ISO 10993-7:2008规定了各种EO灭菌医疗器械中残留环氧乙烷（EO）和氯乙醇（ECH）的允许限值，EO和ECH的测量程序以及确定依从性的方法，以便器件释放。额外的背景，包括指南以及如何应用标准的流程图也包括在资料性附件中。 没有患者接触的EO灭菌装置（例如，体外诊断装置）未被ISO 10993-7:2008涵盖

ISO 10993-7:2008 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 the standard is applied are also included in informative annexes. EO-sterilized devices that have no patient contact (e.g., in vitro diagnostic devices) are not covered by ISO 10993-7:2008.
