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 2.
The main task of technical committees is to prepare International Standards. 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.
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.
International Standard ISO 14324 was prepared in collaboration with the International Institute of Welding
which has been approved by the ISO Council as an international standardizing body in the field of welding.

INTERNATIONAL STANDARD ISO 14324:2003(E)

Resistance spot welding — Destructive tests of welds —
Method for the fatigue testing of spot welded joints
1 Scope
This International Standard specifies test specimens and procedures for fatigue testing spot welds, at ambient
conditions, under repeated tensile loading to produce either shear or cross-tension loading of the spot weld, in
steel of sheet thicknesses of 0,5 mm to 6 mm. The test results are not, in general, directly applicable to the
fatigue behaviour of a spot-welded component or structure. This procedure can be used for other materials
provided proper test conditions (e.g., heating) have been determined.
