Non-destructive testing - Ultrasonic testing - Time-of-flight diffraction technique as a method for detection and sizing of discontinuities

ISO 16828:2012 defines the general principles for the application of the time-of-flight diffraction (TOFD) technique for both detection and sizing of discontinuities in low alloyed carbon steel components. It can also be used for other types of materials, provided the application of the TOFD technique is performed with necessary consideration of geometry, acoustical properties of the materials, and the sensitivity of the examination. Although it is applicable, in general terms, to discontinuities in materials and applications covered by ISO 16810, it contains references to the application on welds. This approach has been chosen for reasons of clarity as to the ultrasonic probe positions and directions of scanning. Unless otherwise specified in the referencing documents, the minimum requirements of ISO 16828:2012 are applicable. Unless explicitly stated otherwise, ISO 16828:2012 is applicable to the following product classes as defined in ISO 16811: a) class 1, without restrictions; b) classes 2 and 3, restrictions apply as stated in Clause 9. The inspection of products of classes 4 and 5 requires special procedures. These are also addressed in Clause 9. Techniques for the use of TOFD for weld inspection are described in ISO 10863. The related acceptance criteria are given in ISO 15626.

Non-destructive testing - Ultrasonic examination - Part 6 : time-of-flight diffraction technique as a method for detection and sizing of discontinuities

Le présent document définit les principes généraux pour l'application de la technique de diffraction du temps de vol (TOFD) pour la détection et le dimensionnement des discontinuités dans les composants en acier au carbone faiblement allié. Il peut également être employé pour d'autres types de matériaux, à condition que l'application de la technique TOFD tienne compte de la géométrie, des propriétés acoustiques des matériaux et de la sensibilité de l'examen. Sauf dispositions contraires explicites, le présent document s'applique aux classes de produits définies dans la norme NF EN 583-2 (classes 1, 2 et 3). Les techniques d'utilisation de la méthode TOFD pour l'examen des soudures sont décrites dans la norme expérimentale XP CEN/TS 14751.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
