Non-destructive testing - Ultrasonic thickness measurement (ISO 16809:2017)

ISO 16809:2017 specifies the principles for ultrasonic thickness measurement of metallic and non-metallic materials by direct contact, based on measurement of time of flight of ultrasonic pulses only.

Zerstörungsfreie Prüfung - Dickenmessung mit Ultraschall (ISO 16809:2017)

Dieses Dokument legt die Grundlagen für die Messung der Dicke metallischer und nicht metallischer Werkstoffe mit Ultraschall durch unmittelbaren Kontakt mit dem Prüfgegenstand fest, ausschließlich basierend auf der Messung der Laufzeit von Ultraschallimpulsen.

Essais non destructifs - Mesurage de l'épaisseur par ultrasons (ISO 16809:2017)

Le présent document spécifie les principes pour le mesurage de l'épaisseur par ultrasons de matériaux métalliques et non métalliques par contact direct, exclusivement basés sur la mesure du temps de vol d'impulsions ultrasonores.

Neporušitvene preiskave - Ultrazvočno merjenje debeline (ISO 16809:2017)

Standard ISO 16809:2017 določa načela za ultrazvočno merjenje debeline kovinskih in nekovinskih materialov z neposrednim stikom, in sicer samo na podlagi merjenja časa preleta ultrazvočnih impulzov.
