1、Designation: C 985M 04e1METRICStandard Specification forNonreinforced Concrete Specified Strength Culvert, StormDrain, and Sewer Pipe Metric1This standard is issued under the fixed designation C 985M; the number immediately following the designation indicates the year oforiginal adoption or, in the
2、case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.e1NOTEEditorial changes were made throughout in March 2005.1. Scope1.1 This specification covers no
3、nreinforced concrete pipedesigned for specified strengths and intended to be used for theconveyance of sewage, industrial wastes, and storm water andfor the construction of culverts.1.2 This specification is the metric counterpart of Specifi-cation C 985.NOTE 1This specification is a manufacturing a
4、nd purchase specifica-tion only and does not include requirements for bedding, backfill, or therelationship between field load conditions and the designated strength ofthe pipe. However, experience has shown that the successful performanceof this product depends upon the proper selection of the pipe
5、 strength, typeof bedding and backfill, and care that the installation conforms to theconstruction specifications. The owner of the concrete pipe specifiedherein is cautioned that he must correlate the field requirements with thepipe strength specified and provide inspection at the construction site
