Non-destructive testing - Acoustic emission testing - Examination of metallic pressure equipment during proof testing - Planar location of AE sources
This European Standard describes the method for conducting acoustic emission testing (AT) of metallic pressure equipment during acceptance pressure testing using a planar location method. This standard is applicable also for subsequent tests for requalification. General principles of Acoustic Emissions are described in EN 13554.
The objectives of the AE testing are to provide 100 % volumetric testing to define regions of the structure which are acoustically active with burst type AE, e.g. as a result of evolution of sub-critical discontinuities, thus increasing the reliability of the acceptance test. The test provides a reference map for comparison with results of future tests.
Zerstörungsfreie Prüfung - Schallemissionsprüfung - Prüfung von metallischen Druckgeräten während der Abnahmeprüfung - Planare Ortung von Schallemissionsquellen
Diese Europäische Norm legt das Verfahren zur Durchführung einer Schallemissions-prüfung (AT; en: Acoustic Emission Testing) an metallischen Druckgeräten während der Druck-Abnahmeprüfung unter Anwendung der planaren Ortung fest. Diese Norm ist auch für nachfolgende Prüfungen zur Requalifizierung anwendbar. Allgemeine Grundlagen der Schallemission sind in EN 13554 beschrieben.
Das Ziel der Schallemissionsprüfung ist eine 100 % Volumenprüfung, um jene Regionen im Bauteil zu bestimmen, die, akustisch aktiv, Schallemissionen vom Burst-Typ erzeugen, z. B. als Folge des Wachstums von subkritischen Inhomogenitäten, was die Zuverlässigkeit der Abnahmeprüfung erhöht. Die Prüfung liefert Referenzdaten für den Vergleich mit den Ergebnissen späterer Prüfungen.
Essais non destructifs - Essais d'émission acoustique - Contrôle des équipements métalliques sous pression pendant l'épreuve - Localisation planaire des sources d'EA
La présente Norme européenne décrit la méthode à utiliser pour effectuer le contrôle de l'émission acoustique (AT) des équipements métalliques sous pression pendant l’épreuve en pression réalisée lors de leur réception, à l’aide de la méthode de localisation par planaire. Cette norme est également applicable pour les essais ultérieurs de requalification. Les principes généraux d'émission acoustique sont décrits dans l’EN 13554.
Le contrôle par EA a pour objectif d'assurer un contrôle volumétrique à 100 % en vue de définir les zones acoustiquement actives de la structure grâce à la détection des salves d'émission acoustique, c'est-à-dire celles qui résultent de l'évolution des discontinuités sous-critiques. Il permet, ce faisant, d'améliorer la fiabilité de l'essai de réception. L'essai fournit une cartographie de référence permettant la comparaison avec les résultats de contrôles futurs.
Neporušitveno preskušanje - Akustična emisija - Pregled kovinskih tlačnih naprav med preskušanjem
Ta evropski standard opisuje metodo za izvajanje preskušanja akustičnih emisij (AT) kovinskih tlačnih naprav med preskušanjem sprejemljivosti z uporabo metode ravninske namestitve. Ta standard se uporablja tudi za poznejše preskuse za prekvalifikacijo. Splošna načela akustičnih emisij so opisana v standardu EN 13554. Cilji preskušanja akustičnih emisij so zagotoviti 100-odstotno volumetrično preskušanje za opredelitev predelov strukture, ki so akustično dejavni z nestalnimi akustičnimi emisijami, npr. kot posledica razvoja nekritičnih nepravilnosti, pri čemer se poveča zanesljivost preskusa sprejemljivosti. Preskus zagotavlja referenčno karto za primerjavo z rezultati prihodnjih preskusov.

To demonstrate appropriate qualification, it is recommended that personnel be certified according to EN ISO 9712 or an equivalent formalised system. Operating authorisation for a qualified person shall be issued by the employer in accordance with a written procedure. NDT operations, unless otherwise agreed, shall be authorised by a competent and qualified NDT supervisory individual (Level 3 according to EN ISO 9712 or equivalent) approved by the employer.

Dependent upon the results of the initial loading, a reduction of the load to working pressure or lower, followed by re-pressurisation, may be required. 5.3 Sensors The most commonly used frequency range is 100 kHz to 300 kHz. Lower frequency monitoring allows detection at greater distances and higher frequency monitoring provides improved rejection of external noise. Selection of frequency range may optimise location accuracy by avoiding the detection of multiple wave modes. The equipment surface below the sensors shall be cleaned to ensure the maximum coupling efficiency. The sensor coupling shall be as specified in the written test instruction. The sensors may be directly attached to the structure using magnetic devices or an adhesive.
The effectiveness and reliability of the acoustic coupling shall be verified. The characteristics of the type of the acoustic coupling used shall not affect the structure adversely. 5.4 Location The location of AE sources is performed using ∆t measurement. The accuracy is normally within ± 5 % of the maximum used sensor spacing (dmax,u) (see 7.1.2) and shall be measured and verified using an artificial source. The artificial source shall have an amplitude equivalent to the Hsu-Nielsen source minus the value of K. Alternatively a Hsu-Nielsen source may be used and the detection SIST EN 14584:2013
For difficult geometry, e.g. nozzles, manholes, reference measurements shall be made.
