Subject content and scope of application
This standard specifies the prevention of fuel leakage caused by automobile accidents Technical requirements and test methods for fuel leakage caused by collision. This standard applies to cars, and passenger cars with no more than 9 seats may also be implemented by reference. 2 Terminology
2.1 Barrier wall
GB11553-89
Barrier wall refers to a reinforced concrete block that can withstand the impact of a car. Its width is not less than 3m and its height is not less than 1.5m. Barrier wall The thickness of the wall should be such that its mass is at least 70t, and its impact surface should be equipped with plywood (or thin boards) with a thickness of about 20mm. 3 Technical requirements
When tested according to Article 4, the total amount of fuel leaked from the fuel tank and fuel pipe shall not exceed 200mL within 5 minutes. 4 Test method
4.1 Test device
4.1.1 The impact surface of the obstacle wall must be perpendicular to the center line of the runway. The obstacle wall must be fixed on the test track. If it floats on the road, some additional obstacles must be attached. Block and support the device to prevent its movement. Obstacles with the same performance can also be used instead. 4.1.2 The accuracy of the vehicle speed measuring instrument should be within ±2%, and the minimum resolution scale should be within 0.5km/h. 4.2 Status of the test vehicle
4.2.1 The mass of the test vehicle is the equipped unladen mass. 4.2.2
The fuel tank and oil pipe should not be in contact with the parts of the car. 4.2.3 Add non-flammable liquid to the fuel tank. The viscosity and specific gravity of the liquid are similar to those of practical fuel. 4.2.4 The filling amount of non-flammable liquid should be greater than 90% of the fuel tank capacity. 4.2.5 Devices other than fuel tanks and fuel pipes may not be filled with non-flammable liquids. 4.3 Test methodbzxZ.net
4.3.1 The test car travels at a speed of 50±2km/h (40±2km/h for mini-cars), and the driving direction is 90°±5° with the impact surface of the obstacle wall, and hits the obstacle wall. .
4.3.2 After the impact, check the fuel tank and fuel pipe as quickly as possible for leaks, and check the condition of the leak and the total amount of leakage. 5Test record
The test results are recorded in Appendix A (reference part). State Bureau of Technical Supervision approved 224 on August 10, 1989
