particular:
- the efficiency of the preliminary vacuum and the penetration of steam within the cavities
- the temperature and pressure values of the saturated steam during the sterilization phase
The packet for the B&D test must be inserted on its own, preferably on the lowest tray, with the label facing
up. After performing the cycle, specifically the B134 cycle, immediately verify the test. Being careful while
handling the packet (it is still hot), remove the indicator sheet and follow the instructions given in the package
for evaluating the result of the test.
Helix test
The Helix test represents a hollow A-type load, i.e. the load with the most critical characteristics.
The test consists of a 150 mm long PTFE tube with a 2 mm internal diameter.
The Helix test simulates the performance of the unit with respect to the sterilization of hollow loads, in
particular:
- the efficiency of the preliminary vacuum and the penetration of steam within the cavities
- the temperature and pressure values of the saturated steam during the sterilization phase
