Compared with JB/T7235-1994, this standard has the following major changes: According to the changes in technical conditions, some test methods are supplemented. For test methods with special standards, they are directly quoted. Some test methods are determined by referring to the test methods of other vehicles. A large part of the methods have been slightly modified according to actual conditions. Some technical requirements that are not specified in the technical conditions are deleted from the test methods in this standard. Appendix A and Appendix B of this standard are normative appendices. This standard replaces JB/T7235-1994.
This standard is proposed by the China Machinery Industry Federation. This standard is under the jurisdiction of the National Agricultural Transport Vehicle Standardization Technical Committee. JB/T7235-2002
This standard was drafted by the National Agricultural Machinery Quality Supervision and Inspection Center, Sichuan Highway Machinery Factory, Yuejin Automobile Group Hongyun Agricultural Vehicle, National Machinery Quality Supervision and Inspection Center, and Anhui Feicai (Group) Co., Ltd. The main drafters of this standard are Jin Suofang, Weng Li, Jiang Suolin, Guo Qingchen, and Xiong Junsong. This standard was first issued in 1994.

5.1 Measurement conditions
5.1.1 Except for the commonly used accompanying vehicle and the original spare tire, no overloaded cargo, sundries, mud, etc. are allowed on the four-wheel vehicle under test. 5.1.2 Fuel, lubricating oil, coolant and other working fluids should be filled to the highest liquid level position specified in the technical documents. 5.1.3 All adjustable or changeable parts that affect the outer dimensions of the four-wheel vehicle under test, such as the flip cab and self-unloading cargo box, should be in a stable state with the minimum outer dimensions. 5.1.4 When measuring the dimensional parameters, the four-wheel vehicle under test should be parked on a hard and horizontal ground. The ground slope within the test range should not be greater than 0.3%, and the ground flatness should be within 3mm/m.
5.1.5 The four-wheel vehicle under test is in a straight driving position. For adjustable passenger seats, they should be placed in the middle position. 5.1.6 During the measurement, the engine is turned off, the gear lever is placed in the neutral position, the brake is released, and no pads are allowed. 5.1.7 The measurement can be carried out before running-in.
