The Importance of Steam Quality Tests (SQT)
Steam Quality Tests (SQT) are crucial for ensuring the effectiveness of saturated steam sterilization processes. The quality of the steam used directly impacts the safety and efficacy of sterilization.

Key Steam Quality Parameters
The main parameters evaluated in steam quality tests are:
  • Non-condensable Gases: The volume of non-condensable gases in the steam should not exceed 3.5%. These gases (such as oxygen, nitrogen, CO2, etc.) can reduce sterilization effectiveness by preventing steam from reaching all surfaces of the load. Contrary to common belief, non-condensable gases tend to accumulate at the bottom of the autoclave chamber because they are heavier than water vapor.
  • Superheat: Steam should not be superheated by more than 25°C above the saturation temperature. Superheated steam decreases sterilization effectiveness.
  • Dryness: The dryness value of the steam should be at least 0.9 (90%) for metal loads and at least 0.95 (95%) for porous loads. Excessively wet steam can cause condensation on the load, reducing sterilization effectiveness.
The EN 285 standard sets the requirements for verifying these parameters, ensuring that every sterilization process meets high standards.

Our Approach
Our dedicated qualification team regularly performs these tests, ensuring continuous monitoring and maintaining the highest levels of safety and compliance.

Conclusion
Regularly conducting SQT is essential to maintain sterilization effectiveness and protect patients.
