            The selected operating cycle of a porous load sterilizer normally have five stages.

  • Air Removal – Sufficient air is removed from the chamber and the load to permit attainment of the sterilization conditions.
  • Steam Admission – Steam is admitted to the chamber until the specified sterilization temperature is attained throughout the chamber and load.
  • Holding Time – The temperature throughout the chamber and load is maintained within the sterilization temperature band for the appropriate holding time.
  • Drying – Steam is removed from the chamber and the chamber pressure is reduced to permit the evaporation of condensate from the load by prolonged evacuation.

5.2.2 Bowie Dick Test:

Follow respective SOP to perform the Bowie Dick Test during the study. Record the observations and results in formats enclosed as Exhibit-E02.

5.2.3 Bowie-Dick Test Papers

  • The Bowie-Dick test uses a Class B chemical indicator contained within a standard test pack.
  • The indicator is distributed over an A4 paper sheet in the form of a geometric pattern.
  • This indicator paper is placed at the centre of a test pack of folded huckaback towels and then subjected to an operating cycle. The indicator tape shows a change of color in response to a combination of time, temperature and moisture.
  • When used in conjunction with a standard test pack, Class B indicators are designed to show a failure either if, at the start of the holding time, the temperature at the centre of the test pack is 2°C or more below the temperature in the active chamber discharge; or if the indicator is exposed to insufficient moisture.
  • Both conditions are usually caused by the presence of air or other non-condensable gases

Acceptance Criteria

  • There should be a uniform colour change throughout the indicator.
  • No change, non-uniform change and/ or air entrapment (bubble) spot on the   Pattern indicates inadequate air removal from the sterilization chamber.
