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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 18265 was prepared by Technical Committee ISO/TC 164, Mechanical testing of metals, Subcommittee
SC 3, Hardness testing.

Introduction
The hardness conversion values given in Table A.1 were obtained in interlaboratory tests by the Verein
Deutscher Eisenhüttenleute (VDEh) (German Iron and Steel Institute) using verified and calibrated hardness
testing machines. Statistically reliable information cannot be given on the uncertainty of these values because
the test conditions were not reproducible, and the number of results used to calculate the mean hardness
values is not known. The conversion values in Table A.1 are in accordance with the information presented in
IC No. 3 (1980) and IC No. 4 (1982) of the European Coal and Steel Community, as well as in ISO 4964:1984
and ISO/TR 10108:1989.
Annexes C, D and E contain — in a revised format — the extensive results on the conversion of hardness
values presented in TGL 43212/02 to 43212/04, standards published by the former East German standards
body, the Amt für Standardisierung, Meßwesen und Warenprüfung (ASMW). The values presented in
Annex B had also been determined by the ASMW, but were published in a report of the Physikalisch-
[1]
Technische Bundesanstalt (PTB) , the German national institute for science and technology, not in a TGL
standard.
The converted hardness values in the above-mentioned TGL standards were obtained in statistically reliable
hardness and tensile tests. The hardness tests were performed using ASMW normal testing machines on
plane-parallel, polished specimens of various materials in different heat treatment conditions. Tensile strength
was tested on machines whose force measuring and extension measuring systems had been calibrated
immediately before testing. The tensile test method used is equivalent to that specified in ISO 6892, and the
calibration procedures conform with those specified in ISO 7500-1 and ISO 9513.
Users of this International Standard should take note of Clause 3, especially the concluding warning.
INTERNATIONAL STANDARD ISO 18265:2003(E)
Metallic materials — Conversion of hardness values
1 Scope
This International Standard specifies the principles of the conversion of hardness values and gives general
information on the use of conversion tables.
The conversion tables in Аnnexes A to F apply to
unalloyed and low-alloy steels and cast iron;
steels for quenching and tempering;
cold working steels;
high speed steels;
hardmetals;
non-ferrous metals and alloys.
NOTE The conversion tables in Annexes B to E are based on empirical results which were evaluated by means of
regression analysis. Such analysis was not possible in the case of the values given in Annex A because a sufficient
number of results was not available.
