Get to know ISO 10993 - part 5

ISO 10993 is a series of standards created for evaluating the biocompatibility of medical devices, which can range from dental implants to surgical masks, to manage biological risk. In reference to these standards, “biocompatibility” is defined as the "ability of a medical device or material to perform with an appropriate host response in a specific application."

Part five of these standards focuses on tests for in-vitro cytotoxicity, which is the quality of being toxic to cells. These tests are conducted with human or animal cell cultures and are required for all types of medical devices and assist in the selection of the materials used to make them.

Where it applies

ISO 10993 standards apply to select pharmaceutical products.
