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 4141-1 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 4141-1:1998), 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: Articulation test method and requirements for coiled cable assemblies

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 6722 and the following apply.
3.1
basic performance
〈cable〉 meeting basic requirements for general automotive applications
3.2
screen
conductive material intended to reduce the penetration and/or radiation of a varying electromagnetic field into
an assigned region
3.3
unscreened
absence of a screen
3.4
core
an assembly comprising a conductor with its own insulation (and screens, if there are any)
4 General
Single core identification shall conform to ISO 4141-3. The single components of multi-core sheathed cables
shall comply with ISO 6722 for single cores, and with ISO/PAS 16553 for data cables, with the exception of
the capacitance test of unscreened twisted pair cores for which 6.3 shall apply.
The general test conditions and the ovens used shall be in accordance with ISO 6722.
If a visual examination is required, the sheath shall be smooth, even and free from surface imperfections, e.g.
lumps, voids and particles.
The test sequence for each sample group shall be in accordance with Table 1. (Sequences are indicated with
an “X”, ordered from top to bottom.)
