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

1.2 This specification is the SI counterpart of Specification C505.

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.

TABLE 1 Standard Dimensions, Working Pressures, and Test Requirements

Designated Internal Diameter, mmWall Thickness,A mmWorking Pressure,B mRequired Hydrostatic Test Pressure,C kPa Minimum Three-Edge-Bearing Load, kN/linear metre
150 19927519.0
200 25927519.5
250 32927520.5
300 38927522.0

450 57927526.5

600 75927529.0

A Thinner walls are not prohibited on pipe units not over 1.22 m in length but the thickness of such walls should be not less than the internal diameter divided by 10.

B With the exception of 525 and 600-mm pipe, higher working pressures are not prohibited to be used up to a maximum of 15 m for 150 through 300-mm diameters and 12 m for 375 through 450-mm diameters. In these cases the strength of the pipe shall be increased to give minimum internal hydrostatic test pressures of at least three times the design working pressure when tested as specified in 10.4.

C For hydrostatic test requirements, refer to 10.4.
