Compliance overview
Scope and applicability
This standard applies specifically to agricultural vehicles operating within China. It establishes the mandatory noise limits for both exterior acceleration noise and noise at the driver's operating position. Compliance is required for all agricultural vehicle manufacturers seeking market access, covering categories such as three-wheeled and four-wheeled agricultural transport vehicles.
Technical requirements
GB 18321-2001 specifies the acoustic emission limits for agricultural vehicles to mitigate environmental and occupational noise pollution. The standard categorizes vehicles based on their engine configuration, specifically differentiating between multi-cylinder and single-cylinder diesel engines. For each vehicle category, the standard establishes distinct maximum allowable noise levels for two critical scenarios: noise emitted outside the vehicle during acceleration and noise experienced at the driver's operating position. These dual limits ensure both environmental protection and operator safety. All technical content within this standard is designated as mandatory, meaning that adherence to the specified decibel limits is a strict legal requirement for production and sales in China.
Testing methods
The noise measurement procedures are not detailed within GB 18321-2001 itself but are instead governed by a referenced industry standard. Specifically, testing must be conducted in accordance with JB/T 7235-1994, focusing on the acoustic measurement protocols outlined in Chapter 13 of that document. Manufacturers must ensure their testing setups align with these specific procedural requirements to achieve valid compliance certification.
