Compliance overview
Scope and applicability
This standard applies to the identification markers of school buses and their related facilities in China. It is specifically designed for manufacturers and operators of specialized school buses transporting preschool children and students. Compliance is mandatory for all school bus identification elements, including vehicle body markings and stop signs. It references GB 7258 for safety technical conditions.
Technical requirements
The standard specifies the composition and style of specialized school bus exterior markings, including the school bus logo, Chinese characters, passenger capacity, and vehicle numbering. Manufacturers must ensure the body base color and contour markings meet strict visual and material criteria. The contour markings must utilize fluorescent yellow-green reflective materials to enhance visibility. It details the requirements for school bus plates (carried inside the vehicle) and external stop signs (advance warning and stop point signs). The plates must contain specific vehicle and driver information, printed and sealed according to regulatory guidelines. External signs must comply with the color and reflective performance standards outlined in GB 5768. The standard mandates specific material properties for paints and reflective films, including chromaticity performance and coefficient of retroreflection. Identification elements must be replaced if information is illegible, colors fade significantly, or retroreflective coefficients drop by more than 50%. Material performance must align with GA 522 and GA 523 specifications.
Testing methods
The standard outlines evaluation procedures for visual and material properties. Color verification is conducted by comparing samples against standard color templates. Dimensional checks are performed using length measuring tools with 1mm precision. Material performance, including retroreflection coefficient and chromaticity, is tested using methods specified in GB/T 18833 and JT/T 693 to ensure long-term visibility and compliance.
