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. www.iso.org/directives

ISO 17095 was prepared by Technical Committee ISO/TC 206, Fine ceramics.

1 Scope

This International Standard specifies the method of test for determining the interfacial tensile and shear bond strength of ceramic-ceramic, ceramic-metal, and ceramic-glass joining at elevated temperature by the compression tests on the 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 the 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.

3 Terms and definitions

For the purposes of this document, the following terms and definitions apply.

3.2

cross-bonded sample

testing sample having the form of a symmetrical cross, which is prepared by joining two rectangle bars of the same shape and size

Note 1 to entry: See Figure 1.

Note 2 to entry: The two bars joined to form the cross-bonded sample may be of the same or different materials.

Note 3 to entry: The approach used for joining may be any chemical or physical bonding.

Note 4 to entry: The two bars should be joined perpendicularly and symmetrically within ± 1° (α = 90° ± 1°).
