183.590 - Fire test
(e) If a fuel tank is being tested in
an actual or simulated hull section, the actual or simulated
hull section must be of sufficient size to contain enough
heptane to burn for 2 and 1/2 minutes in a place adjacent
to the tank.
|
An actual or simulated hull section must duplicate
the configuration from which the tank was removed or is intended
to be installed. Figure 49 shows typical test setups using
simulated hull sections.
Just as with other components of the fuel system,
the test tank, filled to no more than quarter of its listed
capacity with fuel, must withstand the 2-1/2 minute fire test.
There are no temperature requirements for this test as the
temperature achieved depends on the configuration of the hull
section and the distribution of the fuel in this hull section.
The hull section must be arranged so there will be enough
fuel to burn for 2-1/2 minutes, even if a special dam is necessary
to hold the fuel.
FIGURE
49 - Fuel Tank Fire Test in a Simulated Hull Section
The fuel tank is subjected to a fire test.
The tank being tested here is supported by structure to replicate
the actual installation in a boat. A dam has been built to
contain the heptane fuel during the test.
