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

ISO 15541:2016 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 document. 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.

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.

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 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 document 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.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment,

as well as information about ISO’s adherence to the World 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 the first edition (ISO 15541:1999), which has been technically

revised.

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 first 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.

ISO 15541:2016(E)
Introduction

The 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 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.

Tests carried out using the test bench specified in this document are intended to lead to results capable

of being reproduced.

1 Scope

This document 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 document.

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.

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.
