(Specification)Standard Specification for Polyethylene (PE) Corrugated Wall Stormwater Collection Chambers
Standard Specification for Polyethylene (PE) Corrugated Wall Stormwater Collection Chambers
ABSTRACT
This specification covers requirements, test methods, materials, and marking for polyethylene (PE), open bottom, buried arch-shaped chambers of corrugated wall construction used for collection, detention, and retention of stormwater runoff. These collection chambers can be used as commercial, residential, agricultural, and highway drainage, including installation under parking lots and roadways. This specification indicates the classifications, tolerances, and dimensions of the chambers. It also lists the test methods that examine the physical and mechanical properties of finished chambers.
SCOPE
1.1 This specification covers requirements, test methods, materials, and marking for polyethylene (PE), open bottom, buried arch-shaped 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.
1.2 Chambers are produced in arch shapes with dimensions based on chamber rise, chamber span, and wall stiffness. Chambers are manufactured with integral feet that provide base support. Chambers may include perforations to enhance water flow. Chambers must meet test requirements for arch stiffness, flattening, and accelerated weathering.
1.3 Analysis and experience have shown that the successful performance of this 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.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 The following safety hazards caveat pertains only to the test method portion, Section 6, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 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.
