Designation:D514111(Reapproved 2018)Standard Test Method forDetermining Filtering Efficiency and Flow Rate of theFiltration Component of a Sediment Retention Device1This standard is issued under the fixed designation D5141;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method is used to determine the filteringefficiency and the flow rate of the filtration component of asediment retention device,such as a silt fence,silt barrier,orinlet protector.1.1.1 The results are shown as a percentage for filteringefficiency and cubic metres per square metre per minute(m3/m2/min)or gallons per square foot per minute(gal/ft2/min)for flow rate.1.1.2 The filtering efficiency indicates the percent of sedi-ment removed from sediment-laden water.1.1.3 The flow rate is the average rate of passage of thesediment-laden water through the filtration component of asediment retention device.1.2 This test method requires several specialized pieces ofequipment,such as an integrated water sampler and an ana-lytical balance,or a vacuum filtration system.At the clientsdiscretion,the test soil is either a site-specific soil or a soil thatis representative of a target default gradation.1.3 The values stated in SI units are the standard,while theinch-pound units are provided for information.The valuesexpressed in each system may not be exact equivalents;therefore,each system must be used independently of the other,without combining values in any way.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D123 Terminology Relating to TextilesD653 Terminology Relating to Soil,Rock,and ContainedFluidsD4354 Practice for Sampling of Geosynthetics and RolledErosion Control Products(RECPs)for TestingD4439 Terminology for GeosyntheticsD4759 Practice for Determining the Specification Confor-mance of Geosynthetics2.2 American Public Health Association(APHA)Stan-dard:3208D Total Nonfiltrable Residue Dried at 103105C(TotalSuspended Matter)3.Terminology3.1 Definitions:3.1.1 filterSee Terminology D653.3.1.2 filtration componenta geotextile or other materialdesigned to act as a filter.3.1.3 geosynthetic,na planar product manufactured frompolymeric material used with foundation soil,rock,earth,orany other geotechnical engineering related material as anintegral part of a man-made project,structure,or system.(SeePractice D4759.)3.1.4 performance property,na result obtained by con-ducting a performance test.3.1.5 performance test,nin geosynthetics,a laboratoryprocedure that simulates selected field conditions which can beused in design.3.1.6 Fordefinitionsofothertermsrelatingtogeosynthetics,refer to Terminology D4439.For definitions oftextile terms,refer to Terminology D123.For definitions of soilterms,refer to Terminology D653.1This test method is under the jurisdiction of ASTM Committee D35 onGeosynthetics and is the direct responsibility of Subcommittee D35.03 on Perme-ability and Filtration.Current edition approved Feb.1,2018.Published February 2018.Originallyapproved in 1991.Last previous edition approved in 2011 as D5141 11.DOI:10.1520/D5141-11R18.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from American Public Health Association(APHA),1015 EighteenthSt.NW,Washington,DC 20036.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 3.2 Definitions of Terms Specific to This Standard:3.2.1 filtering effciency,FE,nin geosynthetics,the per-cent of sediment removed from sediment-laden water by thefiltration component of a sediment retention device over aspecified period of time.3.2.2 flow rate,FR L3L2T1,nin geosynthetics,thevolume of fluid per unit
