Aborted sterilization process

If a sterilization process has been aborted, it may be still possible that a Bowie-DickSimulation-Test, a batch monitoring system or a package indicator show still successful colour change, even if the plateau period of the sterilization time did not run completely through.


All chemical indicators for steam sterilization processes should change only to the final colour, if condensing steam is present and the temperature-time-integral (F0-value is achieved during the process. Typical temperature-times in steam sterilization are listed below:

A colour change to the end point must not occur during this time
A colour change to the end point shall have occured after this time
