Designation:E100116Standard Practice forDetection and Evaluation of Discontinuities by theImmersed Pulse-Echo Ultrasonic Method Using LongitudinalWaves1This standard is issued under the fixed designation E1001;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This practice describes procedures for the ultrasonicexamination of bulk materials or parts by transmitting pulsed,longitudinal waves through a liquid couplant into the materialand observing the indications of reflected waves(see Fig.1).Itcovers only examinations in which one search unit is used asboth transmitter and receiver(pulse-echo)and in which the partor material being examined is coupled to the part by a liquidcolumn or is totally submerged in the couplant(either methodis considered to be immersion testing).This practice includesgeneral requirements and procedures which may be used fordetecting discontinuities and for making a relative or approxi-mate evaluation of the size of discontinuities.1.2 This practice replaces Practice E214 and provides moredetailed procedures for the selection,standardization,andoperation of an examination system and for evaluation of theindications obtained.1.3 UnitsThe values stated in inch-pound units are to beregarded as standard.The values given in parentheses aremathematical conversions to SI units that are provided forinformation only and are not considered 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:2C1212 Practice for Fabricating Ceramic Reference Speci-mens Containing Seeded VoidsC1336 Practice for Fabricating Non-Oxide Ceramic Refer-ence Specimens Containing Seeded InclusionsE127 Practice for Fabrication and Control of AluminumAlloy Ultrasonic Standard Reference BlocksE317 Practice for Evaluating Performance Characteristics ofUltrasonic Pulse-Echo Testing Instruments and Systemswithout the Use of Electronic Measurement InstrumentsE428 Practice for Fabrication and Control of Metal,Otherthan Aluminum,Reference Blocks Used in UltrasonicTestingE543 Specification for Agencies Performing NondestructiveTestingE1158 Guide for Material Selection and Fabrication ofReference Blocks for the Pulsed Longitudinal Wave Ul-trasonic Testing of Metal and Metal Alloy ProductionMaterialE1316 Terminology for Nondestructive Examinations2.2 ASNT Documents:3SNT-TC-1A Recommended Practice for Personnel Qualifi-cation and Certification in Nondestructive TestingANSI/ASNT-CP-189 for Qualification and Certification ofNondestructive Testing Personnel2.3 Aerospace Industries Association Document:4NAS-410 Certification and Qualification of NondestructiveTesting PersonnelNOTE1For DoD contracts,unless otherwise specified the issues of thedocuments,which are DoD adopted,are those listed in the issue of theDoDISS(Department of Defense Index of Specifications Standards)citedin the solicitation.1This practice is under the jurisdiction of ASTM Committee E07 on Nonde-structive Testing and is the direct responsibility of Subcommittee E07.06 onUltrasonic Method.Current edition approved Dec.1,2016.Published December 2016.Originallyapproved in 1984.Last previous edition approved in 2011 as E1001-11.DOI:10.1520/E1001-16.2For 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.3Available fromAmerican Society for Nondestructive Testing(ASNT),P.O.Box28518,1711 Arlingate Ln.,Columbus,OH 43228-0518,http:/www.asnt.org.4Available from Aerospace Industries Association of America,Inc.(AIA),1000Wilson Blvd.,Suite 1700,Arlington,VA22209-3928,http:/www.aia-aerospace.org.*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 Organiziation Technical Barriers to Trade(TBT)Committee.1 2.4 ISO Documents5ISO 9712 Non-destructive TestingQualification and Cer-tification for NDT Personnel3.Terminology3.1 DefinitionsFor definitions of terms used in thispractice,see Terminology E1316.3.2 Definitions of Terms Specifi
