The work of preparing International Standards is normally carr

    19、ied out through IS0 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.

    20、IS0 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 ISOAEC Directives, Part 3. Draft International Standards adopted by the technical commit

    21、tees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 %ofthe member bodies casting a vote. International Standard IS0 15541 was prepared by Technical Committee ISOfC 8, Ships and marine technology, Subcommittee SC 3, Rping and

    22、machinery. Introduction The main objective ofthe test using the test bench 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 pres

    23、sure. 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 ofresistance to fire as recorded during the test will also occur in the event of an actual fire, as the conditions ofinstallation, which essentially

    24、 affect the duration of resistance to fire, may vary fkom case to case. Tests carried out using the test bench specified in this International Standard are intended to lead to results capable ofbeing reproduced. . 111 O BSI 21 September 2001 iv blank EN IS0 15541:2001 1 Scope This International Stan

    25、dard specifies requirements for a test bench to determine the fire resistance ofhose assemblies, in particular by tests according to IS0 15540, up to at least 100 mm nominal diameter. During the exposure to flames, there are possible working pressures up to 10 bar. The flame spread ability of the ho

    26、se 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 bed in the event of damage to the hose during the test, the use of combustible test media i

For dated references, subsequent amendments to, or revisions of, any ofthese publications do not apply. However, parti

    28、es to agreements based on this International Standard are encouraged to investigate the possibility ofapplying the most recent editions ofthe normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of IS0 and IEC maintain
