Escopo e aplicabilidade

This standard applies to M1 category and N1 category vehicles, as well as multipurpose goods vehicles. It is mandatory for manufacturers producing these vehicle types for the Chinese market. The standard does not apply to vehicles outside these specified categories.

Requisitos técnicos

This standard specifies the technical requirements for occupant protection during a lateral collision, focusing on the structural integrity of the passenger compartment and the safety of the occupants. It outlines the performance criteria for side-impact dummies, specifically the WorldSID 50th and EuroSID-2re models, evaluating head, shoulder, chest, abdomen, and pelvic injury metrics. Additionally, the standard mandates strict body safety requirements to prevent doors from opening during a crash and ensures that occupants can be safely extracted post-collision. Manufacturers must ensure no sharp edges or dangerous protrusions are created by interior component detachment. For electric and hybrid vehicles, the standard introduces specific electrical safety requirements. These vehicles must comply with protection against electric shock, electrolyte leakage limits, and REESS safety requirements as specified in GB/T 31498-2021.

Métodos de ensaio

The testing methodology involves a mobile deformable barrier impacting the stationary test vehicle at a specified speed. The evaluation includes: - Side-impact dummy placement and measurement using specific channels for head, shoulder, chest, abdomen, and pelvic forces. - Post-crash evaluation of door latch integrity and static pull tests. - Assessment of fuel leakage rates and fire risks. - Verification of electrical safety for high-voltage systems.
