6、 hose will be tested with Fuel C and Fuel C with 10% ethanol. This document has been modified to remove the fuel aging and permeation specifications regarding methanol testing (85% ASTM Fuel C with 15% Methanol by volume).1. SCOPE This SAE Standard specifies requirements for two types, three classes

7、 and four styles of reinforced hose and non-reinforced tubing for conveying gasoline or diesel fuel aboard small craft including pleasure craft whose fuel systems are regulated under 33 CFR 183 Subpart J. Refer to SAE J1942 Hose and Hose Assemblies for commercial marine nonmetallic flexible hose or

8、hose assemblies used in systems on board commercial vessels inspected and certified by the U.S. Coast Guard. Refer to SAE J2046 Personal Watercraft Fuel Systems for fuel hose used on Personal Watercraft. 1.1 Hose Types Two types of hose meeting 33 CFR 183 Subpart J requirements with respect to fire

FLAMMABILITY Quarter-inch-wide strips cut longitudinal from the cover, which have been removed from the hose, shall be used for this test. A Bunsen burner shall be used to start burning of the strips until approximately 12

28、.7 mm (1/2 in) of the strip is burning vigorously. Remove the burning strip from the flame and hold it horizontally with the outside facing upward. The flame shall be self-extinguishing within 60 s. The average time of at least six determinations shall be used. The test shall be conducted in a draft

29、-free atmosphere. 5. FIRE RESISTANCE-TYPE A ONLY 5.1 Principle The hose, including its coupling if applicable, filled with N Heptane, is subjected to a flame for 2-1/2 min, then to a hydraulic pressure test, after which it shall show no leakage. 5.2 Sampling Three hose samples shall be tested in tur

30、n without showing leakage. 5.3 Equipment Test equipment shall be utilized as shown in Figure 1. Thermocouples shall be located in the same horizontal plane as the sample, at a distance of 12 mm (0.5 in) from the surface of the hose and 25.4 mm (1 in) from the end of the hose. The fuel pan shall be a

31、 straight-sided container with minimum width, length, and depth dimensions of 355 mm (14 in) x 355 mm (14 in) x 40 mm (1.5 in). 5.4 Test Procedure The following test procedure or an equivalent test procedure may be utilized to perform this test. If the hose is intended to be delivered with couplings

32、, at least one of the couplings shall be located directly above the fuel pan. Fill the hose with fuel by opening the fuel valve; ensure that no air is left in the hose. Check that the air velocity outside the device does notexceed 0.5 m/s. Pour heptane into the fuel pan and ignite it. Ensure that at

33、 least one coupling is exposed to the flame. Allow the heptane to burn for 150 s and record temperatures. At the end of the period of 150 s, extinguish the flame. The test shall be repeated on a new sample if the temperature has not reached 650 C (1202 F). Open the valve so that fuel can flow throug

34、h the hose under test. As soon as steady flow is achieved, close the valve and submit the hose to a hydrostatic pressure corresponding to 900 mm (35.4 in) of fuel. Note any sign of leakage.

35、ple Three individual production 38 mm (1-1/2 in) ID hoses of identical construction shall be selected for a test lot. These hoses shall incorporate a cover compounded and constructed the same as for all other sizes to be qualified by this test lot. No hose to be qualified by this test lot shall have

36、 a cover thickness less than those of the test lot. After 1000 test cycles each hose of the test lot shall not have any rigid helix exposed at the point of contact with the abrasive surface. 6.2 Procedure The test hoses shall be preconditioned for at least 24 h at 23 C 2 C (73 F 3.6 F) and 50% 5% re

37、lative humidity. Testing shall then be performed at the preconditioning temperature with an unused abrasive surface for each hose sample. The test hose shall be mandrel supported and rotated at a constant speed of 80 rpm 2 rpm. The rotation hose shall be subjected to a laterally moving abrasive surf

38、ace (80 grit, coarse, Al2O3emery cloth) parallel to the longitudinal axis of the test hose. The abrasive surface shall be 25 x 75 mm 5 mm (1 x 3 in 0.25 in) firmly affixed to a hard surface which will cycle back and forth 75 mm 5 mm (3 in 0.25 in) in each direction. A constant normal force of 45 N 5

39、 N (10 lb 1 oz) shall be applied to the abrasive surface. One test cycle equals 360 degrees rotation of the outside diameter and one back and forth movement of the abrasive surface. See Figure 2 for a typical apparatus. SAE J1527 Revised FEB2011 Page 7 of 11FIGURE 2 - TYPICAL TEST APPARATUS 7. BURST

40、 TEST The minimum burst pressure per ASTM D 380 for hose sizes through 25.4 mm (1 in) ID shall be 1.20 MPa (175 psi) and for hose sizes over 25.4 mm (1 in) ID shall be 0.62 MPa (90 psi). These hoses have maximum working pressures of 0.24 MPa (35 psi) and 0.12 MPa (18 psi), respectively. Applications

41、 which exceed the working pressure values stated previously shall have burst pressures which equal or exceed four times the working pressure of the hose. 8. VACUUM COLLAPSE TEST A 1 m (3.28 ft) length of hose or a hose assembly shall be held in a straight line, and no diameter shall decrease by more

42、 than 20% during application of a vacuum of 67.5 kPa (20 in Hg) for a minimum of 15 s and not more than 60 s. The vacuum collapse test on preformed parts should be performed on the finished part. This requirement shall not apply to style R1 hose sizes larger than 25.4 mm (1 in). 9. COLD FLEXIBILITY

The test specimen shall be conditioned per ASTM D 380 at 20 C 2 C (4 F 3.6 F) for 5 h and then flex in the cold chamber through 180 degrees from the centerline to a diameter of ten time

44、s the maximum OD of the hose. The flexing shall take place within 4 s and the hose must not fracture or show any cracks, checks, or breaks in the tube or cover. Proof pressure of 0.68 MPa (99 psi) may be applied to determine tube damage. For styles R1, R3 and R4 straight hose over 19.05 mm (3/4 in)

45、ID and all preformed hose, prepare three specimens 100 x 6 mm (4 x 0.25 in) from the whole hose wall. These specimens shall be conditioned per ASTM D 380 at 20 C 2 C (4 F 3.6 F) for 5 h in unrestrained loop positioned between two jaws 50.8 mm (2 in) wide and 63.5 mm (2.5 in) apart. After conditionin

46、g and while still in the cold chamber, the jaws shall be brought together as rapidly as possible until they are 25.4 mm (1 in) apart. The specimens shall not fracture or show any cracks, checks, or breaks. For style R2 hose, a test specimen of the whole hose shall be conditioned per ASTM D 380 at 20

47、 C 2 C (4 F 3.6 F) for 5 h and then, without removing it from the cold chamber, it shall be compressed to 50% of its original ID between parallel plates in 8 to 12 s. After removal and allowing it to come to room temperature, it shall be carefully examined visually. The specimen shall not show any c
