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 17092 was prepared by Technical Committee ISO/TC 206, Fine ceramics.

INTERNATIONAL STANDARD ISO 17092:2005(E)

Fine ceramics [advanced ceramics, advanced technical
ceramics] — Determination of corrosion resistance of
monolithic ceramics in acid and alkaline solutions
1 Scope
This International Standard describes the test method for determining the corrosion resistance of fine
ceramics in acid and alkaline solutions, such as sulfuric acid and sodium hydroxide. This International
Standard is designed to provide an assessment of the mass changes and dimensional changes of test
specimens following the corrosion test immersed in the corrosive liquids, and to assess whether corrosion has
a significant effect on the subsequent strength. This test method may be used for development of materials,
quality control, characterization, and design-data generation purposes.
NOTE The units and numerical values given in { } in this standard are based on traditional units and are appended
for information.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
corrosion resistance
resistance against corrosion of fine ceramic material due to reaction with corrosive species in the surrounding
environment, including chemical reactions at grain boundaries and secondary phases
ISO 17092:2005(E)
3.2
flexural strength
maximum nominal stress at fracture of a specified elastic beam loaded in bending
4 Apparatus
4.1 Corrosion testing apparatus, for example, any suitable apparatus capable of maintaining the test
solution in a quiet boiling state and also maintaining the test solution at a constant concentration
The test container shall be made of glass or polytetrafluoroethylene, and shall have a capacity of about 1 litre.
The test container should be connected to a glass vertical-type condenser, having a sufficient cooling area, by
a tapered ground joint. The test apparatus shall be equipped with a thermometer for monitoring the solution
temperature. Since the severe boiling state may cause mechanical damage to test specimens, the “quiet
boiling state” is preferable.
NOTE 1 A device, such as a basket or a system of suspension wires resistant to the corrosive medium, may be used to
prevent contact between test specimens, and to raise them off the bottom of the vessel.
Alternatively, the test specimens may be placed in a PTFE-lined chemical digestion vessel with the reagent, sealed and
heated to the required test temperature. If this approach is employed, it shall be recorded in the test report.
NOTE 2 “Quiet boiling” refers to the level of bubble (vapour) formation in the liquid at a low enough level and frequency
to eliminate movement of the test specimen.
4.2 Drying
