Non-destructive testing - Acoustic emission testing - Inservice acoustic emission monitoring of metallic pressure equipment and structures - General requirements

This document specifies general requirements for in-service acoustic emission (AE) monitoring. It relates to detection, location and grading of AE sources with application to metallic pressure equipment and other structures such as bridges, bridge ropes, cranes, storage tanks, pipelines, wind turbine towers, marine applications, offshore structures. The monitoring can be periodic, temporary or continuous, on site or remote-controlled, supervised or automated. The objectives of AE monitoring are to define regions which are acoustically active as a result of damage or defect evolution.

Zerstörungsfreie Prüfung - Schallemissionsprüfung - Überwachung der Schallemission von metallischen Druckgeräten und -strukturen im Betrieb - Allgemeine Grundsätze

Dieses Dokument legt allgemeine Anforderungen an die Überwachung der Schallemission (AE) während des Betriebs fest. Es bezieht sich auf die Erkennung, Ortung und Klassifizierung von AE-Quellen von metallischen Druckgeräten und andere Konstruktionen, wie Brücken, Brückenseile, Krane, Lagertanks, Rohrleitungen, Windenergiemaste, Schiffe und Offshore-Bauwerke. Die Überwachung kann periodisch, temporär oder kon¬tinuierlich, vor Ort oder ferngesteuert, beaufsichtigt oder automatisiert erfolgen. Das Ziel der AE-Überwachung ist, Bereiche zu bestimmen, die aufgrund von Schäden oder Fehlerentwicklungen akustisch aktiv sind.

Essais non destructifs - Contrôle par émission acoustique - Surveillance en service par émission acoustique des équipements et structures métalliques sous pression - Exigences générales

Le présent document spécifie les exigences générales relatives à la surveillance en service par émission acoustique (EA). Il porte sur la détection, la localisation et le classement des sources d’EA, avec une application aux équipements sous pression et autres structures métalliques tels que ponts, câbles de pont, grues, réservoirs de stockage, pipelines, mâts d’éoliennes, applications maritimes, structures offshore. La surveillance peut être périodique, temporaire ou continue, sur site ou à distance, supervisée ou automatisée. Les objectifs de la surveillance par EA sont de définir les zones qui sont acoustiquement actives à la suite de l’évolution d’un dommage ou d’un défaut.

Neporušitvene preiskave - Akustična emisija - Nadzorovanje akustične emisije pri uporabi kovinske tlačne opreme in drugih kovinskih struktur - Splošne zahteve

Ta standard opisuje nadzorovanje akustične emisije (AE) za ugotavljanje, iskanje in razvrščanje virov akustične emisije pri uporabi kovinske tlačne opreme in drugih kovinskih struktur. Nadzorovanje je lahko periodično, začasno ali stalno; izvaja se lahko na kraju samem ali na daljavo, pod nadzorom ali avtomatizirano. Cilj nadzorovanja akustične emisije je določitev območij, ki so akustično aktivna zaradi nastanka škode ali napak v razvoju.
