Foreword
The technical content of this Standard is modified using ECE R94 Uniform
provisions concerning the approval of vehicles with regard to the protection of
the occupants in the event of a frontal collision (Version 01, 2003). The main
differences and reasons between this Standard and ECE R94 are as follows.
a) In the seat section, REFER to the contents of paragraph 5.1.4.3.11.1 in GB
11551-2003 The protection of the occupant in the event of a frontal collision
for passenger car; SUPPLEMENT the corresponding adjustment methods
in this Standard, which is mainly due to the consideration of human body
parameters and model characteristics in China.
b) Due to the formal differences between the standard system and the
regulatory system, this Standard incorporates the content of Annex 3 in
ECE R94 into the standard text, and deletes the contents of the relevant
certification marks in Annex 1 and Annex 2 of ECE R94. The Annex A,
Annex B, Annex C, Annex D, Annex E, Annex F, and Annex G of this
Standard correspond to Annex 4, Annex 5, Annex 6, Annex 8, Annex 9,
Annex 10, and Annex 7 of ECE R94, respectively.
c) Due to the compliance with China’s standard systems, this Standard
deletes the contents of relevant certification management procedures in
Clause 3, Clause 4, Clause 8, Clause 9, Clause 10, Clause 11, and Clause
12 of ECE R94.
The Annex A, Annex B, Annex C, Annex D, Annex E, Annex F, and Annex G of
this Standard are normative annexes. The Annex H is an informative annex.
This Standard was proposed by the National Development and Reform
Commission.
This Standard shall be under the jurisdiction of National Technical Committee
for Standardization of Automobiles.

The protection of the occupants in the event of
an off-set frontal collision for passenger car
1 Scope
This Standard specifies the technical requirements and test methods for the
protection of the occupants in the front outboard seats in the event of an off-set
frontal collision for passenger car.
This Standard is applicable to the Class M1 vehicles with a maximum design
total mass of 2 500kg or less. For Class M1 vehicles of which the mass exceeds
this range and other types of vehicles, it can be referred to for implementation.
2 Normative references
The provisions in the following documents become the provisions of this
Standard through reference in this Standard. For dated references, the
subsequent amendments (excluding corrections) or revisions do not apply to
this Standard. However, parties who reach an agreement based on this
Standard are encouraged to study if the latest editions of these documents are
applicable. For undated references, the latest editions apply to this Standard.

and contribute towards ensuring compliance with the requirements set out in
Clause 4.
3.2 Type of protective system
3.14 Rearward-facing
It means facing in the direction opposite to the normal direction of travel of the
vehicle.
4 Requirements
4.1 General requirements
4.1.1 The “H” point for each seat shall be determined in accordance with the
procedure described in Annex C.
4.1.2 When the protective system for the front seating positions includes belts,
the belt components shall meet the requirements of GB 14166.
4.1.3 Seating positions where a dummy is installed and the protective system
includes belts, shall be provided with anchorage points conforming to GB 14167.
4.2 Technical requirements
4.2.1 The test of the vehicle carried out in accordance with the method
described in Clause 6 of this Standard shall be considered satisfactory if the
following requirements are all met at the same time.
4.2.2 The performance criteria determined, in accordance with Annex D, on
the dummies in the front outboard seats shall meet the following requirements.
4.2.2.1 The head performance criterion (HPC) shall not exceed 1 000. The
resultant head acceleration shall not exceed 80g for more than 3ms. However,
it excludes rebound movement of the head.
