3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
bumper beam
Structural device used to mitigate damage caused by frontal and rear impacts on the
vehicle.
Note: Usually installed at the ends of the left and right longitudinal beams of the vehicle.
3.2
protection system
Internally mounted components and devices used to restrain occupants.
3.3
vehicle width
Width of the vehicle measured at the fenders.
4 Requirements
4.1 Static requirements for bumper
4.1.1 Effective height of bumper beam
After completing the static tests for bumper in 5.2.1 ~ 5.2.3, the effective overlap
dimension of the bumper beam shall not be less than 75 mm; if the effective overlap
dimension of the bumper beam is less than 75 mm, the effective height of the bumper
beam shall not be less than 100 mm.
4.1.2 Effective width ratio of bumper beam
After completing the static tests for bumper in 5.2.4 ~ 5.2.6, the effective width ratio of
the bumper beam shall not be less than 70%.
4.2 Bumper dynamic and low-speed collision requirements
After the vehicle has completed the bumper dynamic test and low-speed collision test
specified in 5.3 and 5.4 respectively, it shall meet the following requirements:
a) The front and rear windscreens and the left and right door glasses shall be free
of damage;
b) The door shall open normally;
c) The vehicle's fuel supply system and cooling system shall be leak-free, and its
sealing devices and oil and water tank covers shall work properly; for hybrid
and battery electric vehicles, after the collision test, the vehicle's power high-
voltage system including the rechargeable electrical energy storage system
(REESS) and the high-voltage components connected to it shall comply with
the anti-electric shock protection requirements, electrolyte leakage requirements
and REESS requirements in GB/T 31498-2021;
d) The left and right longitudinal beams shall not be bent or crushed, and damage

The test area shall be large enough to accommodate the runway, barriers and technical
equipment necessary for the test. The runway at least 5 m in front of the barrier shall be
flat, dry and clean.
5.1.2 Test vehicle mass
5.1.2.1 The fuel tank (if any) shall be filled with fuel accounting for 90% ~ 95% of the
total capacity or with water accounting for 90% of the fuel mass when the fuel tank is
