Designation:D729920Standard Practice forVerifying Performance of a Vertical Inclinometer Probe1This standard is issued under the fixed designation D7299;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.Scope*1.1 This practice describes three function tests that togethercan be used to verify that a vertical traversing inclinometerprobe is working properly.1.2 This practice does not address calibration routines,electronic diagnostics,or repair of the probe,nor does itaddress inspection of the probes mechanical parts.1.3 This practice is not intended to replace manufacturersrecommendations for servicing and calibration of inclinometerequipment,nor is it intended to replace maintenance andcalibration schedules established by users as part of theirquality programs.1.4 UnitsThe values stated in SI units are to be regardedas standard.No other units of measurement are included in thisstandard.1.5 All observed and calculated values shall conform to theguidelines for significant digits and rounding established inPractice D6026.1.6 This practice offers a set of instructions for performingone or more specific operations.This document cannot replaceeducation or experience and should be used in conjunctionwith professional judgment.Not all aspects of this practice maybe applicable 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 document means only that the document has beenapproved through the ASTM consensus process.1.7 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.1.8 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 ConstructionD6026 Practice for Using Significant Digits in GeotechnicalData3.Terminology3.1 For definitions of common technical terms used in thisstandard,refer to Terminology D653.3.2 Definitions of Terms Specific to This Standard:3.2.1 inclinometer casing,na special-purpose pipe,typi-cally installed in boreholes,with internal guide grooves thatcontrol the orientation of the inclinometer probe and thatprovide a flat surface for repeatable tilt measurements.3.2.2 inclinometer survey,na set of readings obtainedwith the inclinometer probe and readout.3.2.3 vertical inclinometer probe,nan instrument com-prised of a downhole probe which uses internal sensors todetect its own orientation relative to the force of gravity,witha wheel assembly for lowering into the inclinometer casingalong the alignment grooves,connected by a cable to a readoutor datalogger at the surface.3.2.4 zero offset,nnon-zero values reported by the A-axisand B-axis sensors when the probe is held precisely vertical.4.Significance and Use4.1 Inclinometer monitoring programs often run severalyears or more.During this time,hundreds of surveys can becollected.Each new survey is processed by comparing it to abaseline survey.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 Nov.1,2020.Published November 2020.Originallyapproved in 2006.Last previous edition approved in 2012 as D7299 12.DOI:10.1520/D7299-20.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandardsvolume 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 T
