Annex 6 VACUUM TEST
This test is used to validate the performance of the sterilizer in terms of leakage:
 The efficiency of the vacuum pump.
 The tightness of the pneumatic circuit.
The profile of the cycle, specific for this test includes:
 A vacuum phase up to P1 = - 0.85 bar.
 A stabilisation period of 5' => T2. Reading of P2.
 A testing period of 16' => T3. Reading of P3.
Carry out the test as follows:
♦ Select and start the Vacuum Test cycle from the "service" sub-menu.
♦ The micro-processor makes the following calculation: P3 - P2. The result must be less than 0.02 bar *.
♦ Comments, positive or negative are displayed at the end of the test.
* IMPORTANT : According EN13060 norm, the " AIR LEAKAGE / VACUUM TEST " requires a 13mbar (0,013bar) leak test
within a period of 10min. that is to say 1,3 mbar/min. The sterilizer pressure sensor is not 1mbar
(0.001bar) but 10mbar (0.01bar) accurate. A leak of 13mbar is therefore not measurable but only a
20mbar (0,02bar) one. The test period has proportionally been increased from 10 to 16min. so that a
leak test of 20mbar within 16min. that is to say 1,25 mbar/min is proven.
