The Association for the Advancement of Medical Instrumentation (AAMI) released three standards on the use of chemical indicators in steam sterilization applications.
A chemical indicator is used to demonstrate that desired sterilization conditions were achieved when sterilizing a medical instrument or set of instruments.
Each standard pertains to a specific aspect of the Bowie and Dick-type test, which is designed to indicate rapid and even penetration of steam into a sterilization test pack.
The standards were adopted from their International Organization for Standardization (ISO) counterparts.
ANSI/AAMI/ISO 11140-3:2007 - Sterilization of health care products - Chemical indicators - Part 3: Class 2 indicator systems for use in the Bowie and Dick-type steam penetration test is identical to ISO 11140-3:2007.
ANSI/AAMI/ISO 11140-4:2007 - Sterilization of health care products - Chemical indicators - Part 4: Class 2 indicators as an alternative to the Bowie and Dick-type test for detection of steam penetration is identical to ISO 11140-4:2007.
ANSI/AAMI/ISO 11140-5:2007 - Sterilization of health care products - Chemical indicators - Part 5: Class 2 indicators for Bowie and Dick-type air removal tests is identical to ISO 11140-5:2007.
