(Specification)Standard Specification for Polymer Concrete Pipe
Standard Specification for Polymer Concrete Pipe
ABSTRACT
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.
SCOPE
1.1 This specification covers polymer concrete pipe, 6 in. (150 mm) through 144 in. (3 660 mm), intended for use in gravity-flow systems for conveying sanitary sewage, storm water, and industrial wastes.
1.2 Although this specification is suited primarily for pipe to be installed by direct burial and pipe jacking, it may be used to the extent applicable for other installations such as sliplining and rehabilitation of existing pipelines.
Note 1: Unlike reinforced thermosetting resin pipes, polymer concrete pipe is designed and installed using rigid pipe design theory and practices.
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 The following safety hazards caveat pertains only to the test methods portion, Section 8, of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 2: There is no known ISO equivalent to this standard.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
