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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
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 third edition cancels and replaces the second edition (ISO 2400:2012), which has been technically
revised.
The main changes are as follows:
— the wording “calibration block” is replaced by “standard block”;
— the wording “calibrating” is replaced by “setting”;
— the velocities shall be determined in three perpendicular directions;
— a maximum allowed difference between determined velocities is given;
— a link to a CAD file of the standard block has been added.
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.

Introduction
Standard block No. 1 is made of steel and may be used for all ultrasonic testing.
Standard block No. 1 makes it possible to check an ultrasonic instrument completely.
Standard block No. 1 makes it possible, during practical testing, to check simply, from time to time, the
setting of the time base and the sensitivity of the ultrasonic instrument. Moreover, it is suited to check the
beam angle and the probe index point of angle-beam probes.
A smaller and lighter standard block No. 2, which has simpler geometry and offers less scope, is described in
ISO 7963.
The International Institute of Welding (IIW) and its members developed the designs of steel calibration
blocks in the 1950’s and 1960’s which were originally indicated as “IIW calibration block 1” and “IIW
calibration block 2”. These designs have been adopted widely and they form the basis of many blocks
currently available.
Some commercially available blocks look similar to standard block No. 1, however such blocks are not
necessarily according to this document and can have different features, dimensions or materials.
The details of standard block No. 1, as specified in this document, have been adapted over time.
