1.1 本标准涵盖了E07无损检测委员会编制的标准中使用的术语。这些无损检测（NDT）方法包括:声发射、电磁检测、伽马射线和X射线、泄漏检测、液体渗透检测、磁粉检测、中子放射学和测量、超声波检测以及其他技术方法。 1.2 E07委员会认识到，术语检查、测试和检验在无损检测中通常被用作同义词。为了确保E07无损检测标准的一致性和连贯性，E07委员会鼓励在描述无损检测方法的应用时使用术语检查或检验及其衍生词。在特定标准中，应在整个文件中一致使用检查或检验。同样，E07鼓励在提及无损检测方法的知识体系时使用术语测试及其衍生词。 然而，当术语测试及其衍生物可用于描述无损检测的应用时，也有适当的例外情况，例如产生数值结果的测量（例如，当使用泄漏检测方法对组件进行泄漏检测或超声波速度测量时）。此外，当提及无损检测方法时，应使用术语测试，即放射性检测（RT）、超声波检测（UT）等。（示例:放射检测（RT）通常用于检查材料以检测内部不连续性。） 注1: 以下句子澄清了这一政策并说明了其用途: 一 无损检测方法广泛用于材料和部件的检查或检验。 b E07无损检测委员会编制了许多文件，以促进统一使用用于检查或检验材料和部件的无损检测方法。 c 放射检测（RT）通常用于检查材料以检测内部不连续性。 d 磁粉检测（MT）、液体渗透检测（PT）和目视检测（VT）通常用于检查部件的表面。 e 气泡泄漏测试（BLT）方法有时用于对承压部件进行泄漏测试，以检测泄漏。 f 增材制造材料无损检测指南将描述几种方法，但实践将侧重于一种检测方法。 1.3 A节定义了多种无损检测方法共有的术语，而后续章节定义了与特定无损检测方法相关的术语。 1.4 如下图所示，当无损检测或检验产生指示时，该指示可能被解释为错误、无关或相关。如果被解释为相关，则必要的后续评估将导致决定接受或拒绝该材料。 除了接受和拒绝，它们保留了大多数词典中的含义，图表中使用的所有单词都在A节中定义。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 =====意义和用途====== 3.1 本标准中的术语旨在在所有无损检测标准中统一一致地使用。本标准的目的是促进对使用无损检测标准的清晰理解和解释。

1.1 This standard covers 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 use of the terms examination or inspection and their derivatives when describing the application of nondestructive test methods. In a specific standard, either examination or inspection shall be used consistently throughout the document. Similarly, E07 encourages the use of the term test and its derivatives when referring to the body of knowledge of a nondestructive testing method. 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.) Note 1: The following sentences clarify this policy and illustrate its use: (a) Nondestructive testing methods are used extensively for the examination or inspection of materials and components. (b) The E07 Committee on Nondestructive Testing has prepared many documents to promote uniform usage of the nondestructive testing methods that are applied to examine or inspect materials and components. (c) Radiologic Testing (RT) is often used to inspect material to detect internal discontinuities. (d) Magnetic Particle Testing (MT), Liquid Penetrant Testing (PT), and Visual Testing (VT) are often used to examine the surface of a component. (e) The Bubble Leak Testing (BLT) method is sometimes used to leak test a pressure containing component to detect leaks. (f) A guide for Nondestructive Testing of additively manufactured materials will describe several methods but a practice will focus on a single inspection method. 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 a nondestructive examination or inspection 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. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 3.1 The terms found in this standard are intended to be used uniformly and consistently in all nondestructive testing standards. The purpose of this standard is to promote a clear understanding and interpretation of the NDT standards in which they are used.
