2、 of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers polymer concrete pipe, 6 in.(150 mm) through 144 in. (3 660 mm), intended for use ingrav

3、ity-flow systems for conveying sanitary sewage, stormwater, and industrial wastes.1.2 Although this specification is suited primarily for pipe tobe installed by direct burial and pipe jacking, it may be used tothe extent applicable for other installations such as slipliningand rehabilitation of exis

4、ting pipelines.NOTE 1Unlike reinforced thermosetting resin pipes, polymer con-crete pipe is designed and installed using rigid pipe design theory andpractices.1.3 The values stated in inch-pound units are to be regardedas the standard. The values given in parentheses are forinformation only.1.4 The

5、following safety hazards caveat pertains only to thetest methods portion, Section 8, of this specification. Thisstandard may involve hazardous materials, operations, andequipment. This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsib

6、ility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory requirements prior to use.NOTE 2There is no known ISO equivalent to this standard.2.

49、116 in. (1 mm) or less. Lay the tape orgage on or inside the pipe and measure the overall length of thepipe.8.1.3 Wall-ThicknessDetermine in accordance with Prac-tice D3567.8.1.4 Straightness of PipePlace a straight edge along theentire length of the pipe barrel. Measure the maximum devia-tion from straightness. Take four measurements at 90 intervalsaround the pipe and report the maximum deviation.8.1.5 Roundness of PipeMeasure the maximum and mini-mum outside diameters at one location on the joint sealingsurface of the pipe.
