This document describes a standard method for measuring a vehicle’s longitudinal and lateral
(horizontal plane) centre of gravity (CG) positions and three methods for estimating a vehicle’s vertical
CG position, the axle lift, tilt-table, and stable pendulum methods. It applies to heavy vehicles, that
is commercial vehicles and buses as defined in ISO 3833 (trucks and trailers with maximum weight
above 3,5 tonnes and buses and articulated buses with maximum weight above 5 tonnes, according to
ECE and EC vehicle classification, categories M3, N2, N3, O3 and O4). CG measurements are performed
separately for each single unit.
