Reference number IS0 15540: 1999E) Foreword IS0 (the International Organization for Standardization) is a worldwide federation o f national standards bodies (IS0
9、 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, gover
10、nmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC D
11、irectives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 15540 was prepared by Techn
12、ical Committee ISOTTC 8, Ships and marine technology, Subcommittee SC 3, Piping and machinery. Annex A forms a normative part of this International Standard Q IS0 1999 All rights reserved.

15、tandard is to determine whether and for how long a hose assembly can be exposed to fire, without becoming inoperable, e.g. without becoming untight when subjected to the envisaged working pressure. Despite the fact that the attacking fire is simulated so as to correspond to a fire occurring in pract
16、ice, it cannot be assumed that the duration of resistance to fire as recorded during the test will also occur in the event of an actual fire, as the conditions of installation, which essentially affect the duration of resistance to fire, may vary from case to case. When carried out using the test be
17、nch specified in IS0 15541, the test procedure according to this International Standard is intended to lead to results capable of being reproduced. A specimen test certificate is specified in normative annex A. iii COPYRIGHT International Organization for Standardization Licensed by Information Hand

19、s International Standard specifies a test procedure for determining the fire resistance of hose assemblies with nominal diameters of at least 1 O0 mm. It serves for proving whether, after the period of fire effect on the test bench specified in IS0 15541, hose assemblies continue to be tight, even w
20、hen subjected to proof pressure. Only water is permitted as a test medium. With a view to ensuring maximum safety for both the operating personnel and the test bed in the event of damage to the hose during the test, the use of combustible test media is excluded. 2 Normative reference The following n

The orderer and
26、 operator of the test bench shall agree which fitting types shall be used for the test. The test specimens may be tested either with or without fire sleeves subject to agreement; identification letter B for tests without fire sleeves, identification letter F for tests with fire sleeves. Prior to the
27、 test, the test specimens shall be stored at ambient temperature for 24 h. 5 Number of test specimens The tests shall be carried out on a minimum of three hose assemblies of different nominal diameters, but of identical hose construction. The smallest, the middle and the largest nominal diameter of
28、each series shall be tested. 6 Testbench The tests shall be carried out on a test bench according to IS0 15541. 7 Test performance 7.1 Installation of test specimen The test specimens shall be installed on the test bench such that the burner end extends beyond a hose fitting by at least 20 mm such t
29、hat the fitting is completely enclosed by the flames (see Figure 1).
