to the longitudinal plane of the vehicle. The trailing edge may not require the
installation of a continuous vertical component.
5.7 The upper edge of the lateral protection device shall be no larger than 350

increase the total width of vehicle. The outer surface of the main part of the
vehicle is located in the outermost edge (maximum width) within the position of
not more than 150 mm.
6.2 The outer surface of lateral protection device shall be smooth and as
continuous as possible before and after. Adjacent parts are allowed to overlap.
But lapped exposed edges shall be backward or downward.
6.3 The lateral protection device may be a continuous plane or consist of one
or more crossbars or be a combination of plane and crossbar.
6.4 The structural requirements for lateral protection device are as follows.
6.8 In the no-load state of the vehicle, the ground clearance at any point on
the lower edge of the lateral protection device shall not be more than 550 mm.
6.9 The upper edge of the lateral protection device shall be no larger than 350
mm from the vehicle component on the upper side. This component means a
part that is delivered or in contact with a vertical plane cut at the outer side of
the tire (excluding the part of the tire that is in contact with the ground), except
the followings.
6.10 The lateral protection device shall have a certain rigidity, fixed firmly (the
loosing is not because of vibration). Except the parts described in 4.5, it shall
be made of metal or other appropriate material. When a static pressure of 1 kN
is applied to a circular pressure head of 220mm ± 10mm in diameter
perpendicularly to each part of the outer surface of the device, the deformation
due to the force shall meet the following requirements.
6.11 The various facilities that are permanently mounted in the vehicle such
as spare tire, battery rack, gas cylinder, fuel tank, lamp, reflector, tool box, etc.

vehicle.
9.5 The rear underrun protection device may be designed with different
mounting positions at the rear of the vehicle. At this moment, there shall be a
reliable way to ensure that it shall not be freely moved in the mounting position
after it is mounted. When adjusting its mounting position, it needs to exert a
force not greater than 400 N.
9.6 The rear underrun protection device at operation position shall be
connected with vehicle frame or other similar components. The rear underrun
protection device shall have adequate barrier to rear-end collisions in a
direction parallel to the longitudinal axis of the vehicle to prevent a collision.
