Annex 5 HELIX TEST
The Helix Test is the most complex representation of a hollow instrument load ( type A ).
Characteristics:
Length: 150 cm Strip test
Internal diameter: 2 mm
Material : PTFE
This test is used to validate the equipment performance in terms of hollow instruments sterilization, namely:
 Pre-vacuum efficiency, rapid and uniform steam penetration.
 Temperature and pressure parameters of saturated steam during the holding time.
The cycle profile is identical to that of other cycles with:
 a temperature of 135,5°C
 a pressure of 2,16 bar.
 a sterilization plateau of 3 min 20 sec. guaranteeing a
security margin.
 a drying time cut to 4 min not to falsify the result.
Carry out the test as follows:
♦ Place a test strip inside the capsule.
♦ Close the capsule.
♦ Place the test on the lower tray in the chamber.
♦ Select and start the Helix / B&D cycle from the "service" under-menu.
♦ Once the cycle is competed, open the door and remove the test.
Caution the Helix Test will be very hot !
♦ Open the capsule and remove the test strip.
Correct result: Incorrect result:
The 4 spots on the strip have turned black . Not all the spots have turned black.
