29、s International Standard specifies general requirements and physical tests for non-fire-resistant hoses for conveying petrol and diesel oil at low pressure, designed for a working pressure not exceeding 0,34 MPa for hoses with nominal bore up to and including 10 mm, and 0,25 MPa for hoses with a lar
30、ger bore. It applies to hoses for small craft of up to 24 m length of hull with permanently installed inboard engines. NOTE 1Specifications for fire-resistant fuel hoses are laid down in ISO 7840. 2 Normative references The following standards contain provisions which, through reference in this text
31、, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editi
32、ons of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.

The nominal bore shall be in accord
35、ance with ISO 1307. Hoses shall demonstrate suitability for marine use by complying with the requirements of the tests in clause 5. They shall be marked according to clause 6. 4 Nominal bore Table 1 gives some nominal bores, based on the R 10 series in ISO 31). Tolerances shall be as indicated in Ta

38、ure (23?C). Empty the liquid out and fill the hoses or test pieces with cold water; subject them to bursting pressure, as specified in ISO 1402. The bursting pressure shall be at least 1,36 MPa for hoses of nominal bore up to and including 10 mm, and 1 MPa for hoses with a larger bore. 5.2 Suction r
39、esistance test Carry out the test in accordance with ISO 7233:1991, method A, using the test conditions specified in Table 2. The time shall be 60 s and the diameter of the sphere used 0,8d. 5.3 Volume change in liquid C Determine the change in volume of the hose (tube and cover) by the procedure de
40、scribed in ISO 1817. Table 2 Pressure conditions for suction resistance test Place the test pieces in liquid C at standard laboratory temperature (23?C) for 70 h 2 h. If the hose is made of a homogeneous compound (with or without reinforcements), the swelling in liquid C shall not exceed 30 % by vol
41、ume. For hoses 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 in liquid C shall not exceed 30 % for the tube and 120 % for the cover. 5.4 Mass reduction in liquid C Determine the reduction in ma
42、ss of the inner layer by the procedure described in ISO 1817. Treat the test pieces as specified in 5.1. The reduction in mass of the inner layer shall not exceed 8 % of the initial mass of the test pieces. NOTE 2A reduction in mass of 8 % corresponds to a decrease in volume of approximately 10 %. 5
43、.5 Effect of ozone The hose shall be tested as described in ISO 7326:1991, Method 1. The sample shall show no visible cracks at ?2 magnification. 5.6 Accelerated ageing After ageing for 72 h in a ventilated oven at a temperature of 100?C, as described in ISO 188, the increase in hardness of the cove
44、r shall not be more than 10 IRHD above the initial value. 5.7 Fuel permeation A permeation rate shall be tested. When tested according to the method described in Annex A or equivalent, the hoses shall be classified in the following way. Class 1: hoses with a permeation rate of 4 g/(m2h) or less; Cla
45、ss 2: hoses with a permeation rate over 4 g/(m2h), up to and including 12 g/(m2h).

Then the test pieces are filled with test liquid and the liquid lost by permeation during time periods of 24 h is determined by weighing for 15 consecutive days or until a peak has been established. A.2 Sampling Three test pieces of the hose shall be tested simultaneously. The test pieces shall be approximately 300 mm long. A.3 Equipment The test equipment shall be as shown in Fig
