What is BS EN ISO 10993-17:2014?

BS EN ISO 10993-17:2014 is a technical standard created by the British Standards Institution (BSI) and it is part of the ISO 10993 series that deals with the biological evaluation of medical devices. This particular standard focuses on the assessment of biocompatibility through in vitro cytotoxicity testing.

The Importance of Biocompatibility Testing

When medical devices come into contact with the human body, it is crucial to ensure that they do not cause harm or adverse reactions. This is where biocompatibility testing plays a vital role. Biocompatibility refers to the ability of a medical device to perform its intended function without causing any harmful effects on the patient.

BS EN ISO 10993-17:2014 specifically addresses cytotoxicity testing, which evaluates the potential toxic effects of a medical device on living cells. Cytotoxicity tests are performed using cultured mammalian cells, where the device or its extracts are exposed to the cells to evaluate their response. This helps determine if the device releases any substances that may be hazardous to human health.

Understanding BS EN ISO 10993-17:2014

BS EN ISO 10993-17 outlines the general principles for conducting cytotoxicity tests on medical devices. It provides guidance on sample preparation, selection of appropriate test methods, and interpretation of test results. The standard also emphasizes the importance of considering various factors such as the nature of the medical device, its duration of contact with the body, and the intended population when designing and conducting cytotoxicity tests.

The purpose of these tests is to identify potential risks associated with the device materials and assess whether they are within acceptable limits. By following the guidelines outlined in BS EN ISO 10993-17, manufacturers can ensure that their medical devices are safe for use and meet regulatory requirements.


BS EN ISO 10993-17:2014 is an essential standard that plays a critical role in ensuring the biocompatibility of medical devices. By adhering to the guidelines outlined in this standard, manufacturers can assess the potential cytotoxic effects of their devices and ensure patient safety. Cytotoxicity testing forms a crucial part of the overall evaluation process, helping identify any risks associated with the device materials. Ultimately, BS EN ISO 10993-17 assists in the development and production of medical devices that are both effective and safe for patients.
