適用範囲

This standard applies specifically to agricultural wheeled tractors with direct-drive transmission operating within China. It establishes safety requirements to address physical hazards and risks during the machine's lifecycle as defined in GB/T 15706.1. This standard is mandatory for all manufacturers of wheeled tractors entering the Chinese market, while explicitly excluding belt-driven and crawler tractors.

技術要求

The standard comprehensively outlines mandatory safety requirements across several critical categories. It specifies structural and protective measures, including the requirement for safety glass on cab front windshields, specific strength parameters for hydraulic piping, and strict leak-proof testing criteria for fuel tanks. Manufacturers must ensure all exposed rotating components are equipped with durable protective guards. Regarding operational safety, the standard sets clear limits for environmental noise, exhaust smoke opacity, and driver whole-body vibration. It also mandates strict braking performance criteria, requiring reliable parking brakes on a 20% dry slope and specific deceleration metrics for cold-state braking. For tractors with a maximum speed exceeding 30km/h, enhanced braking performance rules apply. The standard details specific requirements for lighting and signaling devices, mandating minimum quantities for headlights, brake lights, and turn signals. It sets minimum luminous intensity for headlights based on the tractor's rated power and requires precise beam positioning to ensure safe operation. Additionally, it defines driver visibility parameters, limiting the size and number of blind-spot shadows within a 12m visibility radius. Finally, the standard enforces safety operation identification and user information protocols. This includes the use of standardized operating symbols, permanent product nameplates, and the placement of safety warning signs at critical hazard zones. Manufacturers must provide a comprehensive user manual detailing safe operating procedures and emergency measures.

試験方法

Compliance verification involves a series of standardized tests, primarily referencing the GB/T 3871 series for agricultural tractor testing procedures. Key evaluations include braking performance tests on dry slopes, exhaust smoke opacity measurements, and environmental noise mapping. Additionally, the standard outlines specific procedures for evaluating driver visibility, measuring whole-body vibration, and verifying the flame-retardant characteristics of cab interior materials. A dedicated screen method or headlight tester is used to verify headlight beam alignment.

よくある質問

What products are regulated under GB 18447.1-2008?

This standard specifically regulates agricultural wheeled tractors with direct-drive transmission operating in China. It explicitly excludes belt-driven and crawler tractors, which are covered by other parts of the GB 18447 series.

Are there any significant updates from the previous GB 18447.1-2001 version?

The 2008 version introduces several new mandatory requirements, including stricter exhaust smoke limits, flame-retardant properties for cab interior materials, enhanced braking performance for tractors exceeding 30km/h, and new parameters for driver whole-body vibration and visibility.

How does GB 18447.1-2008 differ from ISO standards?

The standard incorporates methodologies aligned with international guidelines, frequently referencing ISO standards (such as ISO 500-1 for PTO safety and ISO 12100-1 for basic machinery safety concepts). However, it establishes specific national limit values and testing procedures tailored for the Chinese market.

The summary above provides a high-level overview of GB 18447.1-2008. To ensure complete compliance for your agricultural machinery entering the Chinese market, a precise and professional translation of the full technical specifications is essential.
