3.5. Programs for testing
The Bowie&Dick-Test is proofing the process for steam penetration of the sterilization good (mainly
for textiles or paper wrap). This test is implemented in vacuum option only. The test is normally for
medical use only! The test body for this test should be an usable test package only.
The vacuum test is implemented in vacuum option only. It can be used for testing the leakage rate of
the unit. For the normal use it is not necessary to run this test (implemented for service/maintenance).
The test should run if the chamber is cold! The chamber temperature should be not higher than 40°C
(otherwise it is impossible to start the test).
If the test result is “Incorrect” the unit should get a service /
maintenance! In that case you should not use the device until
qualified service stuff has checked the device!
3.6. Overview for predefined programs
All sterilization cycles are running automatically. The duration of a single cycle depends on the load,
kind of deaeration, number of vacuum fractions in fractionated pre-vacuum and the start conditions
(warm or cold), drying time, kind of cooling etc. Even so the type of sterilization goods and kind of
loading the good inside the chamber have an enormous effect on the cycle time. In case of a
validation you can define the goods and loads. When ever the same good / load with same program
and same parameters is started, the time depends mainly from start temperature. Basically, the
higher the mass of the load and the colder the items to be sterilized and the sterilization chamber, the
longer the time per cycle.
The table gives an overview for the different preselected programs:
