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.

The committee responsible for this document is ISO/TC 164, Mechanical testing of metals, Subcommittee
SC 3, Hardness testing.
This third edition cancels and replaces the second edition (ISO 14577-3:2015), which has been technically
revised.
ISO 14577 consists of the following parts, under the general title Metallic materials — Instrumented
indentation test for hardness and materials parameters:
— Part 1: Test method
— Part 2: Verification and calibration of testing machines
— Part 3: Calibration of reference blocks
— Part 4: Test method for metallic and non-metallic coatings
— Part 5: Linear elastic dynamic instrumented indentation testing (DIIT)

Introduction
Hardness has typically been defined as the resistance of a material to permanent penetration by another
harder material. The results obtained when performing Rockwell, Vickers, and Brinell tests are determined
after the test force has been removed. Therefore, the effect of elastic deformation under the indenter has
been ignored.
ISO 14577 (all parts) has been prepared to enable the user to evaluate the indentation of materials by
considering both the force and displacement during plastic and elastic deformation. By monitoring
the complete cycle of increasing and removal of the test force, hardness values equivalent to traditional
hardness values can be determined. More significantly, additional properties of the material such as its
indentation modulus and elasto-plastic hardness can also be determined. All these values can be calculated
without the requirement to measure the indent optically. Furthermore, by a variety of techniques, the
instrumented indentation test allows to record hardness and modulus depth profiles within a, probably
complex, indentation cycle.
ISO 14577 (all parts) has been written to allow a wide variety of post test data analysis.

3 Manufacture of reference blocks
3.1 The block shall be specially prepared and the attention of the manufacturer drawn to the requirement
to use a manufacturing process that gives the necessary homogeneity, uniformity, and stability of structure.
3.2 Each block being calibrated shall be of a thickness greater or equal to that given in the table 1.
