Compliance overview
Scope and applicability
This standard applies to special school buses designed and manufactured specifically for transporting children aged 3 and above in kindergarten and students in the nine-year compulsory education system. It covers light-duty (length >5m and ≤6m) and large/medium-duty (length >6m and ≤12m) special school buses, categorized into buses for infants, primary school students, and primary/junior middle school students. It does not apply to articulated buses or double-decker buses.
Technical requirements
The standard specifies comprehensive safety and technical requirements across several key areas. It mandates specific structural dimensions and appearance markings, requiring a front collision safety structure and prohibiting exterior luggage racks. The standard sets power performance criteria, requiring a minimum specific power output, and establishes maximum passenger capacities based on the target age group. For vehicle systems, it mandates power steering, Anti-lock Braking Systems (ABS), disc brakes on front wheels, and speed limiting devices capping the maximum speed at 80 km/h. The standard also details requirements for the drivetrain, running gear (requiring tubeless radial tires), and bumpers. Manufacturers must ensure a minimum rollover stability angle under specified loading conditions. Regarding body structure and interior layout, the standard defines requirements for body skeleton structures, top structure strength, and upper structure strength to ensure passenger survival space during rollovers. It specifies the types, locations, and dimensions of exits (including passenger doors and emergency exits), and mandates specific dimensions for seats, seat spacing, and passenger space to accommodate children safely. The standard also requires the installation of seatbelts for all occupants and restraint partitions in front of seats. Additional safety features include fire prevention and control measures, such as flame-retardant materials, automatic fire extinguishing systems in the engine compartment, and emergency power switches. It also mandates driver visibility enhancements, interior air quality standards, driving recording systems with GPS and video monitoring, and specific signal systems like stopping signal plates and school bus marker lights.
Testing methods
The standard outlines several key testing methods to verify compliance. The Top Structure Strength Test (Appendix A) involves applying a vertical load of 1.5 times the vehicle's kerb mass to the roof to ensure structural integrity and passenger space are maintained. The Rollover Stability Test is conducted according to GB/T 14172 to measure the stable tilt angle under both loaded and unloaded conditions. The Driver Visibility Test (Appendix C) uses a specific arrangement of cylindrical test objects around the vehicle to ensure the driver has unobstructed views of critical areas. Other tests include verifying the strength of seats and their anchorages as per GB 24406 and GB 13057, and assessing the flammability of interior materials according to GB 8410-2006.
FAQs
What products are regulated under GB 24407-2012?
GB 24407-2012 regulates special school buses designed for transporting children aged 3 and above in kindergarten and students in the nine-year compulsory education system. This includes light-duty and large/medium-duty buses categorized for infants, primary school students, and primary/junior middle school students.
Are there any updates from the previous version of GB 24407-2012?
Yes, GB 24407-2012 replaced GB 24407-2009. Key updates include expanding the scope to cover kindergarten and junior middle school students, adding requirements for power performance, steering, braking, and transmission systems, and introducing more detailed specifications for body structure, exits, seats, and fire safety. A modification sheet was also issued in 2017 with further adjustments to seat dimensions and safety equipment requirements.
Does GB 24407-2012 reference international standards?
The standard primarily references other Chinese national standards (GB series) for testing methods and component requirements, such as GB 13094 for bus structure safety and GB 8410 for interior material flammability. It does not directly adopt specific international standards like ISO, but its technical requirements are aligned with global school bus safety principles.
