ASTM F2418-25

Annotation of standard text ASTM F2418-25 :

This specification covers requirements, test methods, materials, and marking for polypropylene (PP), open bottom, buried chambers of corrugated wall construction used for collection, detention, and retention of stormwater runoff. Applications include commercial, residential, agricultural, and highway drainage, including installation under parking lots and roadways. Chambers are produced in arch shapes with dimensions based on chamber rise, chamber span, and wall stiffness. They are manufactured with integral feet that provide base support. They may include perforations to enhance water flow and must meet test requirements for arch stiffness, flattening, and accelerated weathering. The successful performance of the product depends upon the type and depth of bedding and backfill, and care in installation. This specification includes requirements for the manufacturer to provide chamber installation instructions to the purchaser.
