Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/

This document was prepared by Technical Committee ISO/TC 135, Non-destructive testing, Subcommittee
SC 3, Ultrasonic testing, in collaboration with the European Committee for Standardization (CEN)
Technical Committee CEN/TC 138, Non-destructive testing, in accordance with the Agreement on
technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 18563-1:2015), which has been
technically revised.
The main changes are as follows:
— test methods introduced in ISO 22232-1 have been incorporated;
— the layout has been rearranged to follow the layout of ISO 22232-1;
— the sequence of tests has been modified to follow the sequence of tests in ISO 22232-1.

7 Performance requirements for ultrasonic phased array instruments
In order to fulfil the requirements of this document, ultrasonic phased array instruments shall be
verified with the following tests depending on the situation.
— Group 1 tests: to be performed by the manufacturer (or his or her agent) on a representative sample
of the ultrasonic phased array instruments.
High-level measuring instruments are required for these tests.
— Group 2 tests: to be performed on every ultrasonic phased array instrument:
a) by the manufacturer (or his or her agent) prior to the supply of the ultrasonic phased array
instrument (zero point tests);
b) by the manufacturer, the owner, or a laboratory, at 12-month intervals, to verify the
performance of the ultrasonic phased array instrument during its lifetime;
c) following the repair of the ultrasonic phased array instrument.
Only basic electronic measuring instruments are needed for group 2 tests.
By agreement between the parties involved, these tests may be supplemented with additional tests
from group 1.
A third group of tests for the combined system (ultrasonic phased array instrument and connected
probes) is given in ISO 18563-3, these tests shall be performed at regular intervals on site.
For ultrasonic phased array instruments marketed before the introduction of this document, continuing
fitness for purpose shall be demonstrated by performing the periodic group 2 tests every 12 months.
Following the repair, all parameters which can have been influenced by the repair shall be checked
using the appropriate group 1 or group 2 tests.
Table 3 contains all tests to be performed on ultrasonic phased array instruments.

8.1 Equipment required for group 1 tests
The equipment utilized to obtain the required information shall not affect the characteristics of the
ultrasonic phased array instrument under consideration.
The equipment required for the group 1 tests on ultrasonic phased array instruments includes the
following items or functions:
a) oscilloscope with a minimum bandwidth of 100 MHz;
b) (50 ± 0,5) Ω non-reactive resistors;
c) non-reactive resistors with values R and R
A B;
d) standard 50 Ω attenuator with 1 dB steps and a total range of 100 dB. The attenuator shall have
a cumulative error of less than 0,3 dB in any 10 dB span for signals with a frequency less than or
equal to 15 MHz;
e) switching means;
f) pulse generator, capable of producing a trigger pulse with or without a defined delay;
g) signal generator, capable of producing a defined sinusoidal signal or a sinusoidal burst signal;
NOTE An arbitrary waveform generator can be used to replace one or both of the above listed generators
due to its multifunctional design.
h) protection circuit (see Figure 2);
i) impedance analyser;
j) environmental test chamber;
k) regulated DC power supply (for testing the performances of battery operated ultrasonic phased
array instruments);
l) array probe (2 MHz to 6 MHz);
m) reference block to generate a back-wall echo (e.g. calibration block no. 1 according to ISO 2400).
All of the tests in group 1, except the test for stability against temperature (see 8.4), require electronic
means to produce the necessary signals.
The characteristics and stability of the equipment used shall be adapted to the tests.
Before the oscilloscope is connected to the transmitter of the ultrasonic phased array instrument, as
specified in some of the test procedures in this document, it shall be verified that the oscilloscope will
not be damaged by the high transmitter voltage.

The battery operational time of the unloaded (without any probe connected) ultrasonic phased array
instrument using batteries only shall be measured with the following conditions (i.e. the ultrasonic
phased array instrument shall be disconnected from the main power supply):
a) fully charged new battery(ies);
b) ambient temperature between 20 °C and 30 °C;
c) gain set to mid-gain position;
If the ultrasonic phased array instrument features a screen:
d) display A–scan and S-scan presentations;
e) brightness is set at mid-range.
When made possible by the characteristics of the ultrasonic phased array instrument:
f) pulse repetition frequency set to 1 kHz;
g) 16 channels active simultaneously;
h) 10 delay laws;
i) pulse voltage set to 50 V;
j) pulse width set to 100 ns;
k) time base set to 50 µs.
ISO 18563-1:2022(E)
In all other cases, set those parameters to their typical values.
Parameters that have been modified shall be specified by the manufacturer.
8.2.3 Acceptance criterion
The duration measured shall be higher than or equal to the duration stated in the manufacturer’s
technical specification.
8.3 Stability after warm-up time
8.3.1 Procedure
The procedure for the stability check after warm-up time shall be performed as follows:
a) Program the ultrasonic phased array instrument with one active transmitter channel and one
different active receiver channel.
b) Use the signal from the active transmitter channel as the trigger for the pulse generator.
c) Connect the output from the pulse generator to the trigger input of the signal generator.
d) Connect the signal generator output via the variable attenuator to the active receiver channel, see
Figure 3.
