(1)
Only a few hours, with little or no load applied
-
(2)
After these periods mechanical properties reduce by approx 50%.
Note, however, that service temperatures are load and time
dependant.
-
(3)
Test specimen 1.6mm thick unless otherwise stated.
-
'A'
No attack
-
'B'
Mild attack by absorption
-
'C'
Dimensional change due to absorption
-
'D'
Decomposition in short time
-
'E'
In steam - at 160°C, decomposition after short time
