For this article, the general requirements for an overkill cycle PQ will be reviewed.

While many activities are required to complete the PQ, the primary goal for the commonly employed overkill validation is this: the user needs to complete three consecutive successful halfcycles in order to qualify their proposed fullcycle exposure for routine processing of sterilization loads.

It should be noted that at the time this article was prepared, the proposed guidance document that is to accompany ISO 17665-1 was not yet available.

This guidance document may provide more advice on microbiological qualification issues (ISO 17665-2 Sterilization of health care products — Moist heat — Part 2: Guidance on the application of ISO 17665-1).

In our case, successful means all BIs are killed (no growth upon incubation) for the three consecutive halfcycles.

Validation protocols vary in format from company to company, but most will capture similar information for the final report.Much of this type of information would be recorded in well-written validation protocols or validation final reports.Biological indicators often use spores of the bacterial species Geobacillus stearothermophilus at a titer of greater than 106per BI, although other species or titers are sometimes used.The sterilizer must be installed in such a manner to facilitate any necessary maintenance, repair, adjustment, cleaning,and calibration.OQ is defined as “obtaining and documenting evidence that the installed equipment operates within predetermined limits when used in accordance with its operational procedures.” Autoclave OQs commonly test or verify items such as cycle operation and programming instructions, safety and alarm testing,error reporting, empty chamber temperature profiling and chamber temperature limits/specifications, air removal testing, leak testing, temperature control anomalies, full cycle full-load temperature profiles (if proposed fullcycle exposure time is known), and determination of any hot or cold spots withinthe chamber.
