Designation:D556794(Reapproved 2018)Standard Test Method forHydraulic Conductivity Ratio(HCR)Testing of Soil/Geotextile Systems1This standard is issued under the fixed designation D5567;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 covers laboratory measurement of thehydraulic conductivity of water-saturated porous materialswith a flexible-wall permeameter.1.2 This test method may be used with undisturbed orcompacted soil specimens that have a hydraulic conductivityless than or equal to 5 102cm/s.1.3 The filtration behavior of soils with hydraulic conduc-tivities greater than 5 102cm/s may be determined by thegradient ratio test(Test Method D5101).1.4 The values stated in SI units are to be regarded as thestandard,although other units are provided for information andclarification purposes.1.5 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.1.6 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:2D422 Test Method for Particle-Size Analysis of Soils(With-drawn 2016)3D653 Terminology Relating to Soil,Rock,and ContainedFluidsD698 Test Methods for Laboratory Compaction Character-istics of Soil Using Standard Effort(12,400 ft-lbf/ft3(600kN-m/m3)D854 Test Methods for Specific Gravity of Soil Solids byWater PycnometerD1587/D1587M Practice for Thin-Walled Tube Sampling ofFine-Grained Soils for Geotechnical PurposesD2216 Test Methods for Laboratory Determination of Water(Moisture)Content of Soil and Rock by MassD2487 Practice for Classification of Soils for EngineeringPurposes(Unified Soil Classification System)D2488 Practice for Description and Identification of Soils(Visual-Manual Procedures)D4220/D4220M Practices for Preserving and TransportingSoil SamplesD4318 Test Methods for Liquid Limit,Plastic Limit,andPlasticity Index of SoilsD4354 Practice for Sampling of Geosynthetics and RolledErosion Control Products(RECPs)for TestingD4439 Terminology for GeosyntheticsD4491/D4491M Test Methods for Water Permeability ofGeotextiles by PermittivityD4647/D4647M Test Methods for Identification and Classi-fication of Dispersive Clay Soils by the Pinhole TestD4751 Test Methods for Determining Apparent OpeningSize of a GeotextileD5084 Test Methods for Measurement of Hydraulic Con-ductivity of Saturated Porous Materials Using a FlexibleWall PermeameterD5101 Test Method for Measuring the Filtration Compat-ibility of Soil-Geotextile Systems3.Terminology3.1 Definitions:3.1.1 filter,na layer or combination of layers of previousmaterials designed and installed in such a manner as to providedrainage,yet prevent the movement of soil particles due toflowing water.(Terminology D653.)3.1.1.1 DiscussionA geotextile filter is the term used for alayer or combination of layers of pervious geosynthetic mate-rial(s)that are used in the capacity of a filter as defined above.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 June 1,2018.Published June 2018.Originallyapproved in 1994.Last previous edition approved in 2011 as D5567 94(2011).DOI:10.1520/D5567-94R18.2For 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.3The last approved version of this historical standard is referenced onwww.astm.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 3.1.2 geotextile,nany permeable textile material usedwith foundation,soil,rock,earth,or any other geotechnicalengineering-related material,as an integral part of a manmadeproduct,structure,or system.(Terminology D4439.)3.1.3 hydraulic conductivity(k),nthe rate of discharge ofwater under laminar flow conditions th
