A superscriptepsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This specification covers reinforced concrete pip

3、eintended to be used for the conveyance of sewage, industrialwastes, and storm water, and for the construction of culverts.1.2 This specification is the inch-pound companion toSpecification C76M; therefore, no SI equivalents are presentedin this specification. Reinforced concrete pipe that conform t

4、othe requirements of C76M, are acceptable under this Specifi-cation C76 unless prohibited by the Owner.NOTE 1This specification is a manufacturing and purchase specifica-tion only, and does not include requirements for bedding, backfill, or therelationship between field load condition and the streng

5、th classification ofpipe. However, experience has shown that the successful performance ofthis product depends upon the proper selection of the class of pipe, typeof bedding and backfill, and care that installation conforms to theconstruction specifications. The owner of the reinforced concrete pipe

6、specified herein is cautioned that he must correlate the field requirementswith the class of pipe specified and provide inspection at the constructionsite.NOTE 2Attention is called to the specification for reinforced concreteD-load culvert, storm drain, and sewer pipe (Specification C655).2.

Basis of Acceptance5.1 Unless otherwise designated by the owner at the time of,or before placing an order, there are two separate and alterna-tive bases of

16、 acceptance. Independent of the method ofacceptance, the pipe shall be designed to meet both the 0.01-in.crack and ultimate strength requirements specified in Tables1-5.5.1.1 Acceptance on the Basis of Plant Load-Bearing Tests,Material Tests, and Inspection of Manufactured Pipe for VisualDefects and

17、 ImperfectionsAcceptability of the pipe in alldiameters and classes produced in accordance with 7.1 or 7.2shall be determined by the results of the three-edge bearingtests as defined in 11.3.1; by such material tests as are requiredin 6.2, 6.3, 6.5, and 6.6; by an absorption test of the concretefrom

18、 the wall of the pipe as required in 11.9; and by visualinspection of the finished pipe to determine its conformancewith the accepted design and its freedom from defects.5.1.2 Acceptance on the Basis of Material Tests and Inspec-tion of Manufactured Pipe for Defects and ImperfectionsAcceptability of

19、 the pipe in all diameters and classes producedin accordance with 7.1 or 7.2 shall be determined by the resultsof such material tests as are required in 6.2, 6.3, 6.5, and 6.6;by crushing tests on concrete cores or cured concrete cylinders;by an absorption test of the concrete from the wall of the p
