EN 1330-9:2017 (E) 3 European foreword This document (EN 1330-9:2017) has been prepared by Technical Committee CEN/TC 138 “Non-destructive testing”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2018, and conflicting national standards shall be withdrawn at the latest by January 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1330-9:2009.

EN 1330-9:2017 (E) 4 1 Scope This European Standard is concerned only with terms used specifically in acoustic emission testing (AT) and these fall into four parts: a) terms relating to the physical phenomenon; b) terms relating to the detection of the acoustic emission; c) terms relating to the measured characteristics of the signal(s); d) terms relating to acoustic emission applications. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 General 2.1.1 acoustic emission AE phenomena whereby transient elastic waves are generated by, e.g. plastic deformation, crack propagation, erosion, corrosion, impact, leakage 2.2 Terms relating to the physical phenomenon 2.2.1 acoustic emission event physical phenomenon giving rise to acoustic emission 2.2.2 acoustic emission source spatial element from where one (or more) acoustic emission event(s) originate(s) 2.2.3 acoustic emission event mechanism dynamic process or combination of processes occurring within a material, generating acoustic emission events Note 1 to entry: AE event mechanisms can be subdivided into several categories: material and mechanical, macroscopic and microscopic, primary and secondary. 2.2.4 acoustic emission wave transient elastic wave generated by an acoustic emission event 2.2.5 acoustic emission wave energy elastic wave energy released by an acoustic emission event 2.2.6 acoustic emission stimulation application of a stimulus such as force, pressure, heat, and so forth, to a test object to cause activation of acoustic emission sources SIST EN 1330-9:2017
