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

This document determines the guidelines and the specifications 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 part to be tested, for the scanning conditions, for the recording, the processing and the interpretation of the results are specified. Acceptance criteria are not defined.
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 9712:2022)
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 - Ultrasonic testing - Examination for loss of thickness due to erosion and/or corrosion using the TOFD technique
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 or erosion damage, particularly those defined in ISO 16809.
This test applies to unalloyed or low-alloyed steel materials.
It applies to components with a nominal thickness ≥ 6 mm. For smaller thicknesses feasibility tests will be performed to validate the technique.
For other materials, feasibility tests are essential too.
The TOFD technique can be used here as a stand-alone technique or in combination with other non-destructive testing techniques, during manufacturing and for testing in-service, in order to detect material loss caused by erosion and/or corrosion.
This technique is based on analysis of TOFD images established using reflected and/or diffracted ultrasonic signals.
This document does not specify acceptance levels.

This document specifies methods for routine verification of the performance of acoustic emission (AE) equipment comprising one or more sensing channels. It is intended for use by operators of the equipment under laboratory conditions. 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 described 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 - Penetrant testing - Part 1: General principles (ISO 3452-1:2021)
EN ISO 3452-1:2021

This standard defines 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. 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 they are not excessively porous, examples of which are castings, forgings, welds, ceramics, etc.
This standard is not intended to be used for acceptance criteria and gives no information relating to the suitability of individual test systems for specific applications nor requirements for test equipment.
The term 'discontinuity' is used here in the sense that no evaluation concerning acceptability or non-acceptability is included.
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.
