Compliance overview
Scope and applicability
This standard applies to the structural design, manufacturing, and technical characteristics of special school buses designed for organized transportation of preschool children over 3 years old or students in the compulsory education stage. It covers classifications such as light special school buses and large/medium special school buses, categorized by their intended use for infants, primary students, or primary and junior middle school students. This standard is mandatory for all manufacturers producing school buses for the Chinese market. It does not apply to articulated buses or double-decker buses.
Technical requirements
The standard outlines comprehensive safety requirements across various vehicle systems. It specifies criteria for exterior identification and structural dimensions, ensuring vehicles feature a collision-safe front structure and specific height limitations. Power and performance requirements mandate a minimum specific power output and the installation of speed limiting systems, capping the maximum speed at 80 km/h. Manufacturers must ensure all vehicles are equipped with advanced braking and driving systems. This includes mandatory Anti-lock Braking Systems (ABS), disc brakes on all wheels, and, for vehicles over 8 meters, auxiliary braking devices. The standard also introduces requirements for Automatic Emergency Braking Systems (AEBS) and tire blow-out emergency safety devices. Structural integrity and occupant protection are heavily emphasized. The standard defines requirements for body structure strength, including top structure strength and upper structure strength during rollover scenarios, ensuring sufficient survival space for passengers. It details specifications for exits, steps, aisles, and interior arrangements, mandating specific seat dimensions, seat spacing, and the installation of restraint partitions and safety belts for all occupants, including children and attendants. Vehicle designs must guarantee safe evacuation routes and adequate passenger free space. Fire prevention and control measures are rigorously specified to mitigate risks. The standard requires specific configurations for fuel systems, electrical equipment, and engine compartments, including the installation of automatic fire extinguishing systems in engine compartments. Interior materials must meet strict flame retardant requirements according to GB 38262, and specific fire extinguishing equipment must be configured as per GB 34655. Additionally, the standard mandates comprehensive driver visibility systems, including rearview cameras and specific direct/indirect vision requirements, alongside interior air quality standards and driving information recording systems.
Testing methods
The standard references several testing methodologies to verify compliance. Key tests include the Top Structure Strength Test (Appendix A), which applies a vertical load of 1.5 times the vehicle's kerb mass to the roof to ensure structural integrity. The Driver Visibility Test (Appendix C) uses specific cylindrical objects placed around the vehicle to evaluate the driver's direct field of view. Additionally, rollover stability is tested using a tilt table according to GB/T 14172, and seat strength is evaluated per GB 24406 and GB 13057.
