BS EN ISO 10993-7:2026

This standard BS EN ISO 10993-7:2026 Biological evaluation of medical devices is classified in these ICS categories:

• 11.100.20 Biological evaluation of medical devices

This document specifies allowable limits (AL) for residual ethylene oxide (EO) and ethylene chlorohydrin (ECH) in EO-sterilized medical devices, procedures for the measurement of EO and ECH, and methods for determining conformity so that devices can be released. Additional background, including guidance and a flowchart showing how this document is applied, are also included in Annexes A, B, C, D, E, F, G, H, I, J and K. EO-sterilized devices or components that have neither direct nor indirect body or user contact (e.g. in vitro diagnostic devices) are out of scope of this document. This document does not apply to devices that have been demonstrated to not absorb or retain EO or its degradation product ECH, such as medical devices made exclusively of metal alloys and glass, see Clause C.5[228]. NOTE            This document does not specify limits for ethylene glycol (EG). No device limits are specified for EG because the risk assessment in Annex F indicates that calculated allowable levels are higher than those likely to occur in a medical device.

BS EN ISO 10993-7:2026 - Biological Evaluation of Medical Devices: Ethylene Oxide Sterilization Residuals

Introducing the BS EN ISO 10993-7:2026, a comprehensive standard that plays a crucial role in the biological evaluation of medical devices, specifically focusing on ethylene oxide sterilization residuals. This standard is an essential resource for manufacturers, quality assurance professionals, and regulatory bodies involved in the medical device industry.

Overview

The BS EN ISO 10993-7:2026 standard provides detailed guidelines and requirements for assessing the biological safety of medical devices that have undergone sterilization using ethylene oxide. Ethylene oxide is a widely used sterilizing agent due to its effectiveness in eliminating microorganisms. However, it is imperative to ensure that any residuals left on the devices post-sterilization are within safe limits to prevent adverse biological reactions when the devices are used in medical settings.
