1. Scope
1.1 This standard defines the terminology used in the standards prepared by the E07 Committee on Nondestructive Testing. These nondestructive testing (NDT) methods include: acoustic emission， electromagnetic testing， gamma- and X-radiology, leak testing, liquid penetrant testing, magnetic particle testing, neutron radiology and gauging， ultrasonic testing, and other technical methods. 1.2 Committee E07 recognizes that the terms examination, testing, and inspection are commonly used as synonyms in nondestructive testing. For uniformity and consistency in E07 nondestructive testing standards, Committee E07 encourages the usc of the term examination and its derivatives when describing the application of nondestructive test methods. There are, however, appropriate exceptions when the term test and its derivatives may be used to describe the application of a nondestructive test, such as measurements which produce a numeric result (for example, when using the leak testing method to perform a leak test on a component, or an ultrasonic measurement of velocity). Additionally, the term test should be used when referring to the NDT method, that is, Radiologic Testing (RT), Ultrasonic Testing (UT), and so forth. (Example:Radiologic Testing (RT) is often used to examine material to detect internal discontinuities.) 1.3 Section A defines terms that are common to multiple NDT methods, whereas the subsequent sections define terms pertaining to specific NDT methods. 1.4 As shown on the chart below, when nondestructive testing produces an indication, the indication is subject to interpretation as false, nonrelevant, or relevant. If it has been interpreted as relevant, the necessary subsequent evaluation will result in the decision to accept or reject the material. With the exception of accept and reject, which retain the meaning found in most dictionaries, all the words used in the chart are defined in Section A.
acceptable quality level-the maximum percent defective or the maximum number of units defective per hundred units that, for the purpose of sampling test, can be considered satisfactory as a process average. calibration, instrument, n- -the comparison of an instrument with，or the adjustment of an instrument to，a known reference(s) often traceable to the National Institute of Standards and Technology (NIST). (See also standardization, instrument.) cognizant engineering organization- -the company, govern- ment agency or other authority responsible for the design, or end use, of the material or component for which nondestruc- live lesting is required, DISCUSsION- -In addition to design personnel, the cognizant engineer- ing organization could include personnel from engineering, material and process engineering, stress analysis, nondestructive testing, quality assurance and others, as appropriate. defect, n- one or more flaws whose aggregate size, shape, orientation，location, or properties do not meet specified acceptance criteria and are rejectable. Digital Imaging and Communication for Nondestructive Evaluation (DICONDE)-a vendor- neutral digital data storage and transmission protocol that defines the organiza- tion of NDT image data and associated metadata in a standard electronic format. DIsCUSsIoN- -DICONDE is based on and inherits from the univer- sally adopted medical standard, DICOM, which facilitates the interop- erability of imaging equipment through data storage and network communication protocols, discontinuity, n- a lack of continuity or cohesion; an inten- tional or unintentional interruption in the physical structure or configuration of a material or component.Nondestructive Testing (NDT), n- -the development and ap- plication of technical methods to examine materials or components in ways that do not impair future usefulness and serviceability in order to detect, locate, measure and evaluate flaws; to assess integrity, properties and composition; and to measure geometrical characteristics. nonrelevant indication, n- -an NDT indication that is caused by a condition or type of discontinuity that is not rejectable. False indications are non-relevant. reference standard, n- -a material or object for which all relevant chemical and physical characteristics are known and measurable, used as a comparison for, or standardization of, equipment or instruments used for nondestructive testing. (See also standardization, instrument.) relevant indication, n- -an NDT indication that is caused by a condition or type of discontinuity that requires evaluation.
