Ethylene Oxide (EO) Chemical Process Indicators (CPIs) are manufactured to meet performance specifications described in ISO 11140-1 “Sterilization of health care products – Chemical indicators – Part 1: General requirements,” for Class 1 Process Indicators. The purple-to-green colour transition is sensitive to time, temperature, humidity and presence of EO (see chart). EO CPIs are not intended for use as sterility indicators, but rather as throughput process indicators used to monitor exposure to EO sterilization processes.
