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).

technical cooperation between ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 7963:2006), which has been technically
revised.
The main changes are as follows:
— document structure aligned with ISO 2400;
— normative references updated;
— wording updated;
— Annex A deleted and the relevant information shifted to the main text;
— Figures 1, 3 and 6 corrected;
— tempering aligned with ISO 2400.

Introduction
Calibration block No. 2 is made of steel and may be used for all ultrasonic testing, as calibration
block No. 1 described in ISO 2400.
Calibration block No. 2 differs in size and shape from calibration block No.1 but is made from the same
material.
Calibration block No. 2 is much smaller and lighter, and its geometry is much simpler than block No 1.
Calibration block No. 2 does not offer as much scope as the larger block No.1; in particular it is not
meant to check an ultrasonic instrument completely.
However, calibration block No. 2 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 miniature angle-beam probes.
The International Institute of Welding (IIW) and its members developed the designs of steel calibration
blocks in the 1950s and 1960s 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.
The smaller type block is sometimes indicated as “Rompas block” or “miniature angle-beam block
(MAB)”, respectively named after the original Dutch designer or the intended use.
Some commercially available blocks look similar to calibration block No. 2, however
