Designation:D805717Standard Specification forInlet Filters with a Rigid Frame1This standard is issued under the fixed designation D8057;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 specification covers geosynthetic storm sewer inletfilters used in highway drainage,roadway,residential,commercial,and industrial applications.The inlet filter iscomprised of a rigid frame and a removable geosyntheticsediment bag.The sediment bag hangs suspended from therigid frame and includes a bypass that shall allow water flowinto the drainage structure if the bag is completely filled withsediment.Water flow through the bypass shall equal or exceedthe design flow of the inlet required at a specified drainagelocation.1.2 The requirements of this specification are intended toprovide an inlet filter system to collect sediment,trash,leaves,and other storm water contaminants from surface storm waterrunoff at drainage inlet locations during temporary site con-struction.1.3 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 and health practices and determine the applica-bility of regulatory limitations prior to use.1.4 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:2D4439 Terminology for GeosyntheticsD5141 Test Method for Determining Filtering Efficiency andFlow Rate of the Filtration Component of a SedimentRetention DeviceD7351 Test Method for Determination of Sediment Reten-tion Device Effectiveness in Sheet Flow Applications2.2 AASHTO Standards:3AASHTO M288 Geotextile Materials3.Terminology3.1 Definitions:3.1.1 For definitions of terms relating to geosynthetics,referto Terminology D4439.3.2 Definitions of Terms Specific to This Standard:3.2.1 design flow rate of the inlet,nthe design flow to thedrainage structure.3.2.2 treatment flow rate,nthe design flow that is intendedto be filtered through the sediment bag.4.Classification4.1 GeneralThis specification covers geosynthetic stormsewer inlet filters used in highway drainage,roadway,residential,commercial,and industrial applications.The inletfilter is comprised of a rigid frame and a removable geosyn-thetic sediment bag fixed to the frame by a positive connectionwith adequate strength to support the weight of the sedimentbag when completely full.4.2 This product can be used with round,rectangular,gutter,rolled curb,and curb inlet types.5.Ordering Information5.1 When ordering material in accordance with thisspecification,the following should be specified:5.1.1 The inlet type,grate length and width,or diameter,5.1.2 The inlet clear opening length and width,or diameter,5.1.3 The frame materials,5.1.4 The geosynthetic bag physical properties,5.1.5 The geosynthetic bag volume capacity,5.1.6 The treatment flow rate,and5.1.7 The design flow rate of the inlet.6.Materials and Manufacture6.1 Basic MaterialsThese products are comprised of arigid frame and geosynthetic sediment bag.The sediment bag1This specification 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 May 1,2017.Published May 2017.Originallyapproved in 2017.DOI:10.1520/D8057-17.2For 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 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 must be sized appropriately to meet the treatment flow raterequired.The sediment bag hangs suspended from the rigidframe and includes a bypass that shall allow water flow into thedrainage structure if the bag is completely filled with sediment.Water flow through the bypass shall equal or exceed the designflow of the inlet r
