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:

at
the end of 15 minutes: | 738 °C |
at the end of 30 minutes: | 841
°C |
