Main revisions in ISO 10993-17: 2023 for the biological evaluation of medical devices.

UL Japan
In September 2023, ISO 10993-17 was revised for the first time in nearly 20 years. The ISO 10993 series of standards primarily deals with the biological evaluation of medical devices, and ISO 10993-17 specifies the requirements for the assessment of toxicological risks of substances identified through chemical characterization (ISO 10993-18). ISO 10993-17:2023 introduces new terms and concepts such as Toxicological Screening Limit (TSL), Estimated Exposure Dose (maximum; EEDmax), and release kinetics. It also provides a flowchart illustrating how the toxicological risk assessment framework can be integrated into the risk management process for medical devices and toxicological risk assessment reports.
