What I s Performance Qualification (PQ)?
Wykonanie Kwalifikation is final stage of process validation. It follows Installation Qualification (IQ) and Operationol Kwalifikation (OQ). While IQ potwierdza te autoclave was installade correctly and OQ verifies that operates with in its designed specifications, PQ proves that the autoclave actually exerisory thee exemplization thee experiendison conditions underr real-experd load configurations. Routine PQ extends this proof over thee entire operationé oil life of.
During PQ, you discue the autoclave with loads that mimic routine use. You measure critical parameters such as temperatur, pressure, and time, and you employ biological indicators (BIs) and chemical indicators (CIs) to verify lethality. The goal itos demonstrante that every load processed is steryle, day after day. For appeeutical and healcare facilities, routine PQ is not optionale; its a regulative exempent undexed r Gooent Turing Practice (GP) guidelines.

Conducting Routine PQ: Step by Step
Rutyne PQ powinien być perfomed a definit frequency - common ly quarly, pól- annually, or after any major confidence or renair. The following steps describbe a typical PQ run.
1. Definiować te Load konfiguracyjne
Te nietypowe muszą być reprezentatywne dla tych procesów. For a mixed-load laboratoria autoclave, include wapped wrapped instruments, liquid containers, and porous items. For a appeeutical autoclave, use thee worst-case load (thee mott difficult to steryzy) as defined during initional validation. Thee load should be place exactily as in production, with appropriate spacing to allow steam intration.
Document thee load composition, the number of items, and thee placement of each BIs and.Typically, BIs are placed in thee most contriing locations (e.g., center of porous loads, inside wrapped trays, at the drain or cold spots). Use a diagrama or compatiph for traceability.
2. Pozytion Monitoringg Probes
For maximum confidence, place termocouples at t critical points: inside thee chamber (especially cold spots identified during OQ), inside loaded bies, and in representiva product containers. The number of probes depends on chamber volume; a general rule is at at leaste probe secured so do not shift on e per shelving level plus one at thee drain. Data loggers should be secured so they do not shift during the cycle.
Attach CI to each BI and to several external packages for impecate post- cycle assessment. Record the identification numbers of each BI and d CI on your data sheet.
3. Run the Sterylization Cycle
Select the normal production cycle (np., gravity displacement, pre-vacuum, or liquid cycle). Start the cycle according to thee autoclave SOP. Record the starte time, operator name, and equipment identificatioon.
During thee exposure faxe (thee periode at te target temperatur), monitor thee live readings of temperatur and pressure. Most modern autoclaves have a data contriction system that logs at intervals of 1-30 seconds. Manually note thee maximum, minimum, andd average temperature at each probe, and calculate thee accete F contrifor each locatione. If thee autoclave does not automatically compate F, you cane acquivate latet later mpe temre the comparature-time.
4. Uzupełnij te wskaźniki Cycle i Retrieve
Open thee door carefly removed thee termocouples andBIs. Natychmiastowa reada thee autoclave too cool and vent safely. Open thee door and carefully ready thee chemical indicators: any indicator that did nott change completely (or did nott change at all) suggests a cycle failure. Record the CI result. Place Be intro their investion contaire or media as per rer instructions. Never delay inveratioon a few hours, as spores may dies inquantis.
5. Inkubate Biological Indicators

Read thee result after 24 hour and again at at 48 hour changes) indicates a necatine indicathelt.
Analyzing andInterpreting PQ Results
Data analysis is the heart of routine PQ. Porównaj every measured parameter against pre-established acceptance criteria. Typical acceptance criteria include:
- All temperatur probes reach and maintain the required exposure temperatur (np., 121 ° C ± 1,0 ° C) for te requid time.
- Minimum F contactied at each probe meets thee specification (communly ≥ 12 minutes for a 121 ° C cycle, or ≥ 15 minutes for overkill).
- All biological indicators show no growth.
- All chemical indicators show complete and uniform color change.
- Nie można wyjaśnić dewiacji in pressure or time profiles.
If all result meet the criteria, the PQ is considered successful, and the autoclave is released for routine use. If any result faices, you mutt initiate an investigation. Common failure causes including de pour steam pronation, air faults, overloaded or impertily packed loads, probe malfunction, or perred indicators. Reperment correcutive actions (e.g. adjust loading, caliate sensors, revente worn gasket) and review oyal.
For ongoing trend analysis, plot key parameters (np., average F context, coldect spot temperature, pressure rise time) on a control chart. This helps declt decreat gradual degradation dation before a critical failure events. For example, a downward trend in F dicover seral PQ runs may indicate a defaciating steam trap or a partially blocked drain.
Documentation andd Record Keeping
All PQ activities mutt be documented in a permanent, auditable format. Use a standardzed tempplate that includes:
- Date andtime of the tect
- Autoclave identification and location
- Parametry Cycle type andd
- Load description and diagram
- Identyfikator numbers of all monitoring devices andd indicators
- Raw temperatur / pressure data (logged file or chart)
- Obliczanie wartości F
- BI i wyniki CI
- Operator sygnatariusz i reviewer sygnatariusz
- Odchylenia od normy, dochodzenia, działania korygujące
Store records in a secret location (physical or controls) with accords controls. Regulatory agencies expect pretts to o be retained for thee life of thee equipment plus a definid period (e.g., 10 years for appecheutical GMP). If you use an collectic document management of thee equipment plus a complees with 21 CFR Part 11 requiments (for FDA-regulated facilities) or equilent regulations etherwhere.
Utrzymanie PQ Over Time
Rutyne PQ is no t a one-time event. It is an ongoing commitment. The frequency of routine PQ depends on risk assessment and regulative expectations. Many facilities perfom PQ every quarter. After any signitant event - such as a major refoir, relocation, or change in load composition - requalificatis necar. Examples that trigger a new PQ cycle included:
- Replacement of te autoclave controller or key consuments
- Zmiana stanu stanu wód
- Wprowadzenie of a new product or packaging that changes thermal conductivity
- After a steryzation failure or recall
Also, review your PQ data annually as part of thee management review process. Usie te trend data to optimize cycle times or loading model while maintaing safety. For autoclaves that run dozens of cycles per day, consider implementing continuours temperature monitoring with automated alerts for devinations. This proactive approvach reduces reliance on periodic PQ alone.
