20、zation for Standardization) is a worldwide federation of national standards bodies (IS0 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 establishe
21、d has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take pari in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
22、International Standards are drafted in accordance with the rules given in the ISOAEC Directives, 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 th
23、e member bodies casting a vote. International Standard IS0 15540 was prepared by Technical Committee ISOTTC 8, Ships and marine technology, Subcommittee SC 3, Piping and machinery. Annex A forms a normative part of this International Standard. II 4 egaP EN IS0 15540:2001 Introduction The main object
24、ive of the test described in this International Standard 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
25、 so as to correspond to a fire occurring in practice, 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
26、 case to case. When carried out using the test bench 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 4 egaP EN IS0 15540:2001 Ships and m
27、arine technology - Fire resistance of hose assemblies - Test methods 1 Scope This International Standard specifies a test procedure for determining the fire resistance of hose assemblies with nominal diameters up to 100 mm, and may be used for larger sizes provided proper test bench conditions are o
28、btained. 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 when subjected to proof pressure. Only water is permitted as a test medium. With a view to ensuring maximum safety for both the operating perso
29、nnel 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 normative document contains provisions which, through reference in this text, constitute provisions of this Intemational Standard.

However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the normative document indicated below.

The orderer and operator of the test bench shall agree which fitting types shall be used for the t
34、est. The test specimens may be tested either with or without fire sleeves subject to agreement; identification ietter B for tests without fire sleeves, identification letter F for tests with fire sleeves. Prior to the test, the test specimens shall be stored at ambient temperature for 24 h. 5 Number
35、 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 each series shall be tested. 6 Testbench The tests shall be carried out on a test b

The test speci
37、mens shall be centred above the burner surface (see Figure 1). Dimensions in millimetres 20 min.

44、e duration of the test is 30 min. The duration starts at the moment the test specimen is exposed to the test temperature (flame temperature), which shall have been reached at both measuring points. NOTE 7.8 Proof pressure application Any deviating durations of test shall be agreed on. Following flam

46、f pressure after flame application. In the event of a test specimen failing, the test shall be repeated on two specimens of the nominal diameter having failed. If one specimen fails during the repeat test, the hose assembly of the design presented for testing will be regarded as having failed. If th
47、e test specimens pass the test successfully, the hose assembly of the design presented for testing will be approved, Le. from the smallest up to the largest nominal diameter of the series. 9 Test certificate The test results shall be certified in a test certificate as shown in the specimen in normat
