Compliance overview
Scope and applicability
This standard applies to the design, manufacture, and inspection of tri-wheel vehicles. It is mandatory for manufacturers producing these specific agricultural and commercial vehicles for the Chinese market. It does not apply to low-speed goods vehicles, as those requirements have been removed in this version. The standard integrates previous safety sign requirements, referencing GB 24943-2010.
Technical requirements
This standard specifies general vehicle and driver workspace requirements, including structural integrity, power-to-weight ratio, and mass utilization coefficients. For the driver's position, it mandates dimensions for cab space, seating, and steering wheel placement to prevent operational hazards. The standard outlines criteria for steering systems, braking performance (both hydraulic and pneumatic), and transmission components. Manufacturers must ensure vehicles meet strict stability limits, including side-tilt angles and steering axle load ratios. It also prohibits the use of overdrive transmissions and requires specific speed limitation devices. It covers lighting and signaling devices, rearview mirrors, and thermal protection. The standard sets definitive limits for noise levels, exhaust emissions (referencing GB 20891), and fuel consumption. All vehicles must be equipped with appropriate safety signs and warning devices as specified in the normative appendices.
Testing methods
The standard details evaluation procedures including dimensional measurements, braking performance road tests, and pneumatic response time testing (per Appendix B). It references various testing standards such as GB/T 23931-2021 for steering force and GB/T 19120 for braking systems. Visual inspections and durability tests for safety signs are also mandated.
FAQs
What products are regulated under GB 18320-2025?
It regulates tri-wheel vehicles, which are cargo vehicles with three wheels and a maximum design speed of 50 km/h or less.
Are there any updates from the previous version of GB 18320-2025?
