5、firmed 2014-04 Superseding J288 MAR2008 Snowmobile Fuel Tanks RATIONALE J288 has been reaffirmed to comply with the SAE five-year review policy. 1. SCOPE To provide minimum performance requirements for non-pressurized fuel tanks used on snowmobiles as defined in SAE J33. 2. REFERENCES 2.1 Applicable

ASTM D 635 Test Method for Rate

8、 of Burning and/or Extent and Time of Burning of Plastics in a Horizontal Position ASTM D 1525 Test Method for Vicat Softening Temperature of Plastics 3. REQUIREMENTS 3.1 The tank shall remain functional in a temperature range of 40 to +60 C when tested in accordance with Section 4. SAE INTERNATIONA

9、L J288 Reaffirmed APR2014 Page 2 of 3 3.2 The tank material specifications should indicate resistance to gasoline, lubricating oils, anti-icing, and other additives that may be used with snowmobile fuel. 3.3 “The plastic material of the fuel tank should be rendered essentially opaque by the addition

10、 of at least 0.5% by weight of a suitable pigment that will not affect, nor be affected by, the fuel. This requirement does not apply to tanks which are so mounted or stored that they are not exposed to sunlight.13.4 Non-metallic tank materials shall comply with the following specifications: 3.4.1 A

11、 maximum burning rate of 0.64 mm/s when tested per ASTM D 635. 3.4.2 A minimum vicat softening point of 110 C when tested per ASTM D 1525, rate A. 3.5 Metal tanks shall not contain dissimilar metal or alloy joints that promote galvanic corrosion. 3.6 Tanks shall not leak after cycling per 4.5. 4. TE

12、STS 4.1 Tests shall be conducted with tank cap and fittings in place. Tanks shall be filled to within 90% of overflow. 4.2 Pressure Test Pressurize an empty tank, using a calibrated pressure gauge, along with its caps and fittings, to a minimum pressure of 35 kPa. Immerse the tank in water for 30 s,

13、 with the pressure applied. If no bubbles or other evidence of leaks are observed in the base material, seams, liquid fittings, fill neck or caps, this test is passed. 4.3 Impact Test 4.3.1 Conditioning Fill three tanks to be tested with snowmobile fuel, allow them to remain at room temperature, for

14、 one week. Empty the tank, and refill with a non-flammable liquid having a specific gravity of not less than 0.7, and a freezing point of no more than 40 C, and which does not attack the tank material.2,34.3.2 Cold Chamber Test Place the filled tanks in a cold chamber at 40 C 3 C. Keep the tanks at

15、this temperature for no less than 5 h after the tank and its contents have stabilized at this temperature. 4.3.3 Drop Test Remove the tank from the cold chamber. Ensure that the fittings and caps are tightly installed. Ensure the fluid temperature is 40 C 3 C. Drop the surface of the tank which is s

16、upported in the snowmobile onto a hard smooth surface from a height of 1.25 m. Tanks attached by fasteners through integral bosses to mounting points on the snowmobile should be mounted in a fixture duplicating the mounting. 1Carbon black imparts maximum resistance to weathering. But if other colors

17、 are desired, cadmium pigments have also been found effective. 2A mixture of ethylene glycol and water usually is satisfactory, but should not be used without inquiry unless recommended by the manufacturer of the tank. 3If the filled tanks are stored indoors, care must be taken to insure the proper

18、ventilation and the absence of any open flame or electrical discharge. SAE INTERNATIONAL J288 Reaffirmed APR2014 Page 3 of 3 4.3.4 Hot Chamber Test Place the same three filled tanks in a hot chamber, filled as in 4.3.1, at 60 C 3 C. Keep the tanks at this temperature for no less than 5 h after the t

19、ank and its contents have stabilized at this temperature. 4.3.5 Drop Test Repeat the drop test of 4.3.3. 4.3.6 Acceptance Repeat the pressure test of 4.2. If no leaks are seen, this test is passed. 4.4 Stress Crack Test Fill 4 tanks with snowmobile fuel, and condition for one week as in 4.3.1. Empty

20、 the tanks. Mount two of the tanks in a fixture which duplicates the mounting system of the snowmobile4. Subject all four tanks to 10 complete temperature cycles of a minimum of 5 h at 40 C 3 C, followed by a minimum of 5 h at 60 C 3 C, repeated within a 14 day period. 4.4.1 Acceptance Repeat the pr

21、essure test of 4.2. If no leaks are noticed, this test is passed. 5.

An (R) symbol to the left of the document title indicates a complete revision of the report. PREPARED BY THE SAE SNOWMOBILE COMMITTEE 4Tanks should be complete with attachments, fuel line, and drain plugs, if any.
