1 Non-combustible material is a
material which neither burns nor gives off flammable vapours in sufficient
quantity for self-ignition when heated to approximately 750 °C, this being
determined by a fire test in accordance with the IMO Resolution A.799 (19)
"Revised recommendation on test methods for qualifying marine construction
materials as non-combustible". Any other material is a combustible material..
1.a FOR B, C AND D SHIPS, CONSTRUCTED ON OR
AFTER 1 JANUARY 2003:
Non-combustible material is a material which neither
burns nor gives off flammable vapours in sufficient quantity for self-ignition
when heated to approximately 750 °C, this being determined in accordance with
the Fire Test Procedures Code. Any other material is a combustible material.
.2 A standard fire test is one in
which specimens of the relevant bulkheads or decks are exposed in a test
furnace to temperatures corresponding approximately to the standard
time-temperature curve. The specimen shall have an exposed surface of not less
than 4,65 m2 and height (or length of deck) of 2,44 metres, resembling as
closely as possible the intended construction and including where appropriate
at least one joint. The standard time-temperature curve is defined by a smooth
curve drawn through the following internal furnace temperature points:
initial internal furnace temperature | 20
°C |
at the end of the first 5 minutes:
| 576
°C |
at the end of 10 minutes: | 679 °C |
at the end of 15 minutes:
