Designation:D646199(Reapproved 2007)2Standard Specification forSilt Fence Materials1This standard is issued under the fixed designation D6461;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.1NOTEEditorial changes were made throughout in November 2007.2NOTEReference to Terminology D653 added in March 2008.1.Scope1.1 This specification covers requirements and test methodsfor geotextile fabrics and associated components used intemporary silt fence applications.This is a material purchasingspecification based on AASHTO M288.1.2 This specification is applicable to the use of a geotextileas a vertical permeable interceptor designed to remove sus-pended soil from overland,nonconcentrated water flow.Thefunction of a temporary silt fence is to trap and allowsettlement of soil particles from sediment laden water.Thepurpose is to greatly limit the transport of eroded soil from thea construction site by water runoff.1.3 The tests used to characterize the silt fence are intendedto ensure good workmanship and quality and are not necessar-ily adequate for design purposes in view of the wide variety ofpossible sediments and performance objectives.1.4 The values stated in SI units are to be regarded as thestandard.The values in inch-pound units are provided forinformation only.2.Referenced Documents2.1 ASTM Standards:2D123 Terminology Relating to TextilesD276 Test Methods for Identification of Fibers in TextilesD653 Terminology Relating to Soil,Rock,and ContainedFluidsD4354 Practice for Sampling of Geosynthetics for TestingD4355 Test Method for Deterioration of Geotextiles byExposure to Light,Moisture and Heat in a Xenon ArcType ApparatusD4439 Terminology for GeosyntheticsD4491 Test Methods for Water Permeability of Geotextilesby PermittivityD4632 Test Method for Grab Breaking Load and Elongationof GeotextilesD4751 Test Method for DeterminingApparent Opening Sizeof a GeotextileD4759 Practice for Determining the Specification Confor-mance of GeosyntheticsD4873 Guide for Identification,Storage,and Handling ofGeosynthetic Rolls and SamplesD5141 Test Method for Determining Filtering Efficiency andFlow Rate of the Filtration Component of a SedimentRetention Device2.2 AASHTO Standard:M288-96 Standard Specification for Geotextile Specifica-tion for Highway Applications33.Materials and Manufacture3.1 Fibers used in the manufacture of geotextiles for siltfence,and the threads used in joining geotextiles by sewing,shall consist of long-chain synthetic polymers composed of atleast 95%by weight of polyolefins or polyester.They shall beformed into a stable network such that the filaments or yarnsretain their dimensional stability relative to each other,includ-ing selvages.3.2 Geotextiles and related materials used for temporary siltfence shall conform with the physical requirements of Sections7 and 8.3.3 All property values,with the exception of apparentopening size(AOS),in this specification represent minimumaverage roll values(MARV)in the weakest principle direction(that is,average test results of any roll in a lot sampled forconformance or quality assurance testing shall meet or exceedthe minimum value provided herein).Values forAOS representmaximum average roll values.1This specification is under the jurisdiction of ASTM Committee D18 on Soiland Rock and is the direct responsibility of Subcommittee D18.25 on Erosion andSediment Control Technology.Current edition approved Nov.1,2007.Published November 2007.Originallyapproved in 1999.Last previous edition approved in 1999 as D6461 99.DOI:10.1520/D6461-99R07E02.2For 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 Association of State Highway and TransportationOfficials(AASHTO),444 N.Capitol St.,NW,Suite 249,Washington,DC 20001,http:/www.transportation.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.Sampling,Testing,and Acceptance4.1 Silt fence shall be subject to sampling and testing toverify conformance with this specification.Sampling for test-ing shall be in accordance with Practice D4354.Acceptanceshall be based on testing of either conformance samplesobtained using Procedure A of Practice D4354,or based onmanufacturers certifications and testing of quality assurancesamples obtained using Procedure B of Practice D4354.A lotsize for conformance or quality assurance sampling shall beconsidered to be the shipment quantity of the given product ora truckload of the given product,whichever is smaller.4.2 Testing shall be performed in accordance with the testmethods referenced in
