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.

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.

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.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
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/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 135, Non-destructive testing, Subcommittee
SC 3 Ultrasonic testing.
This second edition cancels and replaces the first edition (ISO 18563-1:2015), which has been technically
revised.
The main changes compared to the previous edition 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 test in ISO 22232-1.
A list of all parts in the ISO 18563 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.

Non-destructive testing — Characterization and verification of
ultrasonic phased array equipment — Part 1: Instruments
1 Scope
This document identifies the functional characteristics of a multi-channel ultrasonic phased array
instrument used for array probes and provides methods for their measurement and verification.
This document can partly be applicable to ultrasonic phased array instruments in automated systems,
but then, other tests might be needed to ensure satisfactory performance. When the phased array
instrument is a part of an automated system, the acceptance criteria can be modified by agreement
between the parties involved.
This document also can partly be applicable to FMC instruments and TFM instruments.
This document gives the extent of the verification and defines acceptance criteria within a frequency
range of 0,5 MHz to 10 MHz.
The evaluation of these characteristics permits a well-defined description of the ultrasonic phased array
instrument and comparability of ultrasonic phased array instruments.

3.2
parallel ultrasonic phased array instrument
ultrasonic phased array instrument featuring a maximum number of channels that can be simultaneously
activated (3.1) equal to the number of channels in the phased array instrument
EXAMPLE In a type 64/64 (also called 64 parallel), the maximum number of channels that can be
simultaneously activated is 64 and the total number of channels of the ultrasonic phased array instrument is 64.
3.3
multiplexed ultrasonic phased array instrument
ultrasonic phased array instrument featuring a maximum number of channels that can be simultaneously
activated (3.1) smaller than the number of channels in the ultrasonic phased array instrument and which
are controlled by an internal multiplexing device
EXAMPLE In a type 16/64 multiplexed ultrasonic phased array instrument, the maximum number of channels
that can be simultaneously activated is 16 and the total number of channels available is 64. See Figure 1.
