Champ d’application

This standard applies to the design, manufacturing, and safety verification of tractors operating within China. It covers various tractor types, including wheeled tractors, tracklaying tractors, walking tractors (hand tractors), and belt-drive tractors. It is mandatory for all tractor manufacturers and importers targeting the Chinese agricultural machinery market. The standard does not apply to non-agricultural or specialized industrial vehicles not classified as tractors under GB/T 6960.

Exigences techniques

The standard specifies comprehensive safety requirements based on the principles of risk assessment and risk reduction. For wheeled and tracklaying tractors, it mandates strict limits on noise and vibration exposure to the operator. It outlines detailed braking performance criteria, including specific parking and service braking requirements for standard, mountain, and rubber-track tractors. Manufacturers must ensure strict adherence to these dynamic performance limits. Significant focus is placed on operator workstation safety. This includes precise dimensional requirements for access ladders, emergency exits, and minimum operational space to prevent crushing and shearing hazards. The standard also specifies requirements for operator seats, interior material burning rates, and field of vision. Compliance with these ergonomic and structural dimensions is critical for type approval. The standard requires robust protective structures, including Roll-Over Protective Structures (ROPS) and Falling Object Protective Structures (FOPS). It sets forth safety measures for power take-off (PTO) shafts, hydraulic systems, electrical equipment, and fuel systems to prevent mechanical and fire hazards. Notably, it includes new requirements for electronic control systems, covering automatic auxiliary driving and unmanned/remote control systems. These advanced systems must feature fail-safe mechanisms and automatic shutdown capabilities. For walking tractors, the standard specifies tailored requirements for braking, control operations, and protective guards for rotating parts. It mandates that rotary tillers must stop operating when the tractor is reversing, ensuring operator safety. Manufacturers must implement reliable interlocking mechanisms to meet this requirement.

Méthodes d’essai

The standard references various testing procedures to verify compliance. Key evaluations include braking performance tests on dry hard slopes, vibration measurement at specific operating speeds, and fuel tank pressure and fire resistance tests. It also details a specific protective device strength test (Appendix A), applying a vertical load to access steps to ensure structural integrity. Testing must be conducted strictly according to the referenced national test procedures.

Questions fréquentes

What products are regulated under GB 18447-2025?

It applies to agricultural and forestry tractors, including wheeled tractors, tracklaying tractors, walking tractors, and belt-drive tractors used in China. It is mandatory for all tractor manufacturers targeting the Chinese market.

Are there any significant updates from the previous versions of GB 18447?

This version merges and replaces four previous standards (GB 18447.1 to 18447.4-2008). Major updates include the addition of safety requirements for electric control systems, autonomous driving systems, falling object protective structures (FOPS), and updated braking performance criteria for mountain tractors.

How does GB 18447-2025 differ from ISO standards?

It is a Type C standard based on GB/T 15706. While it aligns with general safety principles, it incorporates specific Chinese national requirements and references international testing codes like OECD Code 4 and OECD Code 8 for protective structures. For Chinese compliance, this local standard takes precedence over general international standards.

The summary above provides a high-level overview of GB 18447-2025. To ensure complete compliance for your tractors entering the Chinese market, a precise and professional translation of the full technical specifications is essential.
