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 2.

The main task of technical committees is to prepare International Standards. 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.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 15541 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee
SC 3, Piping and machinery.

Introduction

The main objective of the test using the test bench described in this International Standard is to determine
whether and for a safety period a non-metallic hose assembly or non-metallic compensator can be exposed to
fire, without becoming inoperable, 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 that test will also occur in the event of an actual fire, as the
conditions of installation, which essentially affect to the duration of resistance to fire, may vary from case to
case.

Test carried out using the test bench specified in this International Standard are intended to lead to results
capable of being reproduced.

DRAFT INTERNATIONAL STANDARD ISO/DIS 15541






Ships and marine technology — Fire resistance of non-metallic
hose assemblies and non-metallic compensators —
Requirements for the test bench


1 Scope

This International Standard specifies requirements for a test bench to determine the fire resistance of non-
metallic hose assemblies and non-metallic compensators with nominal diameter up to 150 mm. It may be
used for bigger sizes provided proper test bench conditions are obtained. During the exposure to flames, there
are possible working pressures of up to 16 bar.

The flame spread ability of non-metallic hose assemblies or non-metallic compensators cannot be tested with
the test bench specified in this International Standard.

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 of the non-metallic hose assembly or non-metallic
compensator during the test, the use of combustible test media is excluded.
