Foreword
ISO (the International Organization for 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 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.
International Standards are drafted in accordance with the rules given in the ISO/IEC 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 the member bodies casting a vote.
International Standard ISO 15540 was prepared by Technical Committee ISO/TC 8, Ships and marine technology,
Subcommittee SC 3, Piping and machinery.
Annex A forms a normative part of this International Standard.

Introduction
The main objective 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 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 case to case.
When carried out using the test bench specified in ISO 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.

Ships and marine 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 of at least 100 mm.
It serves for proving whether, after the period of fire effect on the test bench specified in ISO 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 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 normative document contains provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
publications do not apply. 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. For
undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC
maintain registers of currently valid International Standards.

bench.
3 Designation
The designation of the test for determining the fire resistance is composed of the elements quoted in the example
below:

ISO 15540:1999(E)
4 Test specimen and specimen preparation
Hose assemblies with a hose length of at least 500 mm shall be used as test specimens.
The orderer and 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 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 each series shall be tested.
6 Test bench
The tests shall be carried out on a test bench according to ISO 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 that the fitting is completely enclosed by the flames (see Figure 1).
The test specimens shall be centred above the burner surface (see Figure 1).
