ASTM D6783-05a(2017)

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.

7. Sampling

more than 100, but at least 20, lengths of pipe of each diameter and strength class produced.
7.2 Production Tests—Select one pipe at random from each lot to determine conformance of the material to the workmanship,
dimensional, and physical requirements of 6.1, 6.2, 6.3 and 6.5, respectively.
7.2.1 Pipe Acceptance—If the tested specimen of a designated lot passes the test, the entire lot shall be acceptable. If the tested
specimen of a designated lot fails to pass the test, then five additional specimens from that same lot shall be selected for testing.
If the five additional specimens pass, the lot shall be acceptable. except the one previous failing specimen. If any of the five
additional specimens fail, the entire lot shall be rejected.
7.3 Qualification Tests—Sampling for qualification tests (see 3.2.5) is not required unless otherwise agreed upon between the
purchaser and the manufacturer. Qualification tests shall be conducted for changes in polymer aggregate and manufacturing process
and for changes in pipe joint or gasket geometry. Qualification tests for which a certification and test report shall be furnished when
requested by the purchaser include the following:
