Non-destructive testing - Equipment for eddy current examination - Part 1: Instrument characteristics and verification (ISO/DIS 15548-1:2025)
ISO 15548-1:2013 identifies the functional characteristics of a general-purpose eddy current instrument and provides methods for their measurement and verification.
The evaluation of these characteristics permits a well-defined description and comparability of eddy current equipment.
By careful choice of the characteristics, a consistent and effective eddy current examination system can be designed for a specific application.
Where accessories are used, these are characterized using the principles of ISO 15548-1:2013.
ISO 15548-1:2013 gives neither the extent of verification nor acceptance criteria for the characteristics. They are given in the application documents.

L'ISO 15548-1:2013 identifie les caractéristiques fonctionnelles d'un appareil à courants de Foucault à usage général et fournit des méthodes pour les mesurer et les vérifier.
L'évaluation de ces caractéristiques permet de donner une description bien définie de l'appareillage à courants de Foucault et d'assurer la comparabilité entre appareillages.
Un système d'examen par courants de Foucault, cohérent et efficace, peut être conçu en choisissant méticuleusement les caractéristiques pour une application spécifique.
Lorsque des accessoires sont mis en oeuvre, ils sont caractérisés en appliquant les principes de l'ISO 15548-1:2013.
L'ISO 15548-1:2013 ne donne ni l'étendue de la vérification ni les critères d'acceptation des caractéristiques. Celles-ci sont définies dans les documents d'application.
