Vacuum test
CAUTION! Follow local/national guidelines on the frequency of testing.
Notice: If a drainage period of the S Fast 134 cycle is still operating, wait the drainage to be finished and the sterilizer to be both cold and dry.
Otherwise, a false negative outcome could occur.
PURPOSE OF THE TEST
The test is used to validate the sterilizer performance in terms of:
n
efficiency of the vacuum pump
n
tightness of the pneumatic circuit
DESCRIPTION
It consists of a vacuum phase, followed by a stabilization period of 5 minutes and a testing period of 10 minutes. The internal pressure is
monitored during the testing period. The pressure rise must be less than 0.013 bar (0.19 psi).
CARRY OUT THE TEST
1
Empty the sterilizer chamber to ensure no load is present.
2
Close the chamber door and ensure the sterilizer chamber is completely dry and
cold to avoid any false negative outcome.
