Compliance overview
Scope and applicability
This standard applies to N2, N3, O3, and O4 category vehicles, specifying the technical requirements for lateral and rear underrun protection devices. It is mandatory for all applicable manufacturers and does not apply to semi-trailer towing vehicles or special-purpose vehicles designed for transporting indivisible long goods. Refer to GB/T 15089 for vehicle classification details.
Technical requirements
The standard outlines comprehensive requirements for both lateral protection devices (LPD) and rear underrun protection devices (RUPD). For LPDs, it dictates structural dimensions, material stiffness, and specific positioning relative to the vehicle's wheels and chassis. Manufacturers must ensure the lower edge ground clearance does not exceed 550mm for lateral devices. For RUPDs, the standard specifies cross-section heights, width limitations, and maximum ground clearance limits. Special provisions are included for vehicles transporting liquid dangerous goods and those equipped with tail lifts, requiring specific deformation and energy absorption capabilities. Compliance with these structural and dimensional limits is critical for type approval.
Testing methods
The standard mandates rigorous evaluation procedures, including a static pressure test for LPDs using a circular flat indentor to measure deformation. For RUPDs, compliance can be verified through either a static loading test (applying forces at two or three specific points) or a moving barrier rear impact test to assess underrun prevention and energy absorption. Appendix D provides detailed specifications for the instrumentation and data channels used during these dynamic tests.
FAQs
What products are regulated under GB 11567-2017?
It regulates lateral and rear underrun protection devices installed on N2, N3, O3, and O4 category motor vehicles and trailers. These devices are mandatory to protect unprotected road users.
Are there specific requirements for liquid dangerous goods transport vehicles?
Yes, the standard includes enhanced requirements for road transport liquid dangerous goods tank vehicles, specifically limiting the maximum horizontal deformation of the rear underrun protection to 150mm. These vehicles must have the protection located at the very rear end.
What is the implementation timeline for GB 11567-2017?
For new type approval applications, the standard applies 1 year after the implementation date. For existing production models, compliance is required within 2 years.
