Scope1.1 This specification covers re
3、inforced 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 SI companion to SpecificationC 506.NOTE 1This specification is a manufacturing and purchase specifica-tion only, and does not
4、 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 backfill, and c
5、are 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.
