It is important to periodically verify the performance of the unit by performing the appropriate tests;
E9 can perform three different ones:
- B&D test
- Vacuum test
- Helix test
The parameters of the respective cycles are as follows:
Vacuum test
The sole purpose of the diagram is to illustrate the quality performance of the cycle
This test is performed in order to check the performance of the unit, in particular:
- the efficiency of the vacuum pump;
- the seal of the hydraulic circuit.
The cycle is structured as follows:
1. a vacuum is created to the minimum pressure value indicated in the load pre-treatment phase
2. this pressure is maintained for 5 minutes and then measured
3. this pressure is maintained for 11 minutes and then measured
In compliance with EN13060, the test requires a tightness test of less than or equal to 1.3 mbar/min during
the 10 minutes of test; if the leakage is greater than this value, the outcome of the test is negative; the seal
of the hydraulic circuit of the device must be checked.
Bowie & Dick test
This is a chemical-physical test that is also known as the Brown test: the indicator is a heat-sensitive sheet
that is placed in the middle of a packet made up of various layers of paper and foam rubber.
The B&D test simulates the performance of the unit with regard to the sterilization of porous loads, in
