Integrity 
The wall satisfied the integrity criteria for the 122 minute test duration. 
3.6 
Deflection Measurements 
The lateral deflections on the unexposed face at the positions shown in Figure 5 were 
measured using a theodolite and rule. The maximum measured deflection was 65 mm away 
from the furnace at three quarter height and mid width of the wall (deflection point B). The 
results are summarised in Table 1.
