21、 Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the
22、right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Internatio
23、nal Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication a
24、s an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

27、d diesel oil designed for a working pressure not exceeding 0,34 MPa for hoses with inner diameter up to and including 10 mm and 0,25 MPa for hoses up to 63 mm inner diameter in craft of hull length up to 24 m. It applies to hoses for small craft with permanently installed fuel systems. Specification
28、s for fire-resistant hoses are laid down in ISO 7840. 2 Normative references The following referenced documents are indispensable for the application of this document.

34、hree hoses or sample lengths from the hoses with test liquid C as specified by ISO 1817:2005 and store them for seven days in air at an ambient temperature of 23 C 2 C. Empty the liquid out and fill the hoses or sample lengths with cold water; subject them to hydrostatic pressure as specified in ISO
35、 1402. The hose shall withstand a hydrostatic pressure of at least 1,4 MPa for hoses of 10 mm or smaller inner diameter and 1,0 MPa for hoses with inner diameter larger than 10 mm. 5.2 Vacuum collapse test Carry out the test in accordance with ISO 7233:2006, method A using the test conditions specif
36、ied in Table 2.

37、the diameter of the sphere 0,8 d (inner diameter of the hose). The sphere shall pass freely through the hose while under vacuum. 5.3 Volume change in liquid C Determine the change in volume of the hose (tube and cover) by the procedure specified in ISO 1817. Place the sample lengths of hose in test
38、liquid C at an ambient temperature of 23 C 2 C for 70 h 2 h. If the hose is made of a homogeneous compound (with or without reinforcement), the swelling in test liquid C shall not exceed 35 % by volume as measured by displacement in water. For hose with an inner layer of fuel-resistant material and
39、a cover of another material mainly intended for weather and ozone resistance, the increase in volume in test liquid C shall not exceed 35 % for the tube and 120 % for the cover. 5.4 Mass reduction in liquid C Determine the reduction in mass of the hose by the procedure specified in ISO 1817. Fill th
40、ree hoses or sample lengths from the hoses with test liquid C, as specified in ISO 1817:2005, and store them for seven days in air at an ambient temperature of 23 C 2 C. The reduction in mass of the inner layer shall not exceed 8 % of the initial mass of the test pieces. NOTE A reduction in mass of
41、8 % corresponds to a decrease in volume of approximately 10 %. 5.5 Effect of ozone The hose shall be tested in accordance with ISO 7326:1991, method 1. The sample shall show no visible cracks at 2 magnification. 5.6 Fuel permeation The permeation rate for the hoses shall be determined according to t
42、he method specified in Annex A or an equivalent test method. The hoses shall be classified in the following way and marked in accordance with Clause 6: Type 1: hoses with a permeation rate of 100 g/m2 or less per 24 h. Type 2: hoses with a permeation rate of over 100 g/m2 per 24 h, up to and includi
43、ng 300 g/m2 per 24 h. 5.7 Cold flex test For straight hose of 19 mm inner diameter and smaller, condition hose samples for 5 h at an ambient temperature of 20 C 2 C. Flex in the cold chamber through 180 from the centreline to a diameter of 10 times the maximum outside diameter of the hose. The flexi
44、ng shall take place within 4 s and the hose shall not fracture or show any cracks, checks or breaks in the tube or cover.

Larger inner diameter hose sizes to be qualified by the test shall not have a cover thickness or const
47、ruction 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 an ambient temperature of 23 C 2 C and 50 % 5 % relative humidity. The test hose shall be mandrel- (core-) supported and rotate at a constant sp
48、eed 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 surface which will cycle back and forth 75 mm 5 m
49、m in each direction while loaded with a constant normal force of 45 5 N.
