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 18594 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 6, Resistance welding.
Requests for official interpretations of any aspect of this International Standard should be directed to the
Secretariat of ISO/TC 44/SC 6 via your national standards body. A complete listing of these bodies can be
found at www.iso.org.

INTERNATIONAL STANDARD ISO 18594:2007(E)
Resistance spot-, projection- and seam-welding — Method for
determining the transition resistance on aluminium and steel
material
1 Scope
This International Standard specifies the procedure and the experimental set-up for determining the transition
resistance of a single sheet or two overlapping sheets of aluminium or steel, with or without surface treatment,
and with or without surface coating.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
contact resistance
electric property of a contact area between two bodies which opposes and limits the passage through it of a
steady current
EXAMPLE The contacts between electrode/electrode, electrode/sheet and sheet/sheet.
2.2
bulk resistance
ohmic resistance of an electrical conductor
2.3
total resistance
R
electrical resistance as measured between the sensing clamps (includes both bulk and contact resistances)
See Figure 1 and Figure 2.
2.4
set-up resistance
R
s
resistance of the experimental set-up between the sensing clamps without metal sheet(s) between the
electrodes, the two electrodes being in direct contact
See Figure 2 b), (R +R +R ).
0 1 7
2.5
transition resistance
R
t
total resistance minus the set-up resistance
