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 3928 was prepared by Technical Committee ISO/TC 119, Powder metallurgy,
Subcommittee SC 3, Sampling and testing methods for sintered metal materials (excluding hardmetals).
This second edition cancels and replaces the first edition (ISO 3928:1977) which has been technically revised.
Annex A of this International Standard is for information only.

Sintered metal materials, excluding hardmetals —
Fatigue test pieces
1 Scope
This International Standard specifies:
 the die cavity dimensions used for making fatigue test pieces by pressing and sintering, together with certain
dimensions of the test piece obtained from such a die;
 the dimensions of the test pieces machined from sintered and powder forged materials.
This International Standard is applicable to all sintered metals and alloys, excluding hardmetals.
2 Pressed and sintered test pieces for fatigue test by reverse bend and axial testing
2.1 General
The pressed and sintered piece may also be subjected to further treatment, such as sizing, polishing or heat
treatment. If such treatments are applied, they shall be stated in the test report. In a metallographically examined
cross section of a test piece, in
