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.
Who is ISO 19380 - Centre of gravity measurements of vehicles and buses for?
ISO 19380 on heavy commercial vehicles and buses is useful for:
- Manufacturers of trucks and buses
- Manufacturers of road vehicle’s axle and tilt-table
- Mechanical engineers
Why should you use ISO 19380 - Centre of gravity measurements of vehicles and buses?
The centre of gravity position of the heavy commercial vehicles is vital for the driving condition, to ensure driving safety and handling stability. The longitudinal and lateral centre of gravity coordinates are determined in ISO 19380.
ISO 19380 navigates you through the measurements of the variables for the location of coordinates of the centre of gravity in the horizontal plane.
The measurements are carried out through test methods such as axle lift method, tilt-table method and stable pendulum method.
The typical operating ranges of the variables can be determined by ISO 19380.
ISO 19380 provides guidance regarding the determination of the centre of gravity in the horizontal plane and the centre of gravity height in the vertical plane.
Moreover, with ISO 19380 you could gain insights on how to construct a fit-for-purpose gravity vehicle to increase braking accuracy and ensure vehicle stability and safety by calculating the mass of the vehicle.
