Designation:F914/F914M15Standard Test Method forAcoustic Emission for Aerial Personnel Devices WithoutSupplemental Load Handling Attachments1This standard is issued under the fixed designation F914/F914M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method describes a procedure for non-destructive testing using acoustic emission(AE)testing foraerial personnel devices,which do not have a supplementalload handling attachment.1.1.1 Equipment CoveredThis test method covers thefollowing types of vehicle-mounted insulated aerial personneldevices:1.1.1.1 Extensible boom aerial personnel devices,1.1.1.2 Articulating boom aerial personnel devices,and1.1.1.3 Any combination of 1.1.1.1 and 1.1.1.2.1.1.2 Equipment Not CoveredThis test method does notcover any of the following equipment:1.1.2.1 Material-handling aerial devices,1.1.2.2 Digger-derricks with platform,and1.1.2.3 Cranes with platform.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,ultrasonics,magnetic particle,liquid penetrant,and visual inspection.WarningThis test method requiresthat external loads be applied to the superstructure of thevehicle under test.During the test,caution must be taken tosafeguard personnel and equipment against unexpected failureor instability of the vehicle or components.NOTE1This test method is not intended to be a stand alone NDTmethod for the verification of the structural integrity of an aerial device.Other NDT methods should be used to supplement the results.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2E94 Guide for Radiographic ExaminationE114 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 TestingF2174 Practice for Verifying Acoustic Emission Sensor Re-sponse2.2 ANSI Standard:ANSI A92.2 Standard for Vehicle-Mounted Elevating andRotating Aerial Devices42.3 ASNT Standard:ASNT Recommended Practice SNT-TC-1A53.Terminology3.1 Definitions:1This 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 April 1,2015.Published May 2015.Originallyapproved in 1985.Last previous edition approved in 2014 as F914/F914M 14.DOI:10.1520/F0914_F0914M-15.2For 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.3Withdrawn.The last approved version of this historical standard is referencedon www.astm.org.4Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.5Available fromAmerican Society for Nondestructive Testing(ASNT),P.O.Box28518,1711 Arlingate Ln.,Columbus,OH 43228-0518,http:/www.asnt.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.1.1 acoustic emission(AE)the class of phenomenawhereby elastic waves are generated by the rapid release ofenergy from a localized source or sources within a material,orthe transient elastic wave(s)so generated.Acoustic emission isthe recommended term for general use.Other terms that havebeen used in AE literature include stress wave emission,microseismic activity,and emission or acoustic emission withother qualifying modifiers.3.1.2 aerial personnel deviceany device extensible,articulating,or both,that is designed to posit
