3、rs reinforced 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 i
4、s a manufacturing 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 se
