3.1 General
3.1.1 The fuel tank must be designed to meet the requirements of coal, machinery and chemical industry under the expected conditions of use. 3.1.2 The fuel tank and its adjacent parts must be designed to not cause any damage to the fuel tank and the fuel tank frame. 3.1.3 The new fuel tank must be properly tested. 3.1.2 The fuel tank must be tested for leakage resistance and the pressure must be equal to the workpiece pressure. The pressure must not be less than the absolute value under any circumstances. t||3.1.5 There must be three devices (ventilation valve) to allow additional pressure or allow 1 wire pressure, and the ventilation source must be designed to eliminate the danger of being trapped.
3.1.6 The fuel tank cannot be closed from the front of the injection port to release any high positive pressure and forget to place the flow piece, that is, when the fuel tank is completely inverted, its degree of oil volume will not exceed the single:
3.2 Open metal fuel tank test requirements
Non-metal material is made in the following method to test the sequence of operation, 32.1 Expansion test
The fuel tank is filled with 50% of the rated capacity of the fuel, and placed in an environment with a gas source of 49:2. After the fuel tank is emptied, place the tank in a test environment with a minimum combustion temperature and pressure of 3℃ until the fuel is discharged. The fuel loss shall not exceed 20% every 24 hours. The quality loss must not exceed the specified value. GB 194B2—2004
The test shall be carried out again under an environment with a humidity of 12:1 and a humidity of 2d. All other conditions shall remain unchanged (including the test pre-storage period of 2d). The fuel quality loss obtained under this environment shall not exceed [(4E). 3.2.2 Cold shock test
The tank is filled with a liquid with a freezing point lower than 1/2 of the rated capacity. The temperature of the liquid in the fuel tank must be maintained within 100% of the rated capacity during the cold shock test. The temperature of the fuel tank must be kept within 100% of the rated capacity under the ambient temperature. The fuel tank can also be filled with a liquid that has been properly cooled for a long time. The fuel tank can be kept at the rated capacity until the test temperature reaches 11. During the test, a remote casting is used to perform a shock test on the fuel and the fuel tank. The shape of the bull head must be an equilateral body. The impact rate of the dragon head point and the material matrix will not be small. The points selected for the test must be those points that are considered to be in a dangerous state due to the installation of the fuel tank and its location in the work. A shock test on any of the points should not produce a wave. 3.2.3 Wet-dry test
Pour the fuel into water with a temperature of 53°C to a certain volume, and apply a relative pressure not less than (for example, the relative working pressure of the fuel tank is greater than 2 times of the relative working pressure of the fuel tank). The normal pressure applied to the fuel tank must not cause any deformation caused by the impact of the fuel (the tank must not be perforated). When evaluating the seat shape of the fuel pin, the installation conditions must be met. 3.2.4 Fuel resistance test
Take the same tensile test piece from the flat surface of the fuel tank: make a tensile test piece at a temperature of 3-2 and a tensile speed of om to determine its tensile strength and elasticity: take the test piece from the surface of the fuel tank that has been stored for 28 hours and then test the new fuel oil with the same test conditions. Compare the results of the two tests before and after. There is no difference between the two tests. 3.2.5 Fire test
The injection material in the test described in Appendix A shall not exceed 0.64nu: *3.2.6 High temperature test
The fuel tank shall not show obvious plastic deformation or hidden frost in a humid environment. After the test, the tank must be fully lubricated and can be used. The test materials must be considered. 4. Requirements related to installation on vehicles
4.1 Fuel tank
Design, manufacture and installation of fuel accessories system to realize its function under any conditions. 4.2 Fuel supply system
The engine fuel supply system components must be continuous in the vehicle channel The fuel supply system should be designed, manufactured and installed to ensure that it can withstand any internal and external stress. Due to the structure of the engine, the movement of the components caused by the triggering cannot be fast enough to withstand the normal falling force.

Fire test test method
GB19482—2004
A fully enclosed test smoke chamber with a heat-resistant airtight structure can be used to allow the test smoke to be viewed from behind the sample. The test sample must be closed during the test period and should be started immediately when the test is completed to remove the harmful gas products produced by the combustion environment. The test can be carried out within 1 week under the following conditions: Inlet: When the exhaust fan is running, the metal pen wall and bottom must have holes to ensure that there is insufficient air to prevent the burning sample from igniting. A.1.2 Bracket

Scale unit, mm
A2 Test sample
A.2.1 A sample of at least 125 mm=mm, 12, mm=.2 m must be taken with a gas tank adhesive tape. If the fuel tank shape is not used, this must be done. The material of the fuel tank body must be injection molded into 3-3 ears and sufficient workpieces must be drawn to obtain the required test product. A.2.2 Each test sample can be marked with parallel strips, one with a distance of 25 mm from the front and the other with a distance of 10 m from the other end. A.2.3 The edges of the test sample must be clearly visible and the sawn edges must be polished with fine sand to be smooth and bright. A.3 Test method
A3. Place the test sample on a support with the end near the marking line at a 45° angle to the horizontal axis of the sample. Install a metal wire mesh as described in 1.4 horizontally at a distance of 1 m below the edge of the test sample so that the edge of the wire mesh does not protrude from the vertical axis of the sample (Figure A.1). Before each test, the wire mesh must be burned off and replaced, or the wire mesh must be replaced. A full water tank should be placed in the test chamber to receive the heat particles that may fall during the test. 3.2 The air supply to the burner must be adjustable to obtain a blue flame of approximately 25L. A.3.3 The flame detector must be placed outside the flame increase chain and test stop 7 as shown in Figure A.1, and the timer should be started at this time. The flame detector should be placed in contact with the test sample 3. If the product is deformed, melted or shrinks from the flame sink: the flame detector must be used to detect the product. If the test period is seriously changed, the test station should be removed. 30, the burner must be removed after or before the 25m mark is reached. If the flame increase reaches the mark before the burner is opened, the burner must be turned off for at least 4m. 4.3.4 When the second sinking reaches the 25mm mark, the timing starts to reverse, and the time is: A.3.5 When the combustion stops (with or without flame) or reaches the 1mm mark, the timing stops and the time at this time is recorded as t.
A.3.6 If the test sample has a mark of about 100mm, then start from the 0.73 mark and cut along the shorter edge of the sample to measure the unburned length. The result should be rounded to mm. The length must be equal to 10 0am minus the length of the plate indicated in mm A3.7 If it is to be verified that the product has burned to or passed the 1013 mark, the burning rate is: 75 (mm/6) || tt || 4.3.3 or Fort (A.8.1-A.3.7) test until 3 samples have burned to or exceeded the 100mm mark. If 10 products are tested: If 1) of the products in the column burns to or temporarily passes the [0Cmm mark, use 0 new samples for the repeat (3.1-A.3.7) test.
A.4 Expression of test results
A.4.1 If at least 2 samples have burned to the 100m mark, the result shall be expressed as the average burning speed (mm/s), that is, the average burning speed of all samples that have reached this mark. A.4.2 If none of the samples or only 1 of the 20 samples has burned to the 100m mark, the average burning time or the average burning length in meters shall be used to express the result:
A4.2.1 Half-average burning time (ACT) shall be: (te--2G)
Where sample length:
: -- the time from the flame touching the sample to the time the sample fire is extinguished. AT is rounded to the nearest multiple. If the burning time does not last longer than n, it is recorded as less than 5 nm. In any case, the A value cannot be written as 0. If a single sample is tested, its burning speed is calculated as 10 μm.
