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 concrete drain tile with inter-nal diam

3、eters from 100 to 900 mm, that are intended to be usedfor surface and subsurface drainage.1.2 This specification is the metric counterpart of Specifi-cation C 412.NOTE 1This specification is a manufacturing and purchase specifica-tion only and does not include requirements for bedding, backfill, or

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 backfill, and care that the installation conforms to

5、 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.
