Class 5 indicator
Class 5 indicators are advanced instruments designed to monitor and verify the effectiveness of sterilization processes, particularly in steam autoclaves and ethylene oxide (EO) sterilization systems
These indicators ensure complete sterilization of medical devices by responding to a combination of process parameters, including temperature, time, and the presence of sterilizing gas
:Key Features of Class 5 Indicators
Sensitivity to Multiple Process Parameters: Class 5 indicators are designed to respond to a combination of sterilization process parameters
These parameters can include temperature, time, and sterilizing gas concentration
For example, in the ethylene oxide sterilization process, these indicators respond to a combination of temperature (55 to 65 degrees Celsius), time (about an hour), and gas concentration (600 mg/m3)
Visible color change: When exposed to appropriate sterilization conditions, the ink in the indicator changes color. For example, in the ethylene oxide sterilization process, the ink changes color from red to yellow, indicating that the process was successful
Documentation and traceability: Class 5 indicators can be used as documentation tools. By recording the color change results, it is possible to ensure that medical devices have been subjected to appropriate sterilization conditions
:Standards and recommendations
Based on international standards, such as ISO 11140, chemical indicators are divided into six classes. Class 5 indicators (Integrating Indicators) are known for their accuracy and sensitivity to a combination of sterilization process parameters.These indicators are commonly used in steam and ethylene oxide sterilization processes and can be embedded in sterilization packs to ensure the accuracy of the process
:Important points when using the Class 5 indicator
Indicator Location: To ensure complete penetration of the sterilizing gas, the indicator should be placed in the center of the package, where penetration may be more difficult
Interpretation of Results: Complete color change of the indicator indicates proper sterilization conditions. No color change may indicate problems in the process that need to be investigated and corrected
Combination with biological indicators: To further ensure the effectiveness of the sterilization process, it is recommended to combine Class 5 indicators with biological indicators. This combination can help in the final confirmation of the sterility of the equipment
The use of Class 5 chemical indicators helps improve quality and safety in sterilization processes and ensures the sterility of medical devices

:How to use the Class 5 Ethylene Oxide Indicator
Place the indicator: Place one indicator in each pack and place it in the center of the pack, where gas penetration may be more difficult
Carrying out the sterilization process: Sterilize the pack in an autoclave under standard conditions (gas concentration of 600 mg/cubic meter, humidity of 70%, temperature of 55 to 65 degrees Celsius, and time of one hour)
Checking the results: After the process is complete, make sure the indicator has changed from red to blue. If the color does not change, check the sterilization conditions and calibration of the device
