Sterilisation
Only previously cleaned and disinfected handles may be sterilised.
The handles are placed in a suitable sterilisation pack (one-way sterilisation pack, e.g. foil / paper sterili-
sation bags, single or double pack) in accordance with DIN EN 868 / ISO 11607 for steam sterilisation
and then sterilised.
Use only the sterilisation procedure listed below for sterilisation. Other sterilisation procedures (e.g.
ethylene oxide, formaldehyde and low-temperature plasma sterilisation) are not permissible.
Steam sterilisation procedure
Validated in accordance with DIN EN 554/ISO 11134
Maximum sterilisation temperature 134°C
Proof in principle of the handles’ suitability for effective sterilisation was provided using a fractional vacu-
um process (Euroselectomat 666 by MMM Münchner Medizin Mechanik GmbH, sterilising temperature
134°C, holding time 7 min.).
When applying other sterilization procedures, the suitability and effectiveness of the process must be
validated.
