This part of ISO 10993 specifies allowable limits for residual ethylene oxide (EO) and ethylene chlorohydrin
(ECH) in individual EO-sterilized medical devices, procedures for the measurement of EO and ECH, and
methods for determining compliance so that devices may be released. Additional background, including
guidance and a flowchart showing how this document is applied, are also included in the informative annexes.
EO-sterilized devices that have no patient contact (e.g., in vitro diagnostic devices) are not covered by this
part of ISO 10993.
