Note: This UI FTP 1 is to be uniformly implemented by IACS Members and Associates from 1 January 2001. FTP 1 (June 2000) FTP2 Pipe and duct penetrations (para. 5.1 of Res A.754) In cases where a test specimen (deck) which includes the prototype penetration(s) is not mounted within a rigid restraint frame but is connected to the furnace roof by side wall coamings, the rigidity of the coamings is to be equivalent to that of a restraint frame and evaluated in accordance with Section 5.1 of A.754(18). In cases where insulation is fitted to the test pipe(s), the distance(s) of 500 ±50 mm required in A.III/2.2.3 of A.754 to which the pipe should project is to be taken from the end of the insulation as this is considered an integral part of the penetration(s) being tested and it is necessary that a length of unprotected pipe is exposed to the furnace. In all cases, the support and fixing of the test pipe(s) is to be by a framework mounted from the restraint frame such that any movement of the bulkhead or deck relative to the pipe(s) will be experienced by the penetration(s) being tested. Note: This UI FTP 2 is to be uniformly implemented by IACS Members and Associates from 1 January 2001. FTP 2 (June 2000) IACS Int. 2000 Fire Door FTP Code sub-section 5.3 and Annex 1, Part 3 Test for “A”, “B”, and “F” class divisions Paragraph 2.1, paragraphs 2.3.1 and 2.6.1 of resolution A.754(18) Interpretation A fire door of larger dimensions than a fire tested fire door may be individually assessed and accepted for a specific project with the same classification provided: Dimensions (width, height) are not more than 15% above those of the tested door. The surface area of the door is not more than 10% above that of the tested door. The door design does not deviate in any other aspect from the one tested. The results of the original fire test give comfortable margins. Larger doors would need to be tested or calculated. Note: This UI is to be uniformly implemented by IACS Members and Associates to ships keel laid from 1 July 2005. IACS Int. 2004 FTP 3 (Dec 2004) FTP 3 END FTP 4 Fire resistant windows on tankers (Appendix A.I to resolution A.754(18) Regulation Paragraph 2.2 of Appendix A.I to resolution A.754(18) reads: 2.2 Design The bulkhead which includes the window should be insulated to class A-60 on the stiffened face, which should be the face exposed to the heating conditions of the test. This is considered to be most typical of the use of windows on board ships, not necessarily being the worst way around. There may be special applications of windows where the Administration considers it appropriate to test the window with the insulation of the bulkhead to the unexposed face of the structural core, or within bulkheads other than class A-60. The window should be positioned within the bulkhead, shown in figure 1 of the resolution, at that height which is intended for practical application. When this is not known, the window should be positioned with the top of its frame as close as possible, but not closer than 300 mm, to the top of the bulkhead. Interpretation Windows to be fitted at the forward bulkhead of accommodation block on tankers shall correspond to prototype subject to the “A” class standard fire test with the fire against its external side (i.e. the side which, after the installation on board, will be exposed to the weather). The insulation of the bulkhead used along with the windows specimen shall be fitted on the unexposed face of the structural core. Note: This UI is to be uniformly implemented by IACS Members and Associates to ships constructed on or after 1 January 2007. IACS Int. 2005 FTP 4 (Sep 2005) FTP 4
