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.
