Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
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. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
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.
International Standard IS0 6722-2 was prepared by Technical Committee
ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical and electronic
equipment.
This third edition cancels and replaces the second edition
(IS0 6722-2: 1985), which has been extended to include performance re-
quirements of new test methods.
IS0 6722 consists of the following parts, under the general title Road ve-
hicles - Unscreened low-tension cables:
- Part 1: Test methods
- Par-t 2: Requirements
ca-
- Part 3: Conductor sizes and dimensions for thick-wall insulated
b/es
- Part 4: Conductor sizes and dimensions for thin-wall insulated cables
