Designation:E131615Standard Terminology forNondestructive Examinations1This standard is issued under the fixed designation E1316;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.INDEX OF TERMSSectionA:Common NDT TermsB:Acoustic Emission(AE)TermsC:Electromagnetic Testing(ET)TermsD:Gamma-and X-Radiologic Testing(RT)TermsE:Leak Testing(LT)TermsF:Liquid Penetrant Testing(PT)TermsG:Magnetic Particle Testing(MT)TermsH:Neutron Radiologic Testing(NRT)TermsI:Ultrasonic Testing(UT)TermsJ:Infrared Testing(IRT)TermsK:Holographic Testing(HT)TermsL:Visual Testing(VT)Terms1.Scope1.1 This standard defines the terminology used in thestandards prepared by the E07 Committee on NondestructiveTesting.These nondestructive testing(NDT)methods include:acoustic emission,electromagnetic testing,gamma-andX-radiology,leak testing,liquid penetrant testing,magneticparticle testing,neutron radiology and gauging,ultrasonictesting,and other technical methods.1.2 Committee E07 recognizes that the terms examination,testing and inspection are commonly used as synonyms innondestructive testing.For uniformity and consistency in E07nondestructive testing standards,Committee E07 encouragesthe use of the term examination and its derivatives whendescribing the application of nondestructive test methods.There are,however,appropriate exceptions when the term testand its derivatives may be used to describe the application ofa nondestructive test,such as measurements which produce anumeric result(for example,when using the leak testingmethod to perform a leak test on a component,or an ultrasonicmeasurement of velocity).Additionally,the term test should beused when referring to the NDT method,that is,RadiologicTesting(RT),Ultrasonic Testing(UT),and so forth.(Example:Radiologic Testing(RT)is often used to examine material todetect internal discontinuities.)1.3 Section A defines terms that are common to multipleNDT methods,whereas,the subsequent sections define termspertaining to specific NDT methods.1.4 As shown on the chart below,when nondestructivetesting produces an indication,the indication is subject tointerpretation as false,nonrelevant or relevant.If it has beeninterpreted as relevant,the necessary subsequent evaluationwill result in the decision to accept or reject the material.Withthe exception of accept and reject,which retain the meaningfound in most dictionaries,all the words used in the chart aredefined in Section A.1This terminology is under the jurisdiction of Committee E07 on NondestructiveTesting and is the direct responsibility of Subcommittee E07.92 on EditorialReview.Current edition approved Sept.1,2015.Published October 2015.Originallyapproved in 1989.Last previous edition approved in 2014 as E1316 141.DOI:10.1520/E1316-15.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 2.Referenced Documents2.1 ASTM Standards:2NOTE1This standard defines the terminology used in the standardsprepared by Committee E07 on Nondestructive Testing and published inthe Annual Book of ASTM Standards,Volume 03.03.3.Significance and Use3.1 The terms found in this standard are intended to be useduniformly and consistently in all nondestructive testing stan-dards.The purpose of this standard is to promote a clearunderstanding and interpretation of the NDT standards inwhich they are used.4.TerminologySection A:Common NDT TermsThe terms defined in Section A are the direct responsibility of Subcommittee E07.92,Editorial Review.acceptable quality levelthe maximum percent defective orthe maximum number of units defective per hundred unitsthat,for the purpose of sampling test,can be consideredsatisfactory as a process average.calibration,instrument,nthe comparison of an instrumentwith,or the adjustment of an instrument to,a knownreference(s)often traceable to the National Institute ofStandardsandTechnology(NIST).(Seealsostandardization,instrument.)cognizant engineering organizationthe company,govern-ment agency or other authority responsible for the design,orend use,of the material or component for which nondestruc-tive testing is required.DISCUSSIONIn addition to design personnel,the cognizant engineer-ing organization could include personnel from engineering,materialand process engineering,stress analysis,nondestructive testing,qualityassurance and others,as appropriate.defect,none or more flaws whose aggregate size,shape,orientation,location,or properties do not meet specifiedacceptance criteria and are rejectable.discontinuity,na lack of continuity or cohesion;an inten-tional or unintentional interruption in the physical structureor configuration of a material or component.evaluationdetermination of whether a relevant indication iscause to accept or to reject a mat
