What is ISO 19380 - Centre of gravity measurements of vehicles and buses about?
ISO 19380 is an international standard on heavy commercial vehicles and buses that are presented for measuring the location of the centre of gravity of an individual vehicle unit in the horizontal, lateral and vertical planes.
ISO 19380 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.
NOTE: ISO 19380 applies to heavy vehicles, that is commercial vehicles and buses as defined in ISO 3833 (trucks and trailers with a maximum weight above 3,5 tonnes and buses and articulated buses with a 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.
