2、f last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () 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 reinforce
3、d arch-shaped concrete pipe to be used for the conveyance of sewage, industrial wastes,storm water, and for the construction of culverts.1.2 This specification is the inch-pound companion to C506M; therefore, no SI equivalents are presented in the specification.NOTE 1This specification is a manufact
4、uring and purchase specification only, and does not include requirements for bedding, backfill, or therelationship between field load condition and the strength classification of pipe. However, experience has shown that the successful performance of thisproduct depends upon the proper selection of t
5、he class of pipe, type of bedding and backfill, and care that the installation conforms to the constructionspecifications. The owner of the reinforced concrete pipe specified herein is cautioned that he must correlate the field requirements with the class of pipespecified and provide inspection at t
