DIN EN ISO 11138-2 specifies requirements for test organisms, suspensions, inoculated carriers, biological indicators and test methods intended for use in assessing the performance of sterilizers and sterilization processes employing ethylene oxide gas as the sterilizing agent, either as pure ethylene oxide gas or mixtures of this gas with diluent gases, at sterilizing temperatures within the range of 29 °C to 65 °C. The International Standard has been prepared by ISO/TC 198 "Sterilization of health care products" in collaboration with CEN/TC 102 "Sterilizers for medical purposes" (secretariat: DIN). The responsible German committee is Working Committee NA 063-04-08 AA "Indikatoren" ("Indicators") at DIN Standards Committee Medicine.
