Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope1.1 This specification covers r
3、einforced concrete pipe intended to be used for the conveyance of sewage, industrial wastes, andstorm water, and for the construction of culverts.1.2 This specification is the SI companion to Specification C76. ; therefore, no inch-pound equivalents are presented in thisspecification. Reinforced con
4、crete pipe that conform to the requirements of C76 are acceptable under this Specification C76Munless prohibited by the Owner.NOTE 1This specification is a manufacturing and purchase specification only, and does not include requirements for bedding, backfill, or therelationship between field load co
5、ndition and the strength classification of pipe. However, experience has shown that the successful performance of thisproduct depends upon the proper selection of the class of pipe, type of bedding and backfill, controlled manufacture in the plant, and care and installationconforms to the constructi
6、on specifications. The owner of the reinforced concrete pipe specified herein is cautioned that he must correlate the fieldrequirements with the class of pipe specified and provide inspection at the construction site.NOTE 2Attention is called to the specification for reinforced concrete D-load culve
