Table 4

Variation of internal pressures due to material uncertainty under SSC (MPa).

Limit states	Uncertainty	Pressure only	200°C	400°C	600°C
Onset of leakage	Lower bound level	0.975	1.09	1.24	0.13
	Upper bound level		1.08	1.22	0.13
Functional failure	Lower bound level	1.287	1.39	1.43	1.35
	Upper bound level		1.37	1.40	1.32
