Qualification of pure steam

Qualification of pure steam used in pharmaceutical applications (in steam sterilizers for sterilization of parts, instruments, and assemblies, porous loads, in SIP systems) is an essential part of the quality assurance system of delivered products. 

You may order clean steam testing or perform this procedure yourself, but you will need a test kit to do this. 

Qualification of pure steam is documented evidence that: 

  • the level of non-condensable gases contained in the steam will not prevent the attainment of sterilization conditions in any part of the sterilizer load; 

  • the excess moisture carried in aerosol will not cause damp loads;  

  • the amount of moisture in suspension with steam from the service supply is sufficient to prevent the saturated steam from becoming superheated during expansion into the sterilizer chamber; 

  • the quality of pure steam condensate (bacterial endotoxins, total organic carbon, and conductivity) is within specifications.
