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

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 7963:2006), which has been technically

revised.
The main changes compared to the previous edition 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.

Any feedback or questions on this document should be directed to the user’s national standards body. A

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 as 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 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.

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 such blocks are not

necessarily according to this document and can have different features, dimensions or materials.

The details of calibration block No. 2, as specified in this document, have been adapted over time.
