This specification covers the testing and requirements fof polymer concrete pipes of specified lengths, intended for use in gravity-flow systems for conveying sanitary sewage, storm water, and industrial wastes. Although this specification is suited primarily for pipes to be installed by direct burial and pipe jacking, it may be used to the extent applicable for other installations such as slip-lining and rehabilitation of existing pipelines. Materials shall be appropriately sampled for purposes of testing their conformance to such requirements as: workmanship; dimension (diameter, length, thickness, straightness, roundness, and squareness of ends); three-edge bearing; hydrostatic pressure; compressive strength; chemical resistance; and joint tightness.
