Which factor is NOT part of the autoclave sterilization process as described?

• A. Color
• B. Time
• C. Temperature
• D. Pressure

Answer: (A)

Autoclave sterilization relies on saturated steam under pressure to reach temperatures high enough to destroy microorganisms. The three factors that determine whether sterilization is achieved are temperature, exposure time, and pressure; they work together so that heat penetrates all items and kills even resistant spores. Higher temperatures kill faster, but you need the right duration to ensure complete sterilization, and pressure is what maintains that high temperature and drives steam into wrapped or densely packed loads. Color of the items or packaging has no effect on sterilization performance, so it is not part of the process.
