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 14577-4 was prepared by Technical Committee ISO/TC 164, Mechanical testing of metals, Subcommittee
SC 3, Hardness testing.
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

ISO 14577-4:2007(E)
Introduction
The elastic and plastic properties of a coating are critical factors determining the performance of the coated
product. Indeed many coatings are specifically developed to provide wear resistance that is usually conferred
by their high hardness. Measurement of coating hardness is often used as a quality control check. Young’s
modulus becomes important when calculation of the stress in a coating is required in the design of coated
components. For example, the extent to which coated components can withstand external applied forces is an
important property in the capability of any coated system.
It is relatively straightforward to determine the hardness and indentation modulus of bulk materials using
instrumented indentation. However, when measurements are made normal to a coated surface, depending on
the force applied and the thickness of the coating, the substrate properties influence the result.
The purpose of this part of ISO 14577 is to provide guidelines for conditions where there is no significant
influence of the substrate, and, where such influence is detected, to provide possible analytical methods to
enable the coating properties to be extracted from the composite measurement. In some cases, the coating
property can be determined directly from measurements on a cross-section.

INTERNATIONAL STANDARD ISO 14577-4:2007(E)

Metallic materials — Instrumented indentation test for hardness
and materials parameters —
Part 4:
Test method for metallic and non-metallic coatings
1 Scope
This part of ISO 14577 specifies a method for testing coatings which is particularly suitable for testing in the
nano/micro range applicable to thin coatings.
This test method is limited to the examination of single layers when the indentation is carried out normal to the
test piece surface, but graded and multilayer coatings can also be measured in cross-section if the thickness
of the individual layers or gradations is greater than the spatial resolution of the indentation process.
The test method is not limited to any particular type of material. Metallic, non-metallic and organic coatings are
included in the scope of this part of ISO 14577.
The application of this part of ISO 14577 regarding measurement of hardness is only possible if the indenter is
a pyramid or a cone with a radius of tip curvature small enough for plastic deformation to occur within the
coating. The hardness of visco-elastic materials, or materials exhibiting significant creep will be strongly
affected by the time taken to perform the test.
NOTE 1 ISO 14577-1, ISO 14577-2 and ISO 14577-3 define usage of instrumented indentation testing of bulk
materials over all force and displacement ranges.
NOTE 2 The application of the method of this part of ISO 14577 is not ne
