Description / Abstract:

This Standard specifies requirements for dry heat sterilizers of the hot air type intended for use in hospitals, hospital laboratories, office-based health care facilities and similar situations for the sterilization of instruments, metalware, glassware and oils.

This Standard does not apply to machines that sterilize—

(a) liquids, oils and greases that have a boiling point less than the selected sterilizing temperature; or

(b) fluids in non-vented bottles.

NOTES:

1 The Standard applies to sterilizers that utilize circulated electrically heated air to maintain uniform sterilizing temperatures throughout the chamber.

2 The sterilizers maintain a sterilizing temperature of not less than 160°C and an automatically controlled and recorded sterilizing cycle, to achieve the sterilizing function.

3 The operating temperature and other details need to be discussed at the time of enquiry or order. Attention is drawn to the need to verify that the material to be sterilized can satisfactorily withstand the sterilizing temperature, which is not less than 160°C. For special purposes, a set temperature of 200°C may be required.

4 Dry heat sterilization is used for anhydrous items and items sealed within impermeable containers that cannot be sterilized by steam under pressure but can withstand a temperature of 160°C for a minimum holding time of 120 min plus the penetration time.

5 While sterilizing oils or greases, flammable vapours may be produced, which could be hazardous.

6 Where oils to be sterilized are intended for use in eye drops or injections, additional equipment (e.g., a simulated load probe and recorder) is required to reduce hazards to public health.
