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.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers

INTERNATIONAL STANDARD ISO 17172:2014(E)
Fine ceramics (advanced ceramics, advanced technical
ceramics) — Determination of compaction properties of
ceramic powders
1 Scope
This International Standard specifies the test method to determine the extent to which granulated or
ungranulated ceramic powders are compacted, when subjected to uniaxial compressive loading in a
confining die, under specified conditions.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
ISO/IEC 17025, General requirements for the competence of testing and calibration laboratories
3 Principle
Granulated or ungranulated ceramic powders are compacted uniaxially in a confining die by double-
action pressing (mode 1) or by single-action pressing (mode 2). Samples of the ceramic powders can be
pressed either at a single specified pressure or at a series of specified pressures. After ejection from die,
the apparent density of the ceramic powder compact is determined.
The apparent density obtained in the former case represents the compaction properties of the ceramic
powder at the specified pressure. The apparent densities obtained in the latter case are utilized for
drawing the compaction curve of the ceramic powder, which is a plot of apparent density as a function
of compaction pressure.
4 Symbols and designation
Symbol Designation Unit
ρ Apparent density g/cm
a
m Mass of ceramic powder compact g
V Volume of ceramic powder compact cm
If the apparent density is measured at only one specified pressure, for example 100 MPa, the symbol
becomes ρ (100).

5 Apparatus
5.1 Cylindrical die, should be made from hard material, preferably hardened steel or tungsten carbide.
The die shall contain two upper and lower punches for producing cylindrical powder compacts and shall
be of the floating type or of the type suspended from a spring (mode 1), or of stationary type with only
one movable upper punch (mode 2). The die shall be capable of making cylindrical powder compacts
with a diameter from 10 mm to 26 mm and a height to diameter ratio between 0,3 and 0,5 (mode 1),
or with a diameter from 10 mm to 32 mm and a height to diameter ratio between 0,15 and 0,25 (mode
