This Part of BS3970 specifies particular requirements for sterilizers intended to be used for the sterilization of aqueous fluids in sealed rigid containers in which the heat transfer is effected by saturated steam under phase-boundary conditions, having a steady-state equilibrium during the holding phase. These requirements apply in addition to the general requirements specified in BS3970-1.
NOTE1 Recommendations for the information to be supplied by the purchaser to the manufacturer are given in Appendix A.
NOTE2 The attention of both the sterilizer manufacturer and the user is drawn to the hazards associated with processing fluids in sealed rigid containers described in Appendix H.
