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.
ISO 14323 was prepared by the International Institute of Welding, recognized as an international
standardizing body in the field of welding in accordance with Council Resolution 42/1999.

Resistance spot welding and projection welds — Destructive
testing of welds — Specimen dimensions and procedure for
impact shear test and cross-tension testing
1 Scope
This International Standard covers destructive testing of welds.
This International Standard specifies specimen dimensions and testing procedures for impact shear and
cross-tension testing of resistance spot and embossed projection welds in overlapping sheets, in any metallic
material of thickness 0,5 mm to 4 mm.
2 Normative references
The following referenced documents are indispensable for the application 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.
ISO 669, Resistance welding — Resistance welding equipment — Mechanical and electrical requirements
ISO 14272, Specimen dimensions and procedure for cross tension testing resistance spot and embossed
projection welds
ISO 14329, Resistance welding — Destructive tests of welds — Failure types and geometric measurements
for resistance spot, seam and projection welds
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 669 and ISO 14329 and the
following apply.
3.1
corona bond
area of the weld at the faying surfaces in which solid-phase bonding has occurred
3.2
impact cross-tension failure energy
failure energy measured in the impact cross-tension test
3.3
