10.1 Chemical integrators

These tests (spare code 200/S and 215-S) are based on the properties of indicator dyes
that are able to modify their own aspect if they are adequately exposed to heat and
pressure according to given times, since they interact with all the cycle parameters
(pressure, temperature, time). If the test is successfully completed, the correct stability is
validated.

10.2 Biological indicators

The test (spare code 262-S) is used to prove the autoclave capability as to the complete
destruction of all microorganisms.
It is represented by a standardized spore preparation, having biological characteristics,
high resistance to heat, which is to be deemed an absolutely safe control tool (ATCC
7953). It consists of spore ampoules. It is non pathogenic, non toxic and non pyrogenic.

AUTOCLAVE VALIDATION TESTS

The chemical integrators are to be put into the sterilization chamber
before starting the cycle, even with the load already in.
The integrators can either be unwrapped and positioned into the trays
or they can be wrapped into the sterilization bags together with the
materials to be sterilised.
In any case it is advisable to wrap the integrators where there are
many operators. As a matter of fact by doing so the sterilization of
every single tool will be certified.
There is no preset testing interval, apart from areas to which specific
regional regulations apply. In any case all the chemical integrators are
the cheapest and quickest available tests, hence in order to
constantly monitor the autoclave performance, it is advisable to use
them on all of the cycles or at least once a day.
