ASTM E3332-23

Standard Test Method for Determining Trash and/or Debris Capture Performance of Stormwater Control Measures

1.1The scope of this standard is to provide test criteria for the evaluation of Stormwater Control Measures (SCM), especially Manufactured stormwater Treatment Devices (MTDs), for the removal of trash and/or debris greater than 5 mm in at least two dimensions in a laboratory setting. The use of this standard in conjunction with an appropriate verification program allows for the publication of verified reporting for use in gaining certification by Authorities Having Jurisdiction (AHJs).

1.2For the purpose of this method, a Trash Capture Device (TCD) is an SCM that has the capacity to capture and retain trash and or debris. This may be the primary objective of the device or it may be a secondary feature of a device designed primarily as a Hydrodynamic Separator (HDS) or a filter for capturing sediment particles. This protocol does not address the sediment removal of such devices.

1.3Units - The values stated in inch-pound units are to be regarded as standard, except for methods to establish and report sediment concentration and particle size. It is convention to exclusively describe sediment concentration in mg/L and particle size in mm or μm, both of which are SI units. The SI units given in parentheses are mathematical conversions, which are provided for information purposes only and are not considered standard. Reporting of test results in units other than inch-pound units shall not be regarded as non-conformance with this test method.

1.4Acceptance of test results attained according to this specification may be subject to specific requirements set by a Quality Assurance Project Plan (QAPP), a specific verification protocol, or AHJ. It is advised to review one or all of the above to ensure compliance

1.5This 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.

1.6This 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.
