Description / Abstract:
This part of ISO 11140 specifies the performance for a Class 2
indicator to be used as an alternative to the Bowie and Dick-type
test for steam sterilizers for wrapped health care goods
(instruments, etc., and porous loads).
NOTE The Bowie and Dick-type test is used for routine testing of
steam sterilizers and validation of steam sterilization
processes.
An indicator complying with this part of ISO 11140 incorporates
a specified material which is used as a test load. This test load
may, or may not, be re-usable. This part of ISO 11140 does not
specify requirements for the test load, but specifies the
performance of the indicator in combination with the test load with
which it is intended to be used. The indicator specified in this
part of ISO 11140 is intended to identify poor steam penetration
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 for use in
sterilizers in which the air removal stage does not include
evacuation below atmospheric pressure.
