Non-destructive testing - Ultrasonic testing - Testing for discontinuities perpendicular to the surface (ISO/DIS 16826:2024)

Non-destructive testing - Ultrasonic testing - Testing for discontinuities perpendicular to the surface (ISO/DIS 16826:2024)

ISO 16826:2012 defines the principles for tandem‑ and longitudinal-longitudinal-transverse (LLT) wave‑examination for the detection of discontinuities perpendicular to the surface.
The general principles required for the ultrasonic examination of industrial products are described in ISO 16810. A list of symbols and equations is given in ISO 16811.
The tandem‑ or LLT‑examination should be used for the detection of planar discontinuities with distance to the surface greater than 15 mm. ISO 16826:2012 has been prepared for the examination of metallic materials with a thickness between 40 mm and 500 mm with parallel or concentric surfaces. It can, however, be used for other materials and smaller thickness provided special measures are taken.

Essais non destructifs - Contrôle par ultrasons - Contrôle des discontinuités perpendiculaires à la surface (ISO/DIS 16826:2024)

L'ISO 16826:2012 définit les principes généraux du contrôle par les techniques du tandem et des ondes longitudinales et longitudinales-transversales (LLT) pour la détection des discontinuités perpendiculaires à la surface.
Les principes généraux du contrôle par ultrasons des produits industriels sont décrits dans l'ISO 16810. La liste des symboles et des équations est donnée dans l'ISO 16811.
Il convient d'utiliser le contrôle en tandem ou LLT pour détecter des discontinuités planes situées à plus de 15 mm de la surface. La présente Norme internationale a été élaborée pour contrôler les matériaux métalliques dont l'épaisseur est comprise entre 40 mm et 500 mm, et ayant des surfaces parallèles ou concentriques. Elle peut toutefois être utilisée pour d'autres matériaux et des épaisseurs inférieures, à condition que des mesures spécifiques soient prises.

Non-destructive testing - Thermographic testing - Active thermography with laser excitation
SIST EN 17501:2022

This document specifies a method and establishes guidelines for non-destructive testing using active thermography with laser excitation.
Active thermography with laser excitation is mainly applicable, but not limited, to different materials (e.g. composites, metals, ceramics) and to:
- the detection of surface-breaking discontinuities, particularly cracks;
- the detection of discontinuities located just below the surface or below coatings with an efficiency that diminishes rapidly with a few mm depth;
- the detection of disbonds and delamination parallel to the examined surface;
- the measurement of thermal material properties, like thermal diffusivity;
- the measurement of coating thickness.
The requirements for the equipment, for the verification of the system, for the surface condition of the test object, for the scanning conditions, for the recording, the processing and the interpretation of the results are specified. This document does not apply to the definition of acceptance criteria.
Active thermography with laser excitation can be applied in industrial production as well as in maintenance and repair (vehicle parts, engine parts, power plant, aerospace, etc.).

Non-destructive testing - Qualification and certification of NDT personnel (ISO 9712:2021)
SIST EN ISO 9712:2022

This document specifies requirements for the qualification and certification of personnel who perform industrial non-destructive testing (NDT) in the following methods.
a) acoustic emission testing;
b) eddy current testing;
c) leak testing (hydraulic pressure tests excluded);
d) magnetic testing;
e) penetrant testing;
f) radiographic testing;
g) strain gauge testing;
h) thermographic testing;
i) ultrasonic testing;
j) visual testing (direct unaided visual tests and visual tests carried out during the application of another NDT method are excluded).
The system specified in this document is also applicable to other NDT methods or to NDT techniques within an established NDT method, provided a comprehensive scheme of certification exists and the NDT method or NDT technique is covered by international, regional or national standards or the NDT method or the NDT technique has been demonstrated to be effective to the satisfaction of the certification body.
NOTE 1    The term "industrial" implies the exclusion of applications in the field of medicine.
NOTE 2    CEN/TR 14748 provides guidance on the methodology for qualification of non-destructive tests.
NOTE 3    This document specifies requirements for what are, in effect, third party conformity assessment schemes. These requirements do not directly apply to conformity assessment by second or first parties, but relevant parts of this document can be referred to in such arrangements.
NOTE 4    The term “direct unaided visual testing” implies where there is an uninterrupted optical path from the observer’s eye to the test area and the observer uses no tools or devices (e.g. mirror, endoscope, fibre optic).
NOTE 5    Calculations of strain based on other NDT methods are excluded.

Non-destructive testing - Acoustic emission testing - Equipment characterisation - Part 2: Verification of operating characteristics
SIST EN 13477-2:2021

This document specifies test routines for the periodic verification of the performance of acoustic emission (AE) test equipment, i.e. sensors, pre-amplifiers, signal processors, external parametric inputs.
It is intended for use by qualified personnel to implement an automated verification process.
Verification of the measurement characteristics is advised after purchase of equipment, in order to obtain reference data for later verifications. Verification is also advised after repair, modifications, use under extraordinary conditions, or if one suspects a malfunction.
The procedures specified in this document do not exclude other qualified methods, e.g. verification in the frequency domain. These procedures apply in general unless the manufacturer specifies alternative equivalent procedures.
Safety aspects of equipment for use in potentially explosive zones are not considered in this document.

Non-destructive testing - Ultrasonic testing - Examination for loss of thickness due to erosion and/or corrosion using the TOFD technique
SIST EN 17290:2021

This document specifies the application of the time-of-flight diffraction (TOFD) technique in testing of metals for quantifying loss of thickness due to erosion and/or corrosion.
This document applies to all types of corrosion and/or erosion damage, particularly those defined in EN ISO 16809.
This document applies to unalloyed or low-alloyed steels.
It applies to components with a nominal thickness ≥ 6 mm. For smaller thicknesses, feasibility tests are performed to validate the test technique.
For other materials, feasibility tests are essential, too.
The TOFD technique can be used as a stand-alone technique or in combination with other non-destructive testing techniques, for in-service testing, in order to detect material loss caused by erosion and/or corrosion.
This technique is based on analysis of TOFD images using reflected and/or diffracted ultrasonic signals.
This document does not specify acceptance levels.

SIST EN ISO 3452-1:2021

This document specifies a method of penetrant testing used to detect discontinuities, e.g. cracks, laps, folds, porosity and lack of fusion, which are open to the surface of the material to be tested using white light or UV-A (365 nm) radiation. It is mainly applied to metallic materials, but can also be performed on other materials, provided that they are inert to the test media and not excessively porous (castings, forgings, welds, ceramics, etc.)
This document also includes requirements for process and control testing, but is not intended to be used for acceptance criteria. It gives neither information relating to the suitability of individual test systems for specific applications nor requirements for test equipment.
NOTE 1   Methods for determining and monitoring the essential properties of penetrant testing products to be used are specified in ISO 3452-2 and ISO 3452-3.
NOTE 2   The term "discontinuity" is used in this document in the sense that no evaluation concerning acceptability or non-acceptability is included.
NOTE 3   CEN/TR 16638 addresses penetrant testing using actinic blue light.
