ISO 13124:2011

Fine ceramics (advanced ceramics, advanced technical ceramics) — Test method for interfacial bond strength of ceramic materials

ISO 13124:2011 specifies a test method for determining the interfacial tensile and shear bond strength of ceramic-ceramic, ceramic-metal, and ceramic-glass joining at ambient temperature by compression tests on cross-bonded test pieces. Methods for test-piece preparation, test modes and rates (load rate or displacement rate), data collection and reporting procedures are addressed. ISO 13124:2011 applies primarily to ceramic materials, including monolithic fine ceramics and whisker-, fibre- or particulate-reinforced ceramic composites. This test method can be used for materials research, quality control, and characterization and design data generation purposes.

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 13124 was prepared by Technical Committee ISO/TC 206, Fine ceramics.

INTERNATIONAL STANDARD ISO 13124:2011(E)

Fine ceramics (advanced ceramics, advanced technical
ceramics) — Test method for interfacial bond strength of
ceramic materials
1 Scope
This International Standard specifies a test method for determining the interfacial tensile and shear bond
strength of ceramic-ceramic, ceramic-metal, and ceramic-glass joining at ambient temperature by
compression tests on cross-bonded test pieces. Methods for test-piece preparation, test modes and rates
(load rate or displacement rate), data collection and reporting procedures are addressed.
This International Standard applies primarily to ceramic materials, including monolithic fine ceramics and
whisker-, fibre- or particulate-reinforced ceramic composites. This test method can be used for materials
research, quality control, and characterization and design data generation purposes.

5 Principle
A cross-bonded sample is loaded in compression which yields tensile or shear stress in the interface until the
occurrence of debonding in the interface. Two different forms of mounting the cross-bonded sample in a
fixture are designed to measure the interfacial tensile and shear bond strength, respectively. In the case of the
former, a uniaxial tensile stress is generated when the testing sample is subjected to a compressive load, as
shown in Figure 2 a). For the latter, a cross-bonded sample is loaded in compression to induce failure by
shear at the interface, as shown in Figure 2 b). The test is usually performed at a constant cross-head
displacement rate. The load at fracture and the bonded area are used to compute the tensile and shear bond
strength.
