Non-destructive testing - Characterization and verification of ultrasonic examination equipment - Part 3: Combined equipment

This European Standard describes methods and acceptance criteria for verifying the performance of ultrasonic equipment (i.e. instrument and probe combined as defined in EN 12668-1 and EN 12668-2) by the use of appropriate standard calibration blocks. These methods are not intended to prove the suitability of the equipment for particular applications. The methods described are suitable for the use by operators working under site or shop floor conditions. The methods only apply to pulse echo equipment using A-scan presentation, with gain controls or attenuators calibrated in steps not greater than 2 dB and used essentially in contact testing. These methods are specifically intended for manual testing equipment. For automated testing different tests can be needed to ensure satisfactory performance.

Zerstörungsfreie Prüfung - Charakterisierung und Verfizierung der Ultraschall-Prüfausrüstung - Teil 3: Komplette Prüfausrüstung

Diese Europäische Norm legt Verfahren und Zulässigkeitskriterien fest, mit denen die Leistungsfähigkeit der Ultraschall Prüfausrüstung (d. h. mit zusammengeschaltetem Prüfgerät und Prüfkopf nach EN 12668 1 und EN 12668 2) durch die Anwendung geeigneter, genormter Kalibrierkörper nachgewiesen werden. Diese Verfahren sind nicht dazu gedacht, die Eignung der Prüfausrüstung für bestimmte Anwendungen nachzuweisen. Die beschriebenen Verfahren können vom Prüfer selber unter den Bedingungen des Prüfortes durchgeführt werden. Diese Verfahren gelten nur für Impulsecho Prüfgeräte mit A Bild Darstellung, mit Verstärkungsreglern oder Abschwächern, die in Stufen nicht größer als 2 dB kalibriert sind und die hauptsächlich für die Prüfung im direkten Kontakt angewendet werden. Diese Verfahren sind insbesondere für die Prüfausrüstung zur manuellen Prüfung vorgesehen. Für die automatisierte Prüfung können andere Verfahren erforderlich sein, um das zufriedenstellende Leistungsvermögen zu bestätigen.

Essais non destructifs - Caractérisation et vérification de l'appareillage de contrôle par ultrasons - Partie 3: Equipement complet

Le présent document décrit les méthodes et les critères d'acceptation permettant de vérifier la performance d'un appareillage ultrasonore (c’est-à-dire : l'appareil combiné au traducteur comme défini dans l’EN 12668-1 et l’EN 12668-2) à l'aide de blocs d'étalonnage normalisés appropriés. Ces méthodes ne visent pas à établir l'aptitude à l'emploi de l'appareillage pour des applications particulières. Les méthodes décrites sont celles à utiliser par des opérateurs travaillant sur site ou en atelier. Elles ne s'appliquent qu'aux seuls instruments de contrôle par réflexion avec représentation de type A, commandes de gains ou dispositifs d'atténuation étalonnés par 2 dB maximum et qui sont essentiellement utilisés pour le contrôle par contact. Ces méthodes sont conçues spécifiquement pour l'appareillage utilisé pour le contrôle manuel. Pour le contrôle automatique, des essais différents peuvent être nécessaires pour garantir une performance satisfaisante.

Neporušitvene preiskave - Karakterizacija in preverjanje naprav za ultrazvočne preiskave - 3. del: Sestavljeni sistemi

Ta evropski standard opisuje metode in kriterije sprejemljivosti za preverjanje delovanja ultrazvočne opreme (tj. instrument in sonda v eni napravi, kot določata standarda EN 12668-1 in EN 12668-2) z uporabo primernih standardnih ploščic za umerjanje. Te metode niso namenjene dokazovanju primernosti opreme za posebne uporabe. Opisane metode so primerne za izvajalce, ki delajo v razmerah na terenu ali na delovnem mestu. Metode veljajo le za opremo s pulzno-odbojnim delovanjem z A-scan prikazom s krmilniki ojačanja ali atenuatorji, kalibriranimi na stopnje, ki niso večje od 2 dB, in se uporabljajo predvsem v kontaktnih preizkusih. Te metode so namenjene zlasti ročnemu preskušanju opreme. Za avtomatsko preskušanje so morda potrebni drugačni preizkusi, da se zagotovi zadovoljivo delovanje.

The linearity shall be checked over a range at least equal to that which is to be used in subsequent testing. Where appropriate, due allowance can be made for the fact that a range of 91 mm for compressional waves in steel is equivalent to a range of only 50 mm for shear waves. 3.2.1.2 Procedure Place the probe on the calibration block in a position where the range to the last backwall or radius echo is equal to or exceeds the range over which the linearity shall be checked. Adjust the timebase so that the first and the sixth backwall echoes coincide with the first and last scale marks respectively. Check the linearity with the four other echoes. Bring the backwall echoes, in turn, to approximately the same height e.g. 80 % full screen height. The leading edge of each echo should line up with the appropriate graticule line. Check that any deviations from the ideal positions are within the specified tolerance when measured at the same screen height when the first and the sixth echo were positioned. 3.2.1.3 Tolerance The deviation from linearity shall not exceed ± 2 % of full screen width. 3.2.1.4 Frequency of checking The check shall be carried out at least once per week for ultrasonic instruments to be used during that week.

Any standard calibration block can be used for this test, preferably in conjunction with the probe that will be used in subsequent testing. The linearity shall be checked with the ultrasonic instrument controls (frequency, range, pulse energy, etc.) switched to positions to be employed in subsequent testing.
