【国外标准】 Standard Practice for Determining Sediment Pond Skimmer Flow Rate

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.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.1.2 This practice is limited to large-scale test conditions, and does not address hydraulic modeling or pipe-flow based calculations.1.3 The values stated in SI units are to be regarded as the standard.1.4 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026, unless superseded by this standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use.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.
