Designation:F179718Standard Test Method forAcoustic Emission Testing of Insulated and Non-InsulatedDigger Derricks1This standard is issued under the fixed designation F1797;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 a procedure for acoustic emis-sion(AE)testing of digger derricks.1.1.1 Equipment CoveredThis test method applies to spe-cial multipurpose vehicle-mounted machines,commonlyknown as digger derricks.These machines are primarilydesigned to dig holes,set poles,and position materials andapparatus.1.1.1.1 Insulated and non-insulated type digger derricksmay be evaluated with this test method.1.1.1.2 Digger derricks,if so equipped to position personnelor equipment,or both,may also be evaluated with this testmethod in conjunction with Test Method F914.1.1.2 Equipment Not CoveredExcluded from this testmethod are general-purpose cranes designed only for liftingservice and machines primarily designed only for diggingholes.1.2 The AE test method is used to detect and area-locateemission sources.Verification of emission sources may requirethe use of other nondestructive test(NDT)methods,such asradiography,ultrasonic,magnetic particle,liquid penetrant,andvisual inspection.1.3 WarningThis test method requires that external loadsbe applied to the superstructure of the vehicle under test.During the test,caution must be taken to safeguard personneland equipment against unexpected failure or instability of thevehicle or components.1.4 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.1.5 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:2E94 Guide for Radiographic Examination Using IndustrialRadiographic FilmE114 Practice for Ultrasonic Pulse-Echo Straight-BeamContact TestingE164 Practice for Contact Ultrasonic Testing of WeldmentsE569 Practice for Acoustic Emission Monitoring of Struc-tures During Controlled StimulationE610 Terminology Relating to Acoustic Emission(With-drawn 1991)3E650 Guide for Mounting Piezoelectric Acoustic EmissionSensorsE750 Practice for Characterizing Acoustic Emission Instru-mentationE976 Guide for Determining the Reproducibility ofAcousticEmission Sensor ResponseE1417/E1417M Practice for Liquid Penetrant TestingE1444/E1444M Practice for Magnetic Particle TestingF914 Test Method for Acoustic Emission for Insulated andNon-Insulated Aerial Personnel Devices Without Supple-mental Load Handling Attachments2.2 Other Standards:ASNT Recommended Practice SNT-TC-1A PersonnelQualification and Certification in Nondestructive Testing4ANSI A10.31 Digger DerricksSafety Requirements,Definitions,and Specifications51This test method is under the jurisdiction of ASTM Committee F18 onElectrical Protective Equipment for Workers and is the direct responsibility ofSubcommittee F18.55 on Inspection and Non-Destructive Test Methods for AerialDevices.Current edition approved March 1,2018.Published April 2018.Originallyapproved in 1997.Last previous edition approved in 2015 as F179715.DOI:10.1520/F1797-18.2For 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.4Available from American Society of Nondestructive Testing,4153 ArlingatePlaza,Caller#28518,Columbus,OH 43228.5Available from the American National Standards Institute,1430 Broadway,New York,NY 10018.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 EMI Nomenclature and Specifications for Truck-MountedExtensible Aerial Devices,Articulating Aerial Devices,Digger-Derricks63.Terminology3.1 Definitions:3.1.1 acoustic emission,AEthe class of phenomenawhereby elastic waves are generated by the rapid release ofenergy from a l
