    This specification covers the specification for the nonreinforced concrete pipe to be used for the conveyance of irrigation water with working pressures, including hydraulic transients, and for use in drainage. The design, joint, and concrete mixture of the pipe is detailed. The acceptability of the pipe shall be determined by the results of the tests prescribed in this specification, such as external load test, absorption test, and hydrostatic test.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    1.1 This specification covers nonreinforced concrete pipe to be used for the conveyance of irrigation water with working pressures, including hydraulic transients, as shown in Table 1 and for use in drainage.

    1.2 This specification is the SI counterpart of Specification C118.

    Note 1—This specification is for manufacturing and purchase only and does not include requirements for bedding, backfill, installation, or field repairs. The owner is cautioned that he must correlate field conditions with the characteristics of the pipe specified and provide inspection during installation.

    A For hydrostatic test requirements, refer to 10.5.

    B Higher working pressures are not prohibited up to a maximum of 120 kPa for 150 through 200-mm diameters, 105 kPa for 250 through 300-mm diameters, and 90 kPa for 350 through 600-mm diameters. In these cases, the strength of the pipe shall be increased to give a minimum internal hydrostatic test pressure of at least four times the design working pressure when tested as specified in 10.5.
