ASTM D8107-25a

1.1 This practice covers the setting up and running of a test to determine the clear water flow rate at various depths of a floating sediment pond skimmer.This practice is limited to large-scale test conditions, and does not address hydraulic modeling or pipe-flow based calculations.

1.2 The values stated in SI units are to be regarded as the standard. Reporting of test results in units other than SI shall not be regarded as nonconformance with this standard.

1.3 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026, unless superseded by this standard.

1.4 This practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process.

1.5 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.

5.1 This practice covers the guidelines, requirements and procedures for evaluating the flow rate of a floating sediment pond skimmer versus pond depth. This practice refers to large-scale testing procedures, and is patterned after conditions typically found on construction sites within a sediment basin. This practice outlines test preparation, test execution, data collection, data analysis and reporting procedures for any size calibrated basin.
