Sterilisation Bands

Sterilisation guidance documents reference known temperature bands used in decontamination. Older documents refer to all bands available, whilst modern documents only refer to those most commonly used.

Sterilisation Bands

Listed below are the sterilisation temperature bands provided for decontamination in a healthcare environment, across all guidance documents.

As well as the sterilisation temperature requirements, detailed information regarding which document referes to the particular band is also provided, along with useful measurement information.

Sterilisation temperature bands listed are:
