Compliance overview
Scope and applicability
This standard specifies the classification, appearance, dimensions, technical requirements, and testing methods for vehicle markings of dangerous goods in road transportation. It applies to the production and use of these markings for vehicles transporting dangerous goods in China. This standard is mandatory for all manufacturers and operators involved in the road transportation of dangerous goods. It explicitly excludes markings for vehicles transporting radioactive materials. The standard covers three main types of markings: rectangular plates, diamond-shaped plates, and special plates (for environmentally hazardous and elevated temperature substances).
Technical requirements
GB 13392-2023 outlines comprehensive technical specifications for dangerous goods vehicle markings. The standard defines the material requirements, stating that rectangular plate base materials must use steel plates with a melting point above 900°C or materials that maintain information display after 15 minutes of fire exposure. All markings must use Class I or higher retroreflective sheeting conforming to GB/T 18833-2012. The standard specifies detailed requirements for appearance quality, ensuring plates are flat, smooth, and free of defects. It mandates specific performance criteria including photometric performance (retroreflection coefficients), chromatic performance (color coordinates), and impact resistance. Additionally, the markings must withstand various environmental conditions. This includes resistance to solvents (gasoline and ethanol), salt spray corrosion, high and low temperatures (-40°C to 70°C), and weathering via xenon arc lamp exposure. The standard also sets requirements for adhesion performance of the retroreflective sheeting and fire resistance for rectangular plates.
Testing methods
The standard prescribes specific testing procedures to verify compliance. Tests include visual inspection under daylight conditions (>150 lx) and dimensional measurements. Photometric and chromatic performance are tested according to GB/T 18833. Impact resistance is evaluated using a steel ball drop test at low temperatures for rectangular plates and a specific drop height for diamond/special plates. Environmental resistance tests involve immersing samples in solvents, exposing them to a salt spray chamber for 120 hours, and subjecting them to thermal cycling. Weathering tests utilize a xenon arc lamp with specific irradiance and water spray cycles. Adhesion is measured by peeling the retroreflective film, and fire resistance is tested by exposing the plate to a 900°C flame for 15 minutes.
FAQs
What products are regulated under GB 13392-2023?
GB 13392-2023 regulates vehicle markings used for the road transportation of dangerous goods in China. This includes rectangular plates displaying hazard identification numbers and UN numbers, diamond-shaped plates indicating hazard classes, and special plates for environmentally hazardous or elevated temperature substances.
Are there any updates from the previous version of GB 13392?
Yes, GB 13392-2023 replaces GB 13392-2005. Key updates include the addition of terms and definitions, new requirements for rectangular and special plate dimensions, updated technical requirements for photometric and chromatic performance, and the introduction of hazard identification numbers (Appendix A). It also removes requirements for marking lights.
Does GB 13392-2023 apply to international transport?
For international road transport, diamond-shaped plates without Chinese text may be used. If markings on containers or portable tanks already comply with the International Maritime Dangerous Goods Code or Technical Instructions for the Safe Transport of Dangerous Goods by Air, they are considered to meet the relevant requirements of this standard for domestic road transport segments.
