Designation:D6151/D6151M15Standard Practice forUsing Hollow-Stem Augers for Geotechnical Exploration andSoil Sampling1This standard is issued under the fixed designation D6151/D6151M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice covers how to obtain soil samples usingHollow-Stem Auger(HSA)sampling systems and use ofhollow-stem auger drilling methods for geotechnical explora-tion.This practice addresses how to obtain soil samplessuitable for engineering properties testing.1.2 In most geotechnical explorations,Hollow-Stem Auger(HSA)drilling is combined with other sampling methods.Splitbarrel penetration tests(Test Method D1586)are often per-formed to provide estimates of engineering properties of soils.Thin-wall tube(Practice D1587)and ring-lined barrel samples(Practice D3550)are also frequently taken.This practicediscusses hole preparation for these sampling events.Forinformation on the sampling process,consult the relatedstandards.Other in situ tests,such as the vane shear TestMethod D2573,can be performed below the base of the boringby access through the drill string.Other drilling methods aresummarized in Guide D6286.Practice D1452 describes solidstem augers.1.3 This practice does not include considerations for geoen-vironmental site characterizations and installation of monitor-ing wells which are addressed in Guide D5784.1.4 This practice offers a set of instructions for performingone or more specific operations.This document cannot replaceeducation or experience and should be used in conjunction withprofessional judgment.Not all aspects of this practice may beapplicable in all circumstances.This ASTM standard is notintended to represent or replace the standard of care by whichthe adequacy of a given professional service must be judged,nor should this document be applied without consideration ofa projects many unique aspects.The word“Standard”in thetitle of this practice means only that the document has beenapproved through the ASTM consensus process.1.5 All observed and calculated values shall conform to theguidelines for significant digits and rounding established inPractice D6026,unless superseded by this standard.1.6 The values stated in either inch-pound units or SI unitspresented in brackets are to be regarded separately asstandard.The values stated in each system may not be exactequivalents;therefore,each system shall be used independentlyof the other.Combining values from the two systems mayresult in non-conformance with the standard.1.7 Hollow-stem auger drilling for geotechnical explorationoften involves safety planning,administration,and documen-tation.This standard does not purport to specifically addressexploration and site safety.It is the responsibility of the user ofthis standard to establish appropriate safety and health prac-tices and determine the applicability of regulatory limitationsprior to its use.Performance of the test usually involves use ofa drill rig,therefore,safety requirements as outlined inapplicable safety standards,for example OSHA(OccupationalHealth and Safety Administration)regulations,DCDMA safetymanual(1),2drilling safety manuals,and other applicable stateand local regulations must be observed.2.Referenced Documents2.1 ASTM Standards:3D420 Guide to Site Characterization for Engineering Designand Construction Purposes(Withdrawn 2011)4D653 Terminology Relating to Soil,Rock,and ContainedFluidsD2488 Practice for Description and Identification of Soils(Visual-Manual Procedure)D3740 Practice for Minimum Requirements for AgenciesEngaged in Testing and/or Inspection of Soil and Rock asUsed in Engineering Design and Construction1This practice is under the jurisdiction of ASTM Committee D18 on Soil andRock and is the direct responsibility of Subcommittee D18.02 on Sampling andRelated Field Testing for Soil Evaluations.Current edition approved July 1,2015,Published July 2015.Originally approvedin 1997.Last previous edition approved in 2008 as D6151 08.DOI:10.1520/D6151_D6151M-15.2The boldface numbers in parentheses refer to the references at the end of thispractice.3For 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.4The 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 States1 D5434 Guide for Field Logging of Subsurface Explorationsof Soil and RockD6026 Practice for Using Significant Digits in GeotechnicalData2.2 Standards for Sampling of Soil and Rock:D1452 Practice for Soil Exploration and Sampling
