Important information about routine operation
Please follow the current recommendations from the Robert Koch Institute (RKI) and the directions in DIN
58946-7 regarding routine operation.
Manufacturer's recommendation for routine operation of class B
autoclaves
(in accordance with the current recommendations from the Robert Koch Institute)
When does testing need to
be done?
Once a working day
Once a week
Batch-related tests
WARNING
The results of the tests must be documented.
The used indicator test strips themselves do not have to be stored.
How is testing done?
Visual inspection of the door seal and the door closure for any
leaks.
Inspection of the operating media (electricity, feed water, water
connection where applicable).
Inspection of the documentation media (printer paper / computer /
network).
The steam penetration test with the Bowie - Dick test in the universal
program is recommended (test system in accordance with EN 867-5).
Vacuum test
Tip: In the mornings before starting work—the autoclave must be cold
and dry.
For instruments in Critical B category:
the test set Helix test should be done together with every
sterilization cycle as a batch control.
For instruments in Critical A category:
a chemical indicator (class 5 as defined by ISO 11140) should be
included together with every sterilization cycle as a batch control.
For instruments in Critical A+B category:
The test set Helix test should be done together with every
sterilization cycle as a batch control.
This simplifies the workflow and increases the reliability. A daily steam
penetration test with the Bowie & Dick test (see above) can then be
omitted.
Another test system as defined by EN 867-5 can be used. Due to the
variety of test systems available, it is not possible for Sirona to provide
technical support for the use of another system.
