3、pe1.1 This performance based specification covers reinforcedconcrete pipe intended to be used for the conveyance ofsewage, industrial wastes, and storm water, and for the con-struction of culverts.1.2 It is not the intention of this standard to dictate thematerial quantities and properties required
4、for a pipe toconform to this standard except those in Section 6. Specificproduct formulations shall be considered proprietary andallowed to remain confidential to the manufacturer.NOTE 1This specification is a manufacturing and purchase specifica-tion only, and does not include requirements for bedd
5、ing, 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 care that installation conforms
6、 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.NOTE 2Attention is called to the specification for Reinforced Con-cr
7、ete D-load Culvert, Storm Drain, and Sewer Pipe (Specification C655).The distinction between this specification and C655 is in the D-Loadspecified and the practice for sampling pipe for conformance to thespecification. This specification relies on standard classes of pipe (ClassI-V), and sampling in
