5 Fuel packages
5.1 Ignition package
Ignition package, consisting of a square tray of internal dimensions 300 mm × 300 mm × 100 mm deep,
made from 12 gauge steel containing 200 ml of commercial grade heptane floated on water of 25 mm
minimum depth.
A wood crib consisting of 8 layers of wood sticks of Pinus silvestris, with 4 sticks per layer spaced 50 mm
apart, shall be placed on top of the steel tray. An optional lip can be added to the steel tray to provide
stability to the crib. The wood sticks shall be 38 mm × 38 mm cross-section by 305 mm long (actual) and
plane finish. The complete wood crib shall have the nominal dimensions of 305 mm × 305 mm × 305 mm
and shall weigh (8 250 ± 250) g (see Figure 1 and Figure 2).
Two cotton wicks, each 250 mm long, soaked in 100 ml of heptane, of which 150 mm of each wick, shall
be placed on a fire brick and laid along the edge of the foam sheets with the remaining 100 mm exposed.
5.2 Fuel package
Fuel package, consisting of 2 sheets of non-fire resisting polyether foam 775 mm × 865 mm × 75 mm,
having a density of 20 kg/m. Each sheet shall be glued to a sacrificial backing board,
775 mm × 865 mm × 12 mm, which is attached to a wooden supporting frame (see Figure 1 and
Figure 2). The foam sheets shall be flush with the top and sides of the sacrificial board and frame.
5.3 Plywood panels
For the corner tests, two walls shall be covered, floor to ceiling, by 12 mm thick plywood panels covering
(2,4 ± 0,1) m in length (see Figure 3, Figure 8 and Figure 9). The distance of the ignition and fuel package
from the plywood panels walls shall be controlled to (50 ± 5) mm (see Figure 1).
For the centre tests, a partition arrangement of plywood panels shall be used, made from two 12 mm
thick plywood panels each (2,2 ± 0,1) m in length and 1,2 m in height (see Figure 4, Figure 5 and
Figure 10). The panels should be constructed so that there is no air gap between them.
The distance of the ignition and fuel package from the plywood partitions shall be controlled to
(50 ± 5) mm (see Figure 2).
