EXPLORING DIFFERENCES BETWEEN STEAM PENETRATION IN A B&D TEST PACK AND IN A CHANNELLED INSTRUMENTFrancesco TessaroloDepartment of Industrial Engineering University of TrentoINTRODUCTIONSteam sterilization requires that all surfaces to be processed are exposed long enough to steam sterilization conditions (i.e. defined combination of temperature and time in the presence of sufficient humidity).According to standards the steam penetration capacities of a sterilizer should be tested with a steam penetration test [ISO 17665:2024]. TimeTemperatureSteamcompositionINTRODUCTIONIn the early 1960s Bowie and Dick developed the first steam penetration test. This test was further developed and minimum performance requirements are defined in standards [ISO 11140-3, 11140-4, 11140-5].The original "Huckaback Towel Pack" according to Dr.J. H.
