Non-destructive testing - Characterization and verification of ultrasonic phased array equipment - Part 3: Combined systems (ISO 18563-3:2015)

This part of this European standard addresses non destructive testing ultrasonic systems implementing phased array linear probes, in contact (with or without wedge) or in immersion, with central frequencies in the range of 0.5 – 10 MHz.
It describes methods and acceptance criteria for verifying the performance of an ultrasonic testing system (i.e. the instrument with the probe as defined in part 1 and 2 of this standard) with appropriate standard calibration blocks.
The methods described are suitable for the use by operators working under site or shop floor conditions. The methods only apply to contact techniques (manual or automated) and immersion techniques (automated). The purpose is to verify, prior to an inspection, the correct operation of the complete system in use, to characterize UT beams and verify the absence of degradation in the system performance

Zerstörungsfreie Prüfung - Charakterisierung und Verifizierung der Ultraschall-Prüfausrüstung mit phasengesteuerten Arrays - Teil 3: Vollständige Prüfsysteme (ISO 18563-3:2015)

Dieser Teil von ISO 18563 beschreibt Ultraschallprüfsysteme für die Prüfung mit linearen Phased-Array-Prüfköpfen bei Anwendung der Kontakttechnik (mit oder ohne Vorsatzkeil) oder der Tauchtechnik für Mittenfrequenzen im Bereich von 0,5 MHz bis 10 MHz.
Dieses Dokument legt Verfahren und Zulässigkeitskriterien zur Verifizierung der Leistung vollständiger Prüfsysteme fest (d. h. Prüfgerät, Prüfkopf und Verbindungsabel angeschlossen). Die beschriebenen Verfahren sind für Anwender geeignet, die unter Baustellen- oder Werkstattbedingungen arbeiten. Dieser Teil soll den ordnungsgemäßen Betrieb des Prüfsystems vor der Prüfung verifizieren und außerdem Schallbündel charakterisieren oder verifizieren, dass sich die Leistung des Prüfsystems nicht verschlechtert hat.
Diese Verfahren sind nicht dafür vorgesehen die Eignung des Prüfsystems für besondere Anwendungen nachzuweisen, sondern sind dafür vorgesehen nachzuweisen, dass mit dem vollständigen Prüfsystem den Einstellungen entsprechende Schallbündel erzeugt werden können.
Die Justierung des Systems für eine bestimmte Anwendung liegt außerhalb des Anwendungsbereiches dieses Teils von ISO 18563 und sollte durch die Prüfanweisung abgedeckt sein.
Dieser Teil von ISO 18563 gilt nicht für die folgenden Fälle:
—   umschließende Arrays;
—   Reihen von Aperturen mit einer unterschiedlichen Anzahl von Elementen;
—   verschiedene Einstellungen zum Senden und Empfangen (z. B. aktive Apertur, Anzahl der aktiven Elemente, Verzögerungen);
—   Verfahren, bei denen die Signale der einzelnen Elemente auf komplexere Art als mit einem einfachen Verzögerungsgesetz nachbearbeitet werden (z. B. Erfassung einer gesamten Matrix).

Essais non destructifs - Caractérisation et vérification de l'appareillage ultrasonore multi-éléments - Partie 3: Appareillage complet (ISO 18563-3:2015)

ISO 18563-3:2015 concerne l'appareillage d'essais par ultrasons équipé de traducteurs linéaires multiéléments, en contact (avec ou sans sabot) ou en immersion, avec des fréquences centrales comprises entre 0,5 MHz et 10 MHz.
Elle décrit les méthodes et les critères d'acceptation applicables à la vérification des performances de l'équipement complet (à savoir appareil, traducteur et câbles connectés). Les méthodes décrites conviennent aux utilisateurs travaillant sur site ou en usine. L'objectif de la présente partie est de vérifier le bon fonctionnement du système avant les essais, et également de caractériser les faisceaux acoustiques ou de vérifier l'absence de dégradation du système.
Les méthodes ne sont pas destinées à démontrer l'adéquation du système avec des applications particulières mais à confirmer l'aptitude du système complet à générer des faisceaux acoustiques en fonction des réglages utilisés.
L'étalonnage du système pour une application spécifique ne fait pas partie du domaine d'application de la présente partie de l'ISO 18563 et est censé être couvert par le mode opératoire d'essai.
ISO 18563-3:2015 ne concerne pas les cas suivants :
-      réseaux encerclants ;
-      séries d'ouvertures ayant différents nombres d'éléments ;
-      différents réglages pour l'émission et la réception (par exemple, ouverture active, nombre d'éléments actifs, retards) ;
-      techniques utilisant le post-traitement des signaux d'éléments individuels de manière plus complexe qu'une simple loi de retards (par exemple, acquisition de la matrice intégrale).

Neporušitveno preskušanje - Ugotavljanje značilnosti in preverjanje ultrazvočne opreme faznih sistemov - 3. del: Kombinirani sistemi (ISO 18563-3:2015)

Ta del tega evropskega standarda obravnava sonde linearnega faznega niza, ki se uporabljajo za ultrazvočna neporušitvena preskušanja, s kontaktom (s klinom ali brez njega) ali z imerzijo, z osrednjimi frekvencami v razponu od 0,5 do 10 MHz. Opisuje metode in kriterije sprejemljivosti za preverjanje delovanja ultrazvočnega preskusnega sistema (tj. instrument s sondo, kot je določen v 1. in 2. delu tega standarda) s primernimi standardnimi ploščicami za umerjanje. Opisane metode so primerne za izvajalce, ki delajo v razmerah na terenu ali na delovnem mestu. Metode veljajo le za tehniko s kontaktom (ročno ali avtomatizirano) in imerzno tehniko (avtomatizirano). Namen je pred pregledom preveriti pravilno delovanje celotnega sistema v uporabi, ugotoviti značilnosti UT tramov ter preveriti morebitno zmanjšanje zmogljivosti delovanja sistema.

Part 3:
Combined systems
1 Scope
This part of ISO 18563 addresses ultrasonic test systems implementing linear phased array probes, in
contact (with or without wedge) or in immersion, with centre frequencies in the range of 0,5 MHz–10 MHz.
It provides methods and acceptance criteria for verifying the performance of combined equipment
(i.e. instrument, probe and cables connected). The methods described are suitable for users working
under on-site or shop floor conditions. Its purpose is for the verification of the correct operation of the
system prior to testing, and also the characterization of sound beams 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 combined equipment to generate ultrasonic beams according to
the settings used.
The calibration of the system for a specific application is outside of the scope of part of ISO 18563 and it
is intended that it be covered by the test procedure.
This part of ISO 18563 does not address the following:
— encircling arrays;
— series of apertures having a different number of elements;
— different settings for transmitting and receiving (e.g. active aperture, number of active elements,
delays);
— techniques using post-processing of the signals of individual elements in a more complex manner
than a simple delay law (e.g. full matrix capture).

5 General requirements for conformity
The tests to be performed prior to the first use of the system for a given application (mode of operation
and settings) are described in Clause 8 (Group 1 tests) and in Clause 9 (Group 2 tests), except the tests
described in 9.3, 9.8 and 9.9 which are already performed for Group 1.
When all tests are successful, the system is considered to conform to this part of ISO 18563 and becomes
a reference system. If no component and/or setting of the system is modified or replaced, it remains a
reference system. Using the system with other settings does not void the reference system, if the original
settings can be restored. The results of the tests shall be reported on the system record sheet.
On a system identical to a reference system, only the Group 2 tests have to be performed. When all
tests are successful, the system is considered to conform to this part of ISO 18563. During the first
performance of the tests, the system record sheet is initialized with the values obtained on the reference
system and is completed with the values obtained after the tests.
The Group 2 tests have then to be performed periodically, on any system, on workshop or on site. After
each performance of the Group 2 tests, the system record sheet shall be updated.
Table 2 presents the different tests to be performed on a system, featuring an immersion or contact probe.
A summary of all tests to be carried out, including their acceptance criteria, is given in Table A.1.

6 Modes of operation
During ultrasonic testing with phased arrays, a set of beams is generally produced from each position
of the probe.
Each beam corresponds to one shot, each being defined by the active aperture and by the delay laws
applied. The modes of operation are characterized by the number of apertures (one or multiple) and the
number of shots per aperture (one or multiple).
The tests described only address applications in which the transmitting elements are also receiving.
In the scope of this standard, only one received signal is considered for each shot.
Depending on the application the following variants of phased array technique (modes of operation)
can be used/combined:
— number of active apertures (one or multiple);
— number of shots or delay laws (one or multiple) per active aperture;
— type of delay law (beam steering, beam focusing or combined).
If multiple active apertures are used, then the same set of delay laws may be used for all active
apertures, or a different set of delay laws may be used for each active apertures. The latter may be
required to compensate for the orientation of the array relative to the object surface (wedge angle for
contact technique, array tilt for immersion technique).
The verification tests for the different modes shall be performed as follows:
Mode 1
— Only one beam is created.
— Tests are performed with this beam.
Mode 2
— Multiple beams are created with the sa

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 18563-3:2015(E)
Non-destructive testing — Characterization and
verification of ultrasonic phased array equipment —
Part 3:
Combined systems
1 Scope
This part of ISO 18563 addresses ultrasonic test systems implementing linear phased array probes, in
contact (with or without wedge) or in immersion, with centre frequencies in the range of 0,5 MHz–10 MHz.
It provides methods and acceptance criteria for verifying the performance of combined equipment
(i.e. instrument, probe and cables connected). The methods described are suitable for users working
under on-site or shop floor conditions. Its purpose is for the verification of the correct operation of the
system prior to testing, and also the characterization of sound beams 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 combined equipment to generate ultrasonic beams according to
the settings used.
The calibration of the system for a specific application is outside of the scope of part of ISO 18563 and it
is intended that it be covered by the test procedure.
This part of ISO 18563 does not address the following:
— encircling arrays;
— series of apertures having a different number of elements;
— different settings for transmitting and receiving (e.g. active aperture, number of active elements, delays);
— techniques using post-processing of the signals of individual elements in a more complex manner
than a simple delay law (e.g. full matrix capture).

5 General requirements for conformity
The tests to be performed prior to the first use of the system for a given application (mode of operation
and settings) are described in Clause 8 (Group 1 tests) and in Clause 9 (Group 2 tests), except for the
tests described in 9.3, 9.8 and 9.9, which are already performed for Group 1.
When all tests are successful, the system is considered to conform to this part of ISO 18563 and becomes
a reference system. If no component and/or setting of the system is modified or replaced, it remains a
reference system. Using the system with other settings does not void the reference system, if the original
settings are restored. The results of the tests shall be reported on the system record sheet.
On a system identical to a reference system, only the Group 2 tests have to be performed. When all
tests are successful, the system is considered to conform to this part of ISO 18563. During the first
performance of the tests, the system record sheet is initialized with the values obtained on the reference
system and is completed with the values obtained after the tests.
The Group 2 tests have then to be performed periodically, on any system, on workshop or on site. After
each performance of the Group 2 tests, the system record sheet shall be updated.
Table 2 presents the different tests to be performed on a system, featuring an immersion or contact probe.
A summary of all tests to be carried out, including their acceptance criteria, is given in Table A.1.

6 Modes of operation
During ultrasonic testing with phased arrays, a set of beams is generally produced from each position
of the probe.
Each beam corresponds to one shot, each being defined by the active aperture and by the delay laws
applied. The modes of operation are characterized by the number of apertures (one or multiple) and the
number of shots per aperture (one or multiple).
The tests described only address applications in which the transmitting elements are also receiving.
In the scope of this standard, only one received signal is considered for each shot.
Depending on the application the following variants of phased array technique (modes of operation) can
be used/combined:
— number of active apertures (one or multiple);
— number of shots or delay laws (one or multiple) per active aperture;
— type of delay law (beam steering, beam focusing or combined).
If multiple active apertures are used, then the same (set of) delay laws may be used for all active
apertures, or a different (set of) delay laws may be used for each active apertures. The latter may be
required to compensate for the orientation of the array relative to the object surface (wedge angle for
contact technique, array tilt for immersion technique).
The verification tests for the different modes shall be performed as follows.
Mode 1
— Only one beam is created.
— Tests are performed with this beam.
Mode 2
— Multiple beams are created with the same active aperture.

— Tests are performed with a minimum of three beams corresponding to the extremes and median
delay laws.
Mode 3
— Only applicable for an array parallel to the test surface.
— Multiple active apertures are used, all using the same delay law.
— Tests are performed with a minimum of one aperture.
Mode 4:
— Multiple active apertures are used, all using the same set of delay laws.
— Tests are performed with a minimum of one aperture and with a minimum of three beams
corresponding to the extremes and median delay laws.
Mode 5
— Multiple active apertures are used, all using a single delay law but different for each active aperture.
— Alternatively, multiple active apertures are used, all using the same delay law, if the array is not
parallel to the test surface.
— Tests are performed with a minimum of three apertures corresponding to the extreme and
median positions.
Mode 6
— Multiple active apertures are used, each using a different set of delay laws.
— Tests are performed with a minimum of three apertures corresponding to the median and extreme
positions and, for each of these apertures, on three beams corresponding to the extremes and
median delay laws.
The modes are described and illustrated in Table 3.
