Non-destructive testing - Equipment for eddy current examination - Array probe characteristics and verification (ISO 20339:2017)

ISO 20339:2017 identifies the functional characteristics of eddy current array probes and their interconnecting elements and provides methods for their measurement and verification.
The evaluation of these characteristics permits a well-defined description and comparability of eddy current array probes.
Where relevant, this document gives recommendations for acceptance criteria for the characteristics.

Zerstörungsfreie Prüfung - Technische Ausrüstung für die Wirbelstromprüfung - Kenngrößen von Sensorarrays und deren Verifizierung (ISO 20339:2017)

Dieses Dokument legt die Funktionskenngrößen von Wirbelstrom-Sensorarrays und zugehörigen Verbindungselementen fest und stellt Verfahren für deren Messung und Verifi¬zierung bereit.
Die Beurteilung dieser Kenngrößen ermöglicht eine genaue Beschreibung und die Vergleichbarkeit von Wirbelstrom-Sensorarrays.
Sofern relevant gibt dieses Dokument Empfehlungen für Annahmekriterien der Kenngrößen.

Essais non destructifs - Appareillage pour examen par courants de Foucault - Caractéristiques des capteurs multiéléments et vérifications (ISO 20339:2017)

ISO 20339:2017Foucault et de leurs éléments d'interconnexion, et fournit des méthodes pour les mesurer et les vérifier.
L'évaluation de ces caractéristiques permet de donner une description bien définie des capteurs multiéléments à courants de Foucault et d'assurer la possibilité de les comparer.
Le cas échéant, le présent document donne des recommandations relatives aux critères d'acceptation pour les caractéristiques.

Neporušitvene preiskave - Oprema za preiskave z vrtinčnimi tokovi - Značilnosti vrste sonde in preverjanje (ISO 20339:2017)

Namen tega standarda je določanje funkcijskih značilnosti sonde za vrtinčne tokove in njenih povezovalnih elementov ter navajanje metod za merjenje in preverjanje s temi instrumenti. Ocena teh značilnosti omogoča dobro opredeljen opis in primerjavo opreme za preiskave z vrtinčnimi tokovi. Sonde in njihovi povezovalni elementi so izbrani za izpolnjevanje zahtev predvidene uporabe. Na zasnovo vpliva oprema, s katero se uporabljajo. Ta standard podaja merila sprejemljivosti za značilnosti (v obliki priporočil).
