This international standard addresses good clinical practices for the design, conduct, recording and reporting of clinical investigations carried out in human subjects to assess the safety and performance of medical devices for regulatory purposes. However, it does not apply to in vitro diagnostic medical devices.

This standard was developed by ISO technical committee ISO/TC 194. ISO 14155 was published in its second edition in February 2011.


the first edition of ISO 14155-1 was published on 15 February 2003. The latest revision of the standard was released in February 2011 and hence, the current version of the standard is ISO 14155:2011.
