Non-destructive testing - Terminology - Part 9: Terms used in acoustic emission testing

This European Standard is concerned only with terms used specifically in acoustic emission testing (AT) and these fall into four parts:
-   terms relating to the physical phenomenon;
-   terms relating to the detection of the acoustic emission;
-   terms relating to the measured characteristics of the signal(s);
-   terms relating to acoustic emission applications.

Zerstörungsfreie Prüfung - Terminologie - Teil 9: Begriffe der Schallemissionsprüfung

Diese Europäische Norm betrifft nur Begriffe, die speziell auf dem Gebiet der Schallemissionsprüfung (en: acoustic emission testing, AT) verwendet werden, und diese sind in vier Gruppen eingeteilt:
-   Begriffe in Bezug auf das physikalische Phänomen;
-   Begriffe in Bezug auf den Nachweis von Schallemission;
-   Begriffe, die sich auf die gemessenen Merkmale des (der) Signals (Signale) beziehen;
-   Begriffe in Bezug auf die Anwendungen der Schallemission.

Essais Non Destructifs - Terminologie - Partie 9 : Termes utilisés en contrôle par émission acoustique

La présente Norme européenne définit uniquement les termes spécifiques du contrôle par émission acoustique (AT), lesquels sont répartis en quatre catégories :
-   les termes relatifs au phénomène physique ;
-   les termes relatifs à la détection de l'émission acoustique ;
-   les termes relatifs aux caractéristiques mesurées des signaux ;
-   les termes relatifs aux applications de l’émission acoustique.

Neporušitvene preiskave - Terminologija - 9. del: Izrazi, ki se uporabljajo pri akustični emisiji

Ta evropski standard se nanaša le na izraze, ki se uporabljajo posebej za preizkušanje akustične emisije (AT) in se delijo na štiri dele:
– izrazi, ki se nanašajo na fizikalni pojav;
– izrazi, ki se nanašajo na odkrivanje akustičnih emisij;
– izrazi, ki se nanašajo na izmerjene značilnosti signala(-ov);
– izrazi, ki se nanašajo na uporabo akustičnih emisij.
