Chapter 4 – Sterilizing

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.
