適用范圍：This part of ISO 11140 specifies the performance for a Class 2 indicator to be used as an alternative to theBowie and Dick-type test for steam sterilizers for wrapped health care goods (instruments, etc., and porousloads).NOTE The Bowie and Dick-type test is used for routine testing of steam sterilizers and validation of steamsterilization processes.An indicator complying with this part of ISO 11140 incorporates a specified material which is used as a testload. This test load may, or may not, be re-usable. This part of ISO 11140 does not specify requirements forthe test load, but specifies the performance of the indicator in combination with the test load with which it isintended to be used. The indicator specified in this part of ISO 11140 is intended to identify poor steampenetration but does not necessarily indicate the cause of this poor steam penetration.This part of ISO 11140 does not include test methods to establish the suitability of these indicator systems foruse in sterilizers in which the air removal stage does not include evacuation below atmospheric pressure.
