It is proposed to discuss a general method for sizing the safety devices, for cryogenic fluids and whatever the thermodynamic states. In particular the interesting case of the two-phase subcritical discharge will be addressed. The calculation is separated in three operations:

o The estimation of the loads arriving on the component to protect,

o The calculation of the mass flow to evacuate,

o And the sizing of the safety device..
