scope:

ISO 13408-2:2018 specifies requirements for sterilizing filtration as part of aseptic processing of health care products conducted in accordance with ISO 13408‑1. It also offers guidance to filter users concerning general requirements for set-up, validation and routine operation of a sterilizing filtration process. ISO 13408-2:2018 is not applicable to removal of viruses. Sterilizing filtration is not applicable to fluids that intentionally contain particles larger than the pore size of the filter (e.g. bacterial whole-cell vaccines). ISO 13408-2:2018 is not applicable to high efficiency particulate air (HEPA) filters. ISO 13408-2:2018 does not specify requirements for the development, validation and routine control of a process for removing 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.
