3.5.7 Length change. The length of the hose shall not change more than 7 percent when tested in
accordance with 4.6.7.
3.5.8 Burst pressure. When tested in accordance with 4.6.8 and subjected to the burst pressure
specified in table VIII, the hose shall not leak, disconnect from the couplings, burst, or develop a
permanent blister.
3.5.9 Crush resistance. Testing shall be performed in accordance with 4.6.9. During the test, the
outside diameter shall be not less than 85 percent of the original outside diameter of the hose. After the
load has been released, the outside diameter shall be not less than 95 percent of the original outside
diameter of the hose.
3.5.10 Low temperature bend. Specimens of the tube and cover shall not crack when tested in
accordance with 4.6.10.
3.5.11 Environmental vacuum. The hose assembly shall maintain a vacuum after being tested in
accordance with 4.6.11.
3.5.12 Ozone resistance. When tested in accordance with 4.6.12 and then examined with 2X
magnification, the cover shall not show any evidence of cracking.
3.5.12.1 Hazardous substances and ozone depleting chemicals. The ozone resistance test (see
4.6.12) may contain hazardous chemicals. It shall be handled in accordance with Federal regulations and
guidelines to perform those tests. For further information about toxic chemicals and hazardous materials
list, consult the Environmental Protection Agency web database at
3.5.13 Sediment and fuel color change. When tested in accordance with 4.6.13, change in the fuel
color shall be not greater than 40 and the sediment shall not exceed 2 milligrams per liter.
3.6 Product identification. The hose shall be legibly marked along its longitudinal axis with a fuel-
resistant yellow stripe. The stripe shall be broken at intervals of approximately 2 inches.
3.6.1 Hose labeling. A continuous mylar tape layline shall be cured into the hose during
manufacturing process. The marking , in the minimum of 12 inch (305 mm) increments, shall include all
the information in 3.6.1 a, b, c, and d. The letters shall be legible and contrasting color to the mylar tape.
