180 (the International Organization for Standardization) is a worldwide federation
‘of national standards institutes (ISO member bodies). The work of developing
International Standards is carried out through ISO technical committees. Every
member body interested in a subject for which a technical committee has been set
up 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,
Draft International Standards adopted by the technical committees are circulated
to the member bodies for approval before their acceptance as International
‘Standards by the ISO Council
International Standard ISO 4130 was developed by Technical Committee
ISO/TC 22, Road vehicles, and was circulated to the member bodies in July 1977.
Ithas been approved by the member bodies of the following countries
Australia ttaty Spain
Austria Japan Sweden
Belgium Korea, Dem. P. Rep. of Switzerland
Brazil Korea, Rep. of Turkey
Bulgaria Mexico United Kingdom
Chile Netherlands USA.

Road vehicles — Three-dimensional reference system and
fiducial marks — Definitions
1 SCOPE AND FIELD OF APPLICATION
‘This International Standard defines a three-dimensional reference system and fiducial marks which are used to define
dimensional data relating to road vehicles defined in ISO 3833, excepting motorcycles and mopeds.
2. REFERENCES

3. DEFINITIONS
No. Term Definition Symbol
3.1 | Three-dimensionat | Three orthogonal planes established by the vehicle manufactur X,Y,Z
reference system | initial design stage (see figure)
3.1.1 | Zero Y plane ‘The longitudinal median plane (of the vehicle), as defined in ISO 612. Y
3.1.2 | Zero X plane A plane, conventionally vertical, normal to the zero Y plane (3.1.1) x
3.1.3. | ZeroZ plane A plane, conventionally horizontal, normal to the zero X and Y planes z
(3.1.2 and 3.1.1)
Notes
1 With the exception of cimeasions related to the supporting surtace (ground), each
point on the vehicle defined in the thres-dimensiona reference system by its three
ordinates X,Y and 2,
2. Distances forward ofthe zero X plane (3.1.21, tothe let of the er0 Yplane (3.1.1), |
‘and below the zero Z plane (3.13) ae rgarded & negative dimensions, |
3 The planes defined in 31,2 and 3.1.3 mey be located outside the vehicle profile
3.2 | Fidueial marks ‘Three or more physical points (holes, surfaces, marks or indentations), on the
vehicle body, as defined by the manufacturer.
NOTE — Thete points are dimensioned in roltion tothe three-dimensional ref
system (3.1). They ae also used to define the position of the vehicle relative tothe
‘upporting surface (ground in various loading conditions.
