Individual registrations available too.
Routine EO processing requires controlled lifecycle validation evidence.
EO sterilization decisions affect sterile labeling, load release, process control, equipment qualification, and ongoing production readiness for heat-sensitive medical devices.
The session organizes ISO 11135 implementation across equipment qualification, product/load validation, software controls, sterile load evidence, and periodic revalidation planning.
This session follows the EO sterilization lifecycle from pre-conditioning, sterilization, and aeration through qualification, process variables, overkill methods, residual considerations, routing, storage, and revalidation. The structure connects ISO 11135 expectations with practical validation activities used before routine production and during continued process control.
- ISO 11135 requirements for EO sterilization validation
- EO equipment qualification, including IQ, OQ, MPQ, and PPQ
- Product, load, sterile load, BI, and PCD validation approaches
- Computerized controls and software verification for sterilization systems
- Critical EO variables affecting Sterility Assurance Level achievement
