2、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 reinforced arch-
3、shaped con-crete pipe to be used for the conveyance of sewage, industrialwastes, storm water, and for the construction of culverts.1.2 This specification is the inch-pound companion toC506M; therefore, no SI equivalents are presented in thespecification.NOTE 1This specification is a manufacturing an

However, experience has shown that the successful performance ofthis product depends upon the proper selection of the class
5、 of pipe, typeof bedding and backfill, and care that the installation conforms to theconstruction specifications. The owner of the reinforced concrete pipespecified herein is cautioned that he must correlate the field requirementswith the class of pipe specified and provide inspection at the constru
