The work of preparing International Standards is normally carried o
11、ut 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 c
12、ollaborates 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 app
13、roval 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
14、subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

16、on (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 (
17、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 th
18、e 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 reservedBS ISO 15541:2016ISO 15541:2016(E)IntroductionThe main objective of the test using the test
19、 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 a
20、s 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
21、case to case.Tests carried out using the test bench specified in this document are intended to lead to results capable of being reproduced.

22、pensators Requirements for the test bench1 ScopeThis 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 conditio
23、ns 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
24、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.2 Normative referencesThe following documents are referred to in the
