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. Scope Scope*1.1 This specification cov
3、ers reinforced concrete pipe designed for specific D-loads and intended to be used for the conveyanceof sewage, industrial wastes, and storm water and for the construction of culverts.1.2 This specification is the inch-pound companion to Specification C655M; therefore, no SI equivalents are presente
4、d in thisspecification. Reinforced concrete pipe that conform to the requirements of C655M are acceptable under this Specification C655unless prohibited by the Owner.NOTE 1Experience has shown that the successful performance of this product depends upon the proper selection of the pipe strength, the
5、 type ofbedding and backfill, the care that the installation conforms to the construction specifications, and provision for adequate inspection at the constructionsite. This specification does not include requirements for bedding, backfill, the relationship between field load conditions and the stre
6、ngth designation ofpipe, or durability under unusual environmental conditions. These requirements should be included in the project specification.1.3 This international standard was developed in accordance with internationally recognized principles on standardizationestablished in the Decision on Pr
