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 Internationa! Standards by the ISO Councit. was developed by Technical International Standard ISO 4130 Committee 1SO/TC:22, Road vehicles, and was circulated to the member bodies in July 1977. It has been approved by the member bodies of the following countries : Italy Australtia Spain Austria Japan Sweden Belgium Korea, Dem. P. Rep. of Switzerland Brazil Korea, Rep. of Turkey Bulgaria Mexico United Kingdom Chile Netherlands U.S.A. Czechoslovakia U.S.S.R.

ISO 3833, Road vehicles - Types - Terms and definitions. 3 DEFINITIONS No. Term Symbol Definition 3.1 Three-dimensional Three orthogonal planes established by the vehicle manufacturer in the X,Y,Z initial design stage (see figure). reference system The longitudinal median plane (of the vehicle), as defined in 1SO 612. 3.1.1 Zero Y plane Y 3.1.2 Zero X plane A plane, conventionally vertical, normal to the zero Y plane (3.1.1). x 3.1.3 Zero Z 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 dimensions related to the supporting surface (ground), each point on the vehicle is defined in the three-dimensional reference system by its three coordinates : X, Y and Z. 2 Distances forward of the zero X plane (3.1.2), to the left of the zero Y plane (3.1.1) and below the zero Z plane (3.1.3) are regarded as negative dimensions. 3 The planes defined in 3.1.2 and 3.1.3 may be located outside the vehicle profile. 3.2 Fiducial marks Three or more physical points (holes, surfaces, marks or indentations), on the vehicle body, as defined by the manufacturer. NOTE -- These points are dimensioned in relation to the three-dimensional reference system (3.1). They are also used to define the position of the vehicle relative to the supporting surface (ground) in various loading conditions. ternational Organization for Standardization Copyright In ted without license from IHS Not for Resale
