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 3.
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.
International Standard ISO 2738 was prepared by Technical Committee ISO/TC 119, Powder metallurgy,
Subcommittee SC 3, Sampling and testing methods for sintered metal materials (excluding hardmetals).
This third edition cancels and replaces the second edition (ISO 2738:1987) which has been technically revised.

INTERNATIONAL STANDARD  © ISO ISO 2738:1999(E)
Sintered metal materials, excluding hardmetals — Permeable
sintered metal materials — Determination of density, oil content
and open porosity
1 Scope
This international Standard specifies methods of determining the density, oil content and open porosity of
permeable sintered metal materials.
It applies in particular to porous metal bearings and to structural parts produced by pressing and sintering metal
powders.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
publications do not apply. However, parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent editions of the normative documents indicated below. For
undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC
maintain registers of currently valid International Standards.
ISO 758, Liquid chemical products for industrial use — Determination of density at 20 °C.
