ISO 13485 is designed to be used by organizations involved in the design, production, installation and servicing of medical devices and related services. It can also be used by internal and external parties, such as certification bodies, to help them with their auditing processes.
Like other ISO management system standards, certification to ISO 13485 is not a requirement of the standard, and organizations can reap many benefits from implementing the standard without undergoing the certification process. However, third-party certification can demonstrate to regulators that you have met the requirements of the standard. ISO does not perform certification.
