DANSK DSF/ISO/DIS 22441 PDF

1.1 Inclusions 1.1.1 This document provides requirements for the development, validation and routine monitoring and control of a low temperature sterilization process for medical devices using vaporized hydrogen peroxide (VH2O2) as the sterilizing agent. 1.1.2 This document is intended to be applied by process developers, manufacturers of sterilization equipment, manufacturers of medical devices to be sterilized, organizations performing process validation of VH2O2 sterilization, and organizations responsible for sterilizing medical devices. NOTE – VH2O2 sterilizers can be used in both health care and industrial facilities, and this document acknowledges the similarities and differences between the two applications. 1.2 Exclusions 1.2.1 Processes that use other sterilizing agents, or hydrogen peroxide in combination with other chemicals as the sterilizing agent are not addressed in this document. NOTE – See ISO 14937 for guidance on validation of such processes. 1.2.2 This document does not specify requirements for development, validation and routine control of a process for inactivating the causative agents of spongiform encephalopathies such as scrapie, bovine spongiform encephalopathy and Creutzfeldt-Jakob disease. Specific recommendations have been produced in particular countries for the processing of materials potentially contaminated with these agents. NOTE – Some VH2O2 sterilizers have processes that demonstrate some level of inactivation of the causative agents of spongiform encephalopathies such as scrapie, bovine spongiform encephalopathy and Creutzfeldt- Jakob Disease. However this inactivation is process, cycle, and test protocol specific, therefore this inactivation is outside the scope of this document, and no specific test methods are provided.
