municipalities, transportation departments, specifying engineers, owners and developers will all benefit from both F 2487 and F 2510/F 2510M.
