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.

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

This document was prepared by Technical Committee ISO/TC 206, Fine ceramics.
This second edition cancels and replaces the first edition (ISO 18753:2004), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— Clause 6 has been modified to include changes in list items d) and g) and to add a paragraph
discussing factors affecting accuracy of test results;
[1]
— Table A.1 has been modified with new reference data for the absolute density of distilled water .

INTERNATIONAL STANDARD ISO 18753:2017(E)
Fine ceramics (advanced ceramics, advanced technical
ceramics) — Determination of absolute density of ceramic
powders by pycnometer
1 Scope
This document specifies a method for determining the absolute particle density of fine ceramic powders
or sintered parts using liquid pycnometry.
NOTE Other pycnometer methods like gas pycnometers (e.g. helium pycnometer), where a gas is used as
media, also exist.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements 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.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at http:// www .iso .org/ obp
— IEC Electropedia: available at http:// www .electropedia .org/
3.1
absolute particle density
absolute density of ceramic powders
density of an individual ceramic particle, a ceramic powder or sintered parts
Note 1 to entry: When an enclosed space occurs (pore) inside the particle or part, the space is considered to be
part of the individual particle or part. The result of the test is then the absolute density of the ceramic particles or
ceramic parts with closed porosity.
Note 2 to entry: If the intention of the test is to determine the absolute density of a ceramic material, the test is
limited to particles or parts without closed porosity.
ISO 18753:2017(E)
3.2
particle
ceramic powder or an amount of small sintered ceramic parts
EXAMPLE Grinding balls or other small parts.
Note 1 to entry: When the examined material has closed porosity inside the particles, the measured density is
not the absolute density of the material but of the examined part.
3.3
pycnometry
method of measuring absolute particle density using a pycnomete
