Full title and description

ISO 10392:2011 — Road vehicles — Determination of centre of gravity. This International Standard specifies methods for determining the location of the centre of gravity (CG) of a road vehicle (as defined in ISO 3833), including a method for the CG coordinates in the horizontal plane and two methods for determining CG height above ground (axle lift and stable pendulum). The standard is available in PDF and paper formats from ISO.

Abstract

ISO 10392:2011 provides procedures to measure the vehicle centre of gravity: it gives a horizontal-plane coordinate method and two methods to determine CG height (axle lift and stable pendulum). The axle lift method is simpler and typically yields accuracy of a few percent; the stable pendulum method can achieve accuracy on the order of 0.5%. The standard is intended for use where an accurate vehicle CG location and height are required for testing, design and safety assessment.

Scope

Specifies methods for determining the location of the centre of gravity of a road vehicle defined by ISO 3833. It includes: a method to determine CG coordinates in the horizontal plane, and two alternative methods to determine CG height above ground (axle lift and stable pendulum). The standard applies to road vehicles for which an accurate CG determination is required for design, testing, stability analysis or regulatory purposes.

Key topics and requirements

• Definition and reference to vehicle terminology as given in ISO 3833 (terms and vehicle definitions).
• Procedure to determine CG coordinates in the horizontal plane.
• Axle lift method for CG height — lower equipment needs, typical accuracy in the range of a few percent.
• Stable pendulum method for CG height — higher precision, accuracy reported around 0.5% when correctly executed.
• Requirements for test setup, measurements and basic calculations to locate CG and express coordinates relative to vehicle reference points.

These key topics and accuracy guidance are summarized from the ISO abstract and method descriptions.

Typical use and users

Used by vehicle manufacturers, test laboratories, certification bodies, automotive engineering teams (vehicle dynamics/stability), safety engineers and research organizations. Typical applications include vehicle design validation, rollover and stability assessment, regulatory compliance testing, and forensic or accident investigations where accurate CG data are needed.
