The test layout should be such that participants should
be required to navigate correctly their way to a pre-designated exit
via at least four decision points including at least two cross-junctions
and at least one T-junction. It should not be possible to navigate
the correct route by remaining attached to one continuous wall. The
correct route should include the placement of a non-exit door within
2 to 3 m of the correct exit door. A non-exit door is a fail exit.
The total distance travelled over the correct route should be not
less than 25 m, with the distance between decision points being not
less than 5 m.
