Manufactured drain tile shall be of the following classes: standard-quality concrete drain tile, extra-quality concrete drain tile, heavy-duty extra-quality concrete drain tile, and special-quality concrete drain tile. The concrete shall consist of mineral aggregates, water, and cementitious materials that include Portland cement, fly ash, ground granulated blast furnace slag, aggregates, admixtures and blends, and synthetic fibers. Concrete drain tile shall meet the physical requirement of the specification according to class, depending on soil acidity and sulfate content. Test specimens shall meet the external load crushing strength test requirement of the specification.

1.1 This specification covers concrete drain tile with internal diameters from 100 to 900 mm, that are intended to be used for surface and subsurface drainage. 1.2 This specification is the metric counterpart of Specification C412. Note 1: This specification is a manufacturing and purchase
specification only and does not include requirements for bedding,
backfill, or the relationship between field load condition and the
strength classification of drain tile. However, experience has
shown that the successful performance of 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 the
construction specifications. The owner is cautioned that he must
correlate the field requirements with the class of drain tile
specified and provide for or require inspection at the construction
site.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
