How to calculate equilibration time

Validation
1

Dear all,

In autoclave, I am keeping Sterilization Hold start temperature at 121.7, in that scenario what is the temperature in first probe to calculate the equilibrium time. Please give me reference also if possible.
I am waiting for your valuable suggestions.

Thanks and regards,
Ratna raju.

Hi,

The set temperature will achieve to equilibrium with all the probes in short time. The time at which the set temperature reaches equilibrium the hold time starts. It is generally set at above 121. In modern autoclave the holding time automatically starts once the equilibrium is achieved and this is validated frequently.

Dear ratna raju,

Sterlization temperature reaches First probe to last probe achive time is a equilibrium time

Limits: below 800 lts 15 sec
above 800 lts 30sec is limit Refer HTM 2010 Part-3
