Designation:D6230211Standard Practices forMonitoring Earth or Structural Movement UsingInclinometers1This standard is issued under the fixed designation D6230;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.1NOTEMinor corrections were editorially made throughout in July 2021.1.Scope*1.1 This standard covers the use of inclinometers to monitorthe internal movement of ground,or lateral movement ofsubsurfacestructures.Thestandardcoverstypesofinstruments,installation procedures,operating procedures,andmaintenance requirements.The standard also provides formu-lae for data reduction.1.2 All observed and calculated values shall conform to theguidelines for significant digits and rounding established inPractice D6026 unless superseded by this standard.1.2.1 The procedures used to specify how data are collected,recorded or calculated in this standard are regarded as theindustry standard.In addition,they are representative of thesignificant digits that generally should be retained.The proce-dures used do not consider material variation,purpose forobtaining the data,special purpose studies,or any consider-ations for the users objectives;it is common practice toincrease or reduce significant digits of reported data to becommensurate with these considerations.It is beyond the scopeof this standard to consider significant digits used in analyticalmethods for engineering design.1.3 UnitsThe values stated in SI units are to be regardedas the standard.The inch-pound units given in parentheses arefor information only.Reporting of test results in units otherthan SI shall not be regarded as nonconformance with thisstandard.1.4 This standard offers an organized collection of informa-tion or a series of options and does not recommend a specificcourse of action.This document cannot replace education orexperience and should be used in conjunction with professionaljudgment.Not all aspects of this standard may be applicable inall circumstances.This ASTM standard is not intended torepresent or replace the standard of care by which the adequacyof a given professional service must be judged,nor should thisdocument be applied without consideration of a projects manyunique aspects.The word“Standard”in the title of thisdocument means only that the document has been approvedthrough the ASTM consensus process.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:2D653 Terminology Relating to Soil,Rock,and ContainedFluidsD3740 Practice for Minimum Requirements for AgenciesEngaged in Testing and/or Inspection of Soil and Rock asUsed in Engineering Design and ConstructionD3966/D3966M Test Methods for Deep Foundations UnderLateral LoadD6026 Practice for Using Significant Digits and Data Re-cords in Geotechnical DataD7299 Practice for Verifying Performance of a VerticalInclinometer Probe3.Terminology3.1 For definitions of common technical terms used in thisstandard,refer to Terminology D653.1This practice is under the jurisdiction of ASTM Committee D18 on Soil andRock and is the direct responsibility of Subcommittee D18.23 on Field Instrumen-tation.Current edition approved June 1,2021.Published June 2021.Originallyapproved in 1998.Last previous edition approved in 2013 as D6230 13.DOI:10.1520/D6230-21E01.2For 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.*A Summary of Changes section appears at the end of this standardCopyright 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.13.2 Definitions of Terms Specific to This Standard:3.2.1 inclinometer casing,na(typically segmented)pipeor casing with grooves specific for the type of inclinometerbeing used.3.2.1.1 DiscussionCasing is ty
