Refractoriness Under Load (RUL; differential - with rising temperature)
The graph shows the result of an RUL test on a test piece taken from a fireclay brick (approx. 35% Al₂O₃);
Test conditions: 0.2 N/mm2; 5 K/min; static air.
At 960°C the test piece reaches its maximum expansion. Deformations of 0.5%, 1.0% and 2.0% have been achieved at 1210°C (T05), 1240°C (T1), and 1270°C (T2) respectively.

Creep In Compression (CIC)
A CIC test was performed on a test piece taken from a fireclay brick (approx. 35% Al₂O₃);
Test conditions: 0.2 N/mm2; 5 K/min; 25h at 1190°C; static air.
The double graph shows the dynamic heating phase and the time-scaled creep at constant temperature.
