Road vehicles — Three-dimensional reference system and fiducial marks — Definitions
Defines a reference system and fiducial marks which are used to define dimensional data relating to road vehicles defined in ISO 3833, excepting motorcycles and mopeds. A figure illustrates the three-dimensional reference system showing the supporting surface, a schematic passenger car, the zero Z plane (horizontal zero plane), the zero Y plane (vertical longitudinal zero plane), and the zero X plane (vertical transverse zero plane).
Véhicules routiers — Système de référence tridimensionnel et points repères — Définitions
La présente Norme internationale établit un système de référence tridimensionnel et des points repères utilisés pour définir les dimensions des véhicules routiers définis dans l'ISO 3833, à l'exception des motocycles et cyclomoteurs.

Overview
ISO 4130:1978 specifies a standardized three-dimensional reference system and fiducial marks for road vehicles, with definitions tailored to dimensional data. Developed by the International Organization for Standardization (ISO), this standard serves as a foundational guideline for referencing and measuring vehicle dimensions, supporting a harmonized approach throughout the automotive industry. The standard specifically applies to road vehicles as defined in ISO 3833, but excludes motorcycles and mopeds. By clarifying key geometric reference planes and fiducial points, ISO 4130:1978 enhances consistency in vehicle measurement and data communication.
Key Topics
Three-dimensional reference system:
ISO 4130:1978 sets out three mutually orthogonal planes established during a vehicle’s initial design:- Zero Y plane: The vehicle’s longitudinal median, acting as a central vertical reference.
- Zero X plane: A vertical plane perpendicular to the Zero Y plane, typically oriented transversely.
- Zero Z plane: A horizontal plane normal to both the Zero X and Zero Y planes, corresponding broadly to the vehicle’s floor or supporting surface.
Fiducial marks:
The standard defines fiducial marks as three or more specific, manufacturer-established points (such as holes, surfaces, marks, or indentations) on the vehicle body. These are dimensioned relative to the three-dimensional reference system and are critical for:- Identifying exact measurement locations.
- Defining the vehicle’s position relative to the supporting surface under various loading conditions.
Dimensional conventions:
- Points are described using X, Y, and Z coordinates based on the reference planes.
- Dimensions may be positive or negative, depending on their relation to the defined zero planes.
- Reference planes can be situated outside the actual vehicle profile as needed.
Applications
ISO 4130:1978 is essential for a variety of practical applications in the automotive sector, including:
Automotive design and engineering:
Provides a universal framework for ensuring that vehicle dimensions are referenced and measured with consistency, regardless of manufacturer or region.Vehicle manufacturing and assembly:
Enhances accuracy in body alignment, component placement, and overall assembly quality through the definition of standardized measurement points.Quality control and inspection:
Supports uniform inspection standards by clarifying how and where measurements should be taken on all compliant vehicles.Technical documentation and communication:
Ensures all dimensional data is consistently referenced, aiding clear communication among automotive engineers, manufacturers, regulatory bodies, and suppliers.Vehicle regulations and compliance:
Facilitates alignment with international automotive standards and regulations by basing dimensional validation on a well-defined reference system.
Related Standards
ISO 4130:1978 is part of a broader suite of vehicle standards. Key related documents include:
ISO 3833:
Road vehicles - Types - Terms and definitions. Establishes general terminology for road vehicle types referenced in ISO 4130.ISO 612:
Road vehicles - Dimensions of motor vehicles and towed vehicles - Terms and definitions. Provides definitions specific to vehicle dimensions, underpinning the reference planes described in ISO 4130.
Implementing ISO 4130:1978 ensures standardized vehicle dimensional references and supports seamless integration with other international standards. Aligning with this standard is crucial for organizations involved in vehicle design, manufacturing, compliance, and automotive quality assurance.

FOREWORD
ISO (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, ßoad vehicles, and was circulated to the member bodies in July 1977.
