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
