Designation: E1316 − 17aStandard Terminology forNondestructive Examinations 1This standard is issued under the f i xed 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 def i nes 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 def i nes terms that are common to multipleNDT methods, whereas, the subsequent sections def i ne termspertaining to specif i c 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 aredef i ned in Section A.1 This terminology is under the jurisdiction of Committee E07 on NondestructiveTesting and is the direct responsibility of Subcommittee E07.92 on EditorialReview.Current edition approved June 15, 2017.
