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

INTERNATIONAL STANDARD ISO 17162:2014(E)
Fine ceramics (advanced ceramics, advanced technical
ceramics) — Mechanical properties of monolithic ceramics
at room temperature — Determination of compressive
strength
1 Scope
This International Standard specifies a method for the determination of nominal compressive strength
of advanced monolithic technical ceramic materials at room temperature.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
nominal compressive strength
σ
c,m
maximum nominal stress supported by the material at the instant of failure when loaded in linear elastic
compression
4 Significance and use
Advanced technical ceramics are used for applications in which their corrosion resistance, their high
temperature stability, their potential for light-weight constructions, and their high nominal compressive
strength can be utilized in an ideal manner. For application of ceramic components, it shall be considered
that they are loaded mainly with compressive stresses since this type of loading is considerably less
critical than probably appearing tensile stresses.
This International Standard describes the background for a directed material development, quality
control, and for component-optimised applications. It ensures the determination of comparable nominal
compressive strength data.
oSIST prEN ISO 17162:2025
ISO 17162:2014(E)
The result obtained from a compression strength test is determined by a large number of factors
associated with the microstructure of the material, the surface finishing procedure applied for the
preparation of the test pieces, the size and shape of the test piece, the rate of load application, and the
relative humidity of the ambient atmosphere. Furthermore, the result obtained from a strength test is
influenced by possible existing misfit of ram and test piece cross section as well as of elastic constants.
These factors are minimized by a sophisticated test assembly in ASTM C 1424-04 [1]. With respect to an
applicable and reproducible procedure of the measurement, it is consciously abstained from the adoption
of this test assembly. The test assembly defined in this International Standard represents an alternative
to the above mentioned ASTM C 1424-04 [1] that is approved and feasible in industrial practice.
As a consequence of the brittle nature of ceramics, there is usually a considerably range of results
obtained from a number of nominal identical test pieces. The factors (mentioned above) combined mean
that caution in the interpretation of test results is required. For many purposes, and as described in
this International Standard, the results of strength test can be described in terms of a mean value and a
standard deviation. Further statistical evaluation of results is required for design data acquisition, and
can be desirable for other purposes (see EN 843-5).
This method places closely defined restrictions on the size and shape of the test pieces and on the
function of the test apparatus in order to minimize the errors that can arise as a consequence of the test
method.
5 Apparatus
5.1 Test machine
A test machine shall be used that conforms to the safety requirements defined in ISO 7500-1 and
ISO 7500-1 Amendment 1. The test jig shall be surrounded by an adequate shatter protection device.
The test machine shall be capable of applying the force at a constant loading or displacement rate.
The machine shall be equipped to continuously record the force applied to the test piece including the
maximum force applied to the test piece. The accuracy of the test machine shall be in accordance with
ISO 7500-1, grade 1.
5.2 Test jig
The test jig shall be capable to perform compression tests and ensure to meet the requirements described
below.
In Figure 1 an example of a test jig is shown and in Figure 2 a schematic representation of the test jig
including a compression platen with calotte for self-alignment.

The two compression platens shall be aligned axially to the load line of the test machine. The loading
surfaces of the upper and lower compression platens shall be parallel to each other within 0,01 mm per
10 mm and perpendicular to the load line of the test machine.
For a better alignment, one of the compression platens should have a calotte for self-alignment.
Hardness and Young’s modulus of the loading blocks and compression platens shall be larger than or
equal to the hardness and Young’s modulus (≥400 GPa, e.g. silicon carbide or cemented carbide) of the
test piece.
Loading blocks positioned between compression platens and the test piece as shown in Figures 1 and 2
shall be used to minimize mismatches between compression platens and test piece and to protect the
compression platens against damage. Loading blocks could be made from the same material as the test
pieces.
The surface of the compression platen that is in contact with the loading block shall be larger than the
surface of the loading block that is in contact with the compression platen. The cross section of the
contact surface of the loading blocks shall be at least five times greater than the cross sections of the
contact surfaces (end faces) of the test piece. The loadin
