35、ng pressure shall be at least 1,4 MPa for hoses with an inner diameter of 10 mm or less and 1,00 MPa for hoses with an inner diameter of more than 10 mm.5.4 Vacuum collapse testCarry out the test in accordance with ISO 7233:2006, method A, using the test conditions specified in Table 2.Table 2 Press

The sphere shall pass freely through the hose while under vacuum.5.5 Volume change in test liquidsD
37、etermine the change in volume of the hose (tube and cover) by the procedure specified in ISO 1817.Completely submerge the test pieces in test liquids as specified in 5.2 at a temperature of 40 C 2 C for 40 days.If the hose is made of a homogeneous compound (with or without reinforcement), the swelli
38、ng shall not exceed 35 % by volume as measured by displacement in water. For hose with an inner layer of fuel-resistant material and a cover of another material mainly intended for weather and ozone resistance, the increase in volume shall not exceed 35 % for the tube and 120 % for the cover.5.6 Mas
39、s reduction of test hoseDetermine the reduction in mass of the hose by the procedure specified in ISO 1817. Fill three hoses or sample lengths from the hoses with test liquids, as specified in 5.2, and store them for 40 days in air at a temperature of 40 C 2 C.The reduction in mass of the inner laye
40、r shall not exceed 8 % of the initial mass of the test pieces.NOTE A reduction in mass of 8 % corresponds to a decrease in volume of approximately 10 %.5.7 Effect of ozoneThe hose shall be tested in accordance with ISO 7326:2006, method 1.

The flexing shall take place within 4 s and the hose shall not fracture or show any cracks, checks or breaks in the tube or cover.For straight hoses larger than 19 mm inner diame
44、ter and all pre-formed hoses, prepare three samples (100 5) mm (6 1) mm from the whole hose wall and condition them for 5 h at a temperature of 20 C 2 C in an unrestrained loop, position between two jaws 50 mm wide and 64 mm apart. While in the cold chamber, bring the jaws together rapidly until the
45、y are 25 mm apart. The samples shall not fracture or show any cracks, checks or breaks.5.10 Abrasion test 38 mm inner diameter and larger fuel fill hose with embedded wire reinforcementHose samples of 38 mm inner diameter shall be selected for the test. Larger inner diameter hose sizes to be qualifi
46、ed by the test shall not have a cover thickness or construction less than those of the test samples.Three identical 38 mm inner diameter hose samples shall be tested. Condition hose samples for at least 24 h at a temperature of 23 C 2 C and 50 % 5 % relative humidity. The test hose shall be mandrel-
47、 (core-) supported and rotate at a constant speed of 80 rev/min 2 rev/min. Subject the hose to a laterally moving abrasive surface, i.e. 80 grit aluminium oxide (Al2O3) emery cloth, parallel to the longitudinal axis of the hose. The abrasive surface shall be (25 5) mm (75 5) mm affixed to a hard sur
48、face which will cycle back and forth 75 mm 5 mm in each direction while loaded with a constant normal force of 45 N 5 N. One test cycle shall equal one 360 rotation of the outside diameter of the hose and one back and forth movement of the abrasive surface. After 1 000 cycles, the three test samples
49、 shall have no helical wire reinforcement exposed at the point of contact with the abrasive surface.5.11 Dry heat resistance testAfter heat ageing for 70 h at a temperature of 100 C 2 C, samples taken from the cover material shall not have a reduction in tensile strength of more than 20 % or a reduction in elongation at break of more than 50 % of the original values of the unheated samples.5
