The work of preparing International Standards is n
11、ormally carried out through ISO 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, governmental and non-governmental, in liaison with ISO, also take part i
12、n the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular
13、the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this doc
14、ument may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.o

16、 Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following URL: www.iso.org/iso/foreword.html.The committee responsible for this document is ISO/TC 8, Ships and marine technology, Subcommittee SC 3, Piping and machinery.This second edition cancels and replaces th
17、e first edition (ISO 15540:1999), which has been technically revised. It also incorporates the Technical Corrigendum ISO 15540:1999/Cor 1:1999.The most significant change in this second edition is the inclusion of non-metallic compensators to the fire test procedures outlined in this document. The f
18、irst edition of this document applied primarily to non-metallic hose assemblies. Because the compensators are used in common piping systems and may have similar materials to hose assemblies, the applicability of the test procedures was expanded to include compensators.iv ISO 2016 All rights reserved
19、BS ISO 15540:2016ISO 15540:2016(E)IntroductionThe main objective of the test using the test bench described in this document is to determine whether and for a safety period a non-metallic hose (made of rubber) assembly or non-metallic compensator (bellow made of rubber) can be exposed to fire withou
20、t becoming inoperable when subjected to the design working pressure. Although the attacking fire is simulated such that it corresponds to a fire occurring in practice, it cannot be assumed that the duration of fire resistance as recorded during that test will also occur in the event of an actual fir
21、e, as the installation conditions, which greatly affect to the duration of fire resistance, may vary from case to case.When carried out using the test bench specified in ISO 15541, the test procedure according to this document is intended to lead to results capable of being reproduced by testing the
22、 same size and type.A specimen test certificate is specified in Annex A. ISO 2016 All rights reserved vBS ISO 15540:2016BS ISO 15540:2016Ships and marine technology Fire resistance of non-metallic hose assemblies and non-metallic compensators Test methods1 ScopeThis document specifies a test procedu
23、re for determining the fire resistance of non-metallic hose assemblies and non-metallic compensators with nominal diameter of up to 150 mm. It may be used for larger sizes provided proper test bench conditions are obtained.It serves for proving whether, after the period of fire effect on the test be
24、nch specified in ISO 15541, hose assemblies and non-metallic compensators 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 personnel and the test bench in the event of damage to the hos
25、e or non-metallic compensator during the test, the use of combustible test media is excluded.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

30、ngth of a least 500 mm shall be used as test specimen.Each series of non-metallic compensators which have the same shape and identical construction shall be tested in their standard configuration.The purchaser and operator of the test bench shall agree which fitting types shall be used for the test.
31、The test specimen may be tested either with or without fire sleeves subject to agreement; identification letter B for test without fire sleeves, identification letter F for tests with fire sleeves. If fire sleeves are used, then all specimens qualifying a series of non-metallic hose or non-metallic
32、compensator shall be tested with fire sleeves.Prior to the test, the test specimen shall be stored at ambient temperature for 24 h.6 Number of test specimenThe type tests shall be carried out on a minimum of three non-metallic hose assemblies or non-metallic compensators with different nominal diame
33、ters of up to 150 mm but of identical hose or compensator construction. The smallest, the middle and the largest nominal diameter of each series shall be tested.For an approval of non-metallic compensators with size range above 150 mm one additional test with half of the biggest size shall be tested
34、.7 Test benchThe test shall be carried out on a test bench according to ISO 15541.8 Test performance8.1 Installation of test specimenThe test specimen shall be installed on the test bench such that the burner end extends beyond one hose end fitting by at least 20 mm such that the fitting and hose is
35、 completely enclosed by the flames (see Figure 1).In case of non-metallic compensators, the specimen shall be arranged such that the bellow (or other compensator design shape) and both end fittings or flanges are parallel to the surface of the burner and are completely enclosed by the flames.The tes
36、t specimen shall be centred above the burner surface (see Figure 1) in order to provide a flame appearance according to ISO 15541:2016, Annex A, Figures A.1 and A.2.2 ISO 2016 All rights reservedBS ISO 15540:2016ISO 15540:2016(E)Dimensions in millimetres1223Key1 test specimen2 burner3 burner widthFi

39、acuate as far as possible the air contained in the test specimen.8.4 Measured values and measuring pointsThe following measured values shall be determined at the measuring points indicated in Figure 2: water temperature at measuring points 1 and 2; flame temperature at measuring points 3 and 4; flow

43、of at least (5 0,2) bar or the maximum allowable working pressure (M.A.W.P.) as identified on the product.Any deviating working pressure shall be agreed on.8.7 Duration of testThe duration of the test is 30 min. The duration starts at the moment the test specimen is exposed to the minimum test tempe
44、rature (flame temperature), which shall have been reached at both measuring points.In case of non-metallic compensators, a leakage of the flange connection during or at the end of the flame application may be one-time corrected by retightening the flange screws. The flame impingement duration is to
45、be extended accordingly. The nominal length of the compensator has to be fixed during the test to avoid additional stress on the bellow due to uncontrolled elongation.4 ISO 2016 All rights reservedBS ISO 15540:2016ISO 15540:2016(E)Any deviating durations of test shall be agreed on.8.8 Proof pressure
46、 applicationFollowing flame application, the test specimen shall be subjected at ambient temperature to proof pressure for 2 min duration as follows:a) hose assemblies: proof pressure according to applicable hose standard, normally two times the M. A .W.P.b) compensators: proof pressure is 1,5 times
47、 the M.A.W.P. The proof pressure application can be omitted in case the test specimens have been subjected to the M.A.W.P. during flame application.9 AssessmentThe test is considered as passed when the test specimen remains tight when subjected to proof pressure after flame application.In the event
48、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 the test specimens pass the test successfully, the h
49、ose assembly and compensator of the design presented for testing will be approved, i.e. from the smallest up to the largest nominal diameter of the series.10 Type test certificateThe test results shall be certified in a test certificate as shown in the specimen in Annex A.
