FLAMMABILITY Quarter-
26、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 12.7 mm (1/2 in) of the strip is burning vigorously. Remove the burning strip from the flame and hold
27、 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-free atmosphere. 5. FIRE RESISTANCE-TYPE A ONLY 5.1 Principle The hose, including its coupling if
28、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 turn without showing leakage. 5.3 Equipment Test equipment shall be utilized as shown in Figure 1. The
29、rmocouples 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 straight-sided container with minimum width, length, and depth dimensions of 355 mm (14 in) x 355
30、mm (14 in) x 40 mm (1.5 in).

31、ollowing test procedure or an equivalent test procedure may be utilized to perform this test. If the hose is intended to be delivered with couplings, 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 l
32、eft in the hose. Check that the air velocity outside the device does not exceed 0.5 m/s. Pour heptane into the fuel pan and ignite it. Ensure that at 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
33、 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 through 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
34、in) of fuel. Note any sign of leakage. FIGURE 1 - FIRE TEST EQUIPMENT 6. ABRASION TEST-STYLE R2 ONLY 6.1 Principle 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 sa
35、me as for all other sizes to be qualified by this test lot. No hose to be qualified by this test lot shall have 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

37、d for at least 24 h at 23 C 2 C (73 F 3.6 F) and 50% 5% relative 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 h
38、ose shall be subjected to a laterally moving abrasive surface (80 grit, coarse, Al2O3 emery 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.
39、25 in) in each direction. A constant normal force of 45 N 5 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. FIGURE 2 - TYPICAL TE
40、ST APPARATUS 7. BURST 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), respe
41、ctively. Applications 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 s
42、hall decrease by more 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).

COLD FLEXIBILITY For styles R1 and R3 straight ho
44、se 19.05 mm (3/4 in) ID and under, the whole hose shall be used for this test. 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 times the maximum OD of the hose. The fl
45、exing 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 and R3 straight hose over 19.05 mm (3/4 in) ID and all preformed hose, prepare three
46、 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 conditioning and while still in the cold chamber, t
47、he 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 C 2 C (4 F 3.6 F) for 5 h and then, wit
48、hout 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 cracks or breaks. 10. TENSILE STRENGTH AND ELONGATION a.
