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 4141-4 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical
and electronic equipment.
This second edition cancels and replaces the first edition (ISO 4141-4:2001), which has been technically
revised.
ISO 4141 consists of the following parts, under the general title Road vehicles — Multi-core connecting
cables:
⎯ Part 1: Test methods and requirements for basic performance sheathed cables
⎯ Part 2: Test methods and requirements for high performance sheathed cables
⎯ Part 3: Construction, dimensions and marking of unscreened sheathed low-voltage cables
⎯ Part 4: Test methods and requirements for coiled cable assemblies

3 Preconditioning
This test shall be performed in accordance with ISO 4141-3 on coiled cables assembled with appropriate
connectors in accordance with ISO 1185, ISO 1724, ISO 3731, ISO 3732, ISO 7638-1, ISO 7638-2,
ISO 11446, ISO 12098 or ISO 25981, along with their anti-kink protection (if any).
The following preconditioning shall be performed prior to testing:
a) conditioning for 2 h at a temperature of (− 40 ± 2) °C, one extension once to its maximum admitted
extension length in accordance with ISO 4141-3 within 15 s after being removed from the temperature
chamber, and subsequently resting for 120 s in restored conditions at room temperature;
b) the same as in step a), but conditioning for 2 h at (80 ± 2) °C;
c) cooling down at room temperature for another 2 h.
4 Articulation test
4.1 Purpose
The purpose of the articulation test is to specify the strength of the complete plug and cable assembly and the
effect of anti-kink protection against bending, in order to replicate extreme angles occurring between vehicle
and trailer whilst manoeuvring.
4.2 Test method
Both plugs shall be inserted in sockets in a test arrangement in accordance with Figure 1. The fixing of at least
one socket shall permit rotation around axis A.
Conductor breakage shall be monitored by applying a current of (5 ± 0,5) A to all pins and connected
conductors of the coiled assembly during the entire test phase (see Figure B.2). Conductor breakage occurs if
the app
