この概要は現在英語のみで提供しています。

適用範囲

This standard applies to M1 category vehicles, N1 category vehicles with a maximum design total mass not exceeding 2500kg, and multipurpose goods vehicles. It is mandatory for all specified vehicle types entering the Chinese market. The standard specifically regulates the protection of front-row outboard seat occupants during frontal collisions.

技術要求

The standard specifies comprehensive performance criteria for occupant protection. It mandates specific limits for the Head Performance Criterion (HPC), Neck Injury Criterion (NIC), and Thoracic Compression Criterion (ThCC). Manufacturers must ensure these injury metrics remain within strict thresholds during impact. Additionally, the standard regulates the Femur Force Criterion (FFC) and the chest viscous criterion. General safety requirements include strict regulations on door locking systems, mandating that doors must not open during the collision, and front door latches must not engage. Post-crash occupant evacuation capabilities are also strictly evaluated. Furthermore, the standard outlines requirements for fuel system integrity, prohibiting continuous leakage exceeding specified rates post-impact. The standard also introduces specific requirements for airbag warning labels. Vehicles equipped with frontal airbags must display durable warning information regarding the extreme dangers of using rear-facing child restraint systems on seats protected by active airbags. Compliance with these labeling and warning requirements is mandatory.

試験方法

The primary evaluation involves a full-scale frontal impact test where the vehicle is propelled into a fixed, reinforced concrete barrier at a speed of 50 km/h. The test utilizes 50th percentile Hybrid III dummies positioned in the front outboard seats. Measurements are recorded using specialized data channels to assess head, neck, chest, and femur injuries. The standard also details a sled test procedure (Appendix E) as an alternative simplified test for vehicle type modifications.
