Non-destructive testing - Ultrasonic testing - Sensitivity and range setting (ISO 16811:2025)

This document specifies the general rules for setting the time-base range and sensitivity (i.e. gain adjustment) of a manually operated ultrasonic instrument with A-scan display in order that reproducible determinations can be made of the location and echo height of a reflector.
This document is applicable to contact techniques employing a single probe with either a single transducer or dual transducers. This document does not apply to the immersion technique and techniques employing more than one probe.

Zerstörungsfreie Prüfung - Ultraschallprüfung - Empfindlichkeits- und Entfernungsjustierung (ISO 16811:2025)

Dieses Dokument legt die allgemeinen Regeln für die Einstellung des Justierbereichs und der Empfindlichkeit (d. h. die Verstärkungseinstellung) eines manuell betriebenen Ultraschallgeräts mit A-Bild-Darstellung fest, um die Lage und Echohöhe eines Reflektors reproduzierbar bestimmen zu können.
Dieses Dokument ist bei Kontakttechniken anwendbar, bei denen ein einzelner Prüfkopf verwendet wird, der entweder ein Einschwinger-Prüfkopf oder ein Prüfkopf mit zwei getrennten Wandlern (SE-Prüfkopf) ist. Dieses Dokument ist nicht anwendbar bei der Tauchtechnik und Techniken mit mehr als einem Prüfkopf.

Essais non destructifs - Contrôle par ultrasons - Réglage de la sensibilité et de la base de temps (ISO 16811:2025)

Le présent document spécifie les règles générales de réglage de l’échelle de la base de temps et de la sensibilité (c’est-à-dire la commande de gain) d’un appareil de contrôle par ultrasons à commande manuelle et à représentation de type A afin de pouvoir effectuer des déterminations reproductibles de la localisation et de la hauteur d’écho d’un réflecteur.
Le présent document s’applique aux techniques au contact qui utilisent un traducteur à transducteur simple ou à émetteur et récepteur séparés. Le présent document ne s’applique pas à la technique en immersion ni aux techniques utilisant plus d’un traducteur.
