Standard Specification for Nonreinforced Concrete Sewer, Storm Drain, and Culvert Pipe
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 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 A complete metric companion to Specification C14 has been developed—C14M; therefore, no metric equivalents are presented in this specification.
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 conditions 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.
1.3 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
