Medical. The specification is ISO 13485 (Medical Device Quality Management) in the standards register (International Organization for Standardization (ISO), version ISO 13485:2016).
This register says what each scheme asks for. It never says that a product, design, company or site meets a scheme: that is the determination of the body that runs the scheme.
Medical: conformance attaches to an organisation.
The level scale, validity, test families, applicability by market, the regulations that invoke the scheme and the accredited bodies are for registered members. Registration is free and takes a minute. You come back to this page afterwards.
