Область применения
This standard applies to the regulation of dynamic environmental noise and operator position noise (ear-level) for various agricultural and industrial tractors. Specifically, it covers wheeled tractors, crawler tractors, walking tractors, and boat-type tractors. It is mandatory for all manufacturers producing or importing these tractor types into the Chinese market. The standard does not apply to static environmental noise, as this metric was removed in the latest revision.
Технические требования
GB 6376-2025 establishes strict noise emission limits categorized by tractor type, transmission mode (e.g., belt drive vs. direct drive), and rated power (P in kW). The standard evaluates two primary noise metrics: dynamic environmental noise and operator ear-position noise. For operator position noise, the limits are further differentiated based on the presence and type of a cab. Categories include no cab, enclosed cab, and other cab types. Manufacturers must ensure their products meet the specific dB(A) limits assigned to their tractor's power tier and cab configuration. A notable update in this 2025 edition is the inclusion of boat-type tractors (both three-wheel and four-wheel configurations) and the exclusion of static environmental noise testing. Additionally, for certain specialized equipment like metallic crawler tractors, the dynamic environmental noise requirement is exempted, focusing compliance solely on operator hearing protection.
Методы испытаний
The standard mandates specific testing procedures based on the tractor category. Noise measurement for walking tractors must be conducted according to GB/T 6229. For wheeled, crawler, and boat-type tractors, dynamic environmental noise is measured following GB/T 41971, while the operator position noise evaluation follows GB/T 3871.8. Manufacturers must refer to these referenced testing standards to ensure accurate compliance verification.
Частые вопросы
What products are regulated under GB 6376-2025?
This standard regulates the noise emissions of wheeled tractors, crawler tractors, walking tractors, and boat-type tractors. It is mandatory for all these tractor types manufactured or sold in China.
Are there any significant updates from the previous version of GB 6376?
Yes, compared to the 2008 version, this edition has updated the noise limits for wheeled and crawler tractors, added specific limits for boat-type tractors, and removed the requirements for static environmental noise. The measurement methods have also been comprehensively updated.
How does GB 6376-2025 handle noise measurement procedures?
The standard references Chinese national testing methodologies rather than ISO standards directly. For example, it mandates the use of GB/T 41971 for dynamic environmental noise measurement. Manufacturers must ensure compliance is verified using these specific Chinese test procedures.
The summary above provides a high-level overview of GB 6376-2025.
