ISO 15541 pdf download.Ships and marine technology — Fire resistance of hose assemblies — Requirements for the test bench 1 Scope This International Standard specifies requirements for a test bench to determine the fire resistance of hose assemblies, in particular by tests according to ISO 1 5540, up to at least 1 00 mm nominal diameter. During the exposure to flames, there are possible working pressures up to 1 0 bar. The flame spread ability of the hose 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 is excluded. 2 Normative reference(s) The following normative documents contain provisions that, through reference in this text, constitute provisions of this International Standard.
