1、Designation: C412 11Standard Specification forConcrete Drain Tile1This standard is issued under the fixed designation C412; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicate
2、s the year of last reapproval. Asuperscript epsilon () 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 concrete drain tile with inter-nal diameters from 4 to 36
3、in. that are intended to be used forsurface and subsurface drainage.1.2 Acomplete metric companion to Specification C412 hasbeen developedC412M; therefore, no metric equivalents arepresented in this specification.NOTE 1This specification is a manufacturing and purchase specifica-tion only and does n
4、ot include requirements for bedding, backfill, or therelationship between field load condition and the strength classification ofdrain tile. However, experience has shown that the successful performanceof the product depends upon the proper selection of the class of drain tile,type of bedding and ba
5、ckfill, and care that the installation conforms to theconstruction specifications. The owner is cautioned that he must correlatethe field requirements with the class of drain tile specified and provide foror require inspection at the construction site.2.
