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 considered. The arched gap on the wheels can be imaged as a continuous smooth surface 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 The radius of the arc of the circle closest to the component. 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 For both sides of a vehicle, the two planes parallel to the Y plane of the vehicle and tangent to 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; ---side turn signals, outline marker lamps, front and rear (side) position lights and parking lights; ---components installed on the front / rear bumper of the vehicle; following components located on the external surface of the vehicle are applicable to this document. ---components not higher than 2 m above the ground; ---components not lower than the floor line; ---components that can be touched by a sphere with a diameter of 100 mm. 4.3 There shall be no outward-facing sharp components on the external surface of a vehicle, as well as outward-facing protrusions that may increase the risk of scratches or bumps, or aggravate the injuries of the person being hit due to their shapes, dimensions, orientation and hardness, etc. in a collision accident. 4.4 There shall be no outward-facing components on the external surface of a vehicle that may scratch pedestrians, cyclists or motorcyclists. 4.5 The radius of curvature of protruding components on the external surface of a vehicle shall not be less than 2.5 mm.
