NOTE. it includes front hood, luggage compartment lid, doors, fenders, roof, lighting and light
signaling devices, and visible reinforcing ribs, etc.
3.3 floor line
The geometric trajectory formed by the contact point using a cone with a half angle of 30 and
continuous contact along the lowest position where the external surface of a laden vehicle can
be touched.
NOTE 1.independently determine the height of the cone; based on the principle of ease of
operation, the cone top is upward, and the cone axis is perpendicular to the horizontal
plane.
NOTE 2.when determining the floor line, the lifting points, exhaust pipes or wheels are not

formed after filling. When determining the floor line at both ends of the vehicle, the
bumper needs to be considered. For a specific vehicle type, the cone contact point may
be at the end of the bumper or on a vehicle body panel underneath the bumper. If there
are two or more contact points at the same time, take the downmost contact point to
determine the floor line.
3.4 radius of curvature

3.5 laden vehicle
A vehicle loaded to the maximum allowable total mass.
NOTE. if the vehicle is equipped with a hydropneumatics, hydraulic or air suspension device, or
an automatic stabilizing device that changes with the load, load it in accordance with the
most unfavorable conditions specified by the manufacturer under normal driving
conditions.
3.6 extreme outer edge

the outmost edges of both sides of the vehicle; for the front / rear end of a vehicle, a vertical
transverse plane parallel to the X plane of the vehicle and tangent to the front / rear outmost
edges of the vehicle.
NOTE. when determining the extreme outer edge of the vehicle, the following protrusions are not
considered.
---the part where the tire is in contact with the ground and the tire valve;
---anti-skid device mounted on wheels;
---indirect vision device;
