(Main)Non-destructive testing - Characterization and verification of ultrasonic examination equipment - Part 1: Instruments
Non-destructive testing - Characterization and verification of ultrasonic examination equipment - Part 1: Instruments
This European Standard specifies methods and acceptance criteria for assessing the electrical performance of analogue and digital ultrasonic instruments for pulse operation using A scan display, employed for manual ultrasonic non-destructive examination with single or dual-element probes operating within the centre frequency range 0,5 MHz to 15 MHz. Ultrasonic instruments for continuous waves are not included in this standard. This standard may partly be applicable to ultrasonic instruments in automated systems but then other tests can be needed to ensure satisfactory performance.
Zerstörungsfreie Prüfung - Charakterisierung und Verifizierung der Ultraschall-Prüfausrüstung - Teil 1: Prüfgeräte
Dieses Dokument legt Verfahren und Zulässigkeitskriterien fest, mit denen die elektrischen Eigenschaften von
analogen und digitalen Ultraschall-Prüfgeräten für Impulsbetrieb, mit A-Bild-Darstellung, vorgesehen für die
manuelle, zerstörungsfreie Ultraschallprüfung mit Einzelschwinger-Prüfköpfen und SE-Prüfköpfen, für den
Mittenfrequenzbereich von 0,5 MHz bis 15 MHz, bewertet werden sollen. Ultraschall-Prüfgeräte für Dauerschall
sind von dieser Norm nicht betroffen. Teile dieser Norm dürfen für Ultraschall-Prüfgeräte in automatisierten
Prüfanlagen herangezogen werden, was dann jedoch zusätzliche Prüfungen erforderlich macht, um
zufriedenstellende Leistungen sicherzustellen.
Essais non destructifs - Caractérisation et vérification de l'appareillage de contrôle par ultrasons - Partie 1 : Appareils
La présente Norme européenne spécifie les modes opératoires et les critères d’acceptation permettant
d’évaluer les performances électriques des appareils de contrôle par ultrasons à modes impulsionnel,
analogique et numérique, utilisant une représentation de type A, employés pour le contrôle non destructif par
ultrasons en manuel, avec traducteurs simples ou à émetteur et récepteur séparés fonctionnant dans la
gamme de fréquences centrales comprises entre 0,5 MHz et 15 MHz. Les appareils de contrôle par ultrasons
à ondes entretenues ne sont pas inclus dans la présente norme. Certaines parties de la présente norme
peuvent s’appliquer aux appareils de contrôle par ultrasons utilisés dans des systèmes automatisés, mais,
dans ce cas, des essais supplémentaires peuvent être nécessaires pour garantir des performances
satisfaisantes.
Neporušitveno preskušanje - Ugotavljanje značilnosti in overjanje naprav za ultrazvočno preskušanje - 1. del: Aparati
Ta evropski standard določa metode in merila sprejemljivosti za ugotavljanje električne zmogljivosti analognih in digitalnih ultrazvočnih instrumentov za pulzno delovanje z uporabo prikazovalnika za A-skeniranje, ki se uporabljajo za ročno ultrazvočno neporušitveno preiskavo s sondami z enojnim ali dvojnim elementom, ki delujejo v okviru osrednjega frekvenčnega razpona od 0,5 MHz do 15 MHz. Ultrazvočni instrumenti za neprekinjene valove niso vključeni v ta standard. Ta standard se lahko deloma uporablja za ultrazvočne instrumente v avtomatskih sistemih, vendar so lahko potrebni drugi preskusi, da se zagotovi zadovoljivo delovanje.
