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 on the ISO list of
patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the World
Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following URL:

Fine ceramics (advanced ceramics, advanced technical
ceramics) — Methods of test for reinforcements —
Determination of tensile properties of filaments at ambient
temperature
1 Scope
This document specifies the conditions for the determination of tensile properties of single filaments of
ceramic fibre such as tensile strength, Young modulus and fracture strain.
The method applies to continuous ceramic filaments taken from tows, yarns, braids and knittings, which
have strain to fracture less than or equal to 5 %.
The method does not apply to carbon fibres that exhibit nonlinear stress-strain curve. The method does
not apply to checking the homogeneity of strength properties of fibres, or to assessing the effects of volume
under stress. Methods of estimation of strength statistical parameters are indicated.
