ASTM C985-04

1.1 This specification covers nonreinforced concrete pipe designed for specified strengths and intended to be used for the conveyance of sewage, industrial wastes, and storm water and for the construction of culverts.

1.2 A complete companion to Specification C 985 has been developed, C 985M; therefore, no metric equivalents are presented in this specification. Note 1This specification is a manufacturing and purchase specification only and does not include requirements for bedding, backfill, or the relationship between field load conditions and the designated strength of the pipe. However, experience has shown that the successful performance of this product depends upon the proper selection of the pipe strength, type of bedding and backfill, and care that the installation conforms to the construction specifications. The owner of the concrete pipe specified herein is cautioned that he must correlate the field requirements with the pipe strength specified and provide inspection at the construction site.
