(Specification)Standard Specification for Nonreinforced Concrete Sewer, Storm Drain, and Culvert Pipe (Metric)
Standard Specification for Nonreinforced Concrete Sewer, Storm Drain, and Culvert Pipe (Metric)
ABSTRACT
This specification covers nonreinforced concrete sewer, storm drain, and culvert pipe. The pipe manufactured according to this specification shall be of three classes: Class 1, Class 2, and Class 3. The strength requirements for nonreinforced concrete pipe are specified. The concrete shall consist of cementitious material, mineral aggregates, and water. Cementitious materials are the following: cement, fly ash, ground granulated blast furnace slag, and allowable combinations of cementitious materials. The design of the pipe may be according to design tables or modified or special design. The following are the processes for pipe manufacturing: mixture; curing such as pipe curing, water curing, and membrane curing; and specials like shapes or fittings and fabricated branches. The following tests shall be made: strength test, absorption test, permeability test, and hydrostatic test.
SCOPE
1.1 This specification covers nonreinforced concrete pipe intended to be used for the conveyance of sewage, industrial wastes, storm water, and for the construction of culverts.
1.2 This specification is the metric counterpart of Specification C14.
Note 1: This specification is a manufacturing and purchase specification only and does not include requirements for bedding, backfill, or the relationship between field load condition and the strength classification of pipe. However, experience has shown that the successful performance of this product depends upon the proper selection of the class of pipe, type of bedding and backfill, and care that the installation conforms to the construction specifications. The owner is cautioned that he must correlate the field requirements with the class of pipe specified and provide for or require inspection at the construction site.

diameter. Joints shall be compatible with those used in adjoining concrete pipes.
9.3.2 Fabricated Branches—Fabricated branches for wyes and tees shall be securely attached to the wall of the pipe in such a
manner as not to restrict or otherwise interfere with the flow characteristics of the pipe.
10. Physical Requirements
10.1 Test Specimen—The specified number of pipe required for the tests shall be furnished by the manufacturer and shall be
selected at random by the owner, and shall be pipe that would not otherwise be rejected under this specification. The selection shall
be made at the point or points designated by the owner when placing the order. The test pipe shall first be freed from all visible
moisture. When dry, each pipe shall be measured and inspected. The results of these observations shall be recorded.
10.2 Number and Type of Test Specimens Required—The manufacturer or seller shall furnish pipe for crushing and absorption
tests, up to 0.5 % of the number of pipe of each size included in the order, except that in no case shall less than two pipe be
furnished. For the permeability test, 2 % of the number of pipe of each size included in the order, but in no case less than two pipe
shall be furnished. For the hydrostatic test, 0.5 % of the number of pipe of each size included in the order, but in no case less than
two pipe shall be furnished.
10.3 External Load Crushing Requirement—The crushing strength of nonreinforced concrete pipe shall conform to the
requirements prescribed in Table 1. The individual results of the various tests for each size of pipe and for each shipment and plant
shall be tabulated separately. The crushing strength shall ordinarily be applied to not less than 75 % of the pipe received for purpose
of test. All tests shall be made in accordance with Test Method C497M. Pipe shall be acceptable when all test pipe conform to the
specified requirement. Should any of the test pipe provided in 10.2 fail to meet the strength requirement, the manufacturer will be
allowed to test two pipe for each pipe that failed, and the pipe shall be acceptable only when all of these additional test pipe meet
the strength requirement.
10.4 Absorption Requirement—When required by the owner, an absorption test shall be performed by either Test Method A or
Test Method B in accordance with Test Methods C497M for the boiling absorption test. Absorption shall not exceed 9 % for Test
C14M − 15
Method A or 8.5 % for Test Method B. The individual results of the various tests for each size of pipe and for each shipment and
plant shall be tabulated separately. All tests shall be made in accordance with Test Methods C497M. The number of absorption test
specimens shall be equal to the number of pipe provided for crushing strength testing. These specimens shall be obtained from pipe
that are acceptable as to strength, and shall be taken from pipe used in making the strength test after the test is made. These
specimens shall be marked with the number or identification mark of the pipe from which they were taken. Each Test Method A
specimen shall have an area of 77 to 129 cm , as measured on one surface of the pipe, and a thickness equal to the pipe wall, and
shall be free of visible cracks. Pipe shall be acceptable when all test pipe conform to the specified absorption requirements.
10.5 Permeability Requirement—When subjected to the permeability test, as specified in Test Methods C497M, the outer pipe
surface of not less than 80 % of the pipe tested shall show no moist or damp spots at the end of the test period due to water passing
through the walls of the pipe.
10.6 Hydrostatic Requirement—When subjected to the hydrostatic test, as described in Test Methods C497M, the pipe shall
show no leakage during 10 min at 70 kPa. Moisture appearing on the surface of the pipe in the form of patches or beads adhering
to the surface shall not be considered leakage. The test pipe shall be filled with water and held under
