Dear All,
What are the revalidation test conducted for sterilizers (laboratory Autoclave)?
And how many times different loads (garments, SS, Fluid, disinfectant) should be repeated during revalidation?


the re-validation tests conducted to the re-validation of autoclave are:pressure leak test,vacuum leak test,Bowei Dick test,vent filter sterilization test and finally one heat penetration study for each concerned load with Biological indicator challenge

Thank you Mr. Ahmed,
Just for reference, could you please provide the guideline reference of these test to be conducted,
