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.

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.

GB 14166 Safety belts and restraint systems for adult occupants of motor vehicles GB 14167 Safety-belt anchorages for vehicles ISO 209 Wrought aluminium and aluminium alloys 3 Terms and definitions The following terms and definitions are applicable to this Standard. 3.1 Protective system It refers to the interior fittings and devices intended to restrain the occupants 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. 4.2.2.2 The neck injury criteria (NIC) shall not exceed the values shown in Figures 1 and 2. 4.2.2.3 The neck bending moment about the Y axis shall not exceed 57N·m in the direction of extension. 4.2.2.4 The thorax compression criterion (ThCC) shall not exceed 50mm. 4.2.2.5 The viscous criterion (V·C) for the thorax shall not exceed 1.0 m/s. 4.2.2.6 The femur force criterion (FFC) shall not exceed the force-time performance criterion shown in Figure 3. 4.2.2.7 The tibia compression force criterion (TCFC) shall not exceed 8kN. 4.2.2.8 The tibia index (TI), measured at the top and bottom of each tibia, shall not exceed 1.3 at either location. 6.1.3.1 The orientation of the barrier is such that the first contact of the vehicle with the barrier is on the steering-column side. Where there is a choice between carrying out the test with a right-hand or left-hand drive vehicle, the test shall be carried out with the less favorable hand of drive as determined by the authority responsible for the tests. 6.1.3.2 The vehicle shall overlap the barrier face by 40% of the vehicle width ± 20mm. 6.1.4 State of vehicle 6.1.4.1 General requirements The test vehicle shall be representative of the series production, shall include all the equipment normally fitted and shall be in normal running order.
