1、Designation: C 506M 07METRICStandard Specification forReinforced Concrete Arch Culvert, Storm Drain, and SewerPipe Metric1This standard is issued under the fixed designation C 506M; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, t
2、he 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.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This specification covers
3、 reinforced arch-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 metric counterpart of Specifi-cation C 506.NOTE 1This specification is a manufacturing and purchase specifica-tion only, a
4、nd does not include requirements for bedding, backfill, or therelationship between field load condition and the strength classification ofpipe. However, experience has shown that the successful performance ofthis product depends upon the proper selection of the class of pipe, typeof bedding and back
5、fill, 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 constructionsite.2.
