Standard Specification for Porous Concrete Pipe (ASTM Designation C 654M-05a and C 654-05a)
standard by American Association of State and Highway Transportation Officials, 2007
This specification covers porous nonreinforced concrete pipe for use in underdrains.
This specification agrees with ASTM C 654M-05a and C 654-05a except that the absorption test is limited to the 5-h boil method, the manufacturer is not afforded the option to supply inch-pound sized pipe when the order is placed in SI units, and the use of fibers in Section 6.5 is at the owner’s option.
