Non-destructive testing - Measurement and evaluation of the X-ray tube voltage - Part 2: Constancy check by the thick filter method

Non-destructive testing - Measurement and evaluation of the X-ray tube voltage - Part 2: Constancy check by the thick filter method

This standard specifies a constancy check of a X-ray system where mainly the X-ray voltage is checked and also the tube current and the constitution of the target which can be changing due to ageing of the tube. The thick filter method is based on a measurement of the dose rate behind a defined thick filter using defined distances between the X-ray tube, the filter and the measuring device. This method is very sensitive to changes of the voltage, but it does not provide an absolute value for the X-ray tube voltage.

Zerstörungsfreie Prüfung - Messung und Auswertung der Röntgenröhrenspannung - Teil 2: Konstanzprüfung mit dem Dickfilter-Verfahren

Diese Europäische Norm legt ein Konstanzprüfverfahren für eine Röntgen- anlage fest, wobei die Röntgenspannung besonders empfindlich erfaßt wird, aberauch der Röhrenstrom und der Zustand des Röhrentargets, der einem Alterungsprozeß unterliegen kann. Das Dickfilter-Verfahren basiert auf der Messung der Dosisleistung hinter einem definierten dicken Filter und definiertenAbständen zwischen Röntgenröhre, Filter und Meßinstrument. Dieses Verfahren reagiert sehr empfindlich auf Spannungsänderungen, liefert aber keineAbsolutwerte für die Röntgenröhrenspannung.

Essais non destructifs - Mesurage et évaluation de la tension des tubes radiogènes - Partie 2: Contrôle de la constance selon la méthode du filtre épais

La présente norme décrit une méthode de contrôle de la constance d'un système radiogène; la méthode de contrôle s'applique principalement à la tension du tube et également au courant du tube, à la constitution de la cible, lesquels peuvent subir des variations avec le vieillissement du tube. La méthode du filtre épais est basée sur le mesurage de la dose recueillie derrière un filtre épais défini et selon des distances définies entre le tube, le filtre et l'appareil de mesure.

Non-destructive testing - Characterization and verification of ultrasonic phased array equipment - Part 3: Complete systems (ISO 18563-3:2024)
SIST EN ISO 18563-3:2024

This document addresses ultrasonic test systems implementing array probes, for contact technique (with or without wedge) or for immersion technique, with centre frequencies in the range of 0,5 MHz to 10 MHz.
This document provides methods and acceptance criteria for determining the compliance of the complete system (see 3.2). Its purpose is for the verification of the correct operation of the system prior to testing or verification of the absence of degradation of the system.
The methods are not intended to prove the suitability of the system for particular applications but are intended to prove the capability of the complete system (used for an application) to operate correctly according to the settings used. Tests can be performed on individual ultrasonic beams (for phased array technique, see 9.4.4) or on resulting images (for phased array technique and total focusing technique, see 9.4.3).
The tests can be limited to the functions that are intended to be used for a certain application.
This document does not cover the sensitivity setting of the system for a specific application. Nor does it apply to the characterization or verification of the mechanical scanning equipment. It is intended that these items will be covered by the test procedure.
This document does not address the phased array technique using tandem technique.
The characterization of beams, as recommended in case of dead elements or for more in-depth knowledge of the beams, is presented in Annex A. It is not applicable for signal processing technology using arrays.
NOTE            Unless stated otherwise, in this document ‘TFM’ and ‘TFM technique’ refer to the total focusing technique as defined in ISO 23243, and to related techniques, see for example ISO 23865 and ISO 23234.

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.).

c) leak testing (hydraulic pressure tests excluded);
d) magnetic testing;
e) penetrant testing;
f) radiographic testing;
g) strain gauge testing;

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.

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.
