Use of harmonised standards
This article requires the use of harmonised standards and subsequently, a discussion of their applicability in parts or in whole.
Using such standards is assumed compliant to the MDR 2017/745. Please be adviced that EN standards are EU harmonised standards and have to be primarily used. These standards sometimes are adopted or accepted as consensus standards in other jursidictions, e.g. by the U.S. FDA.
The best practice is to list all applicable standards (in an applicable standards list, short ASL) and discuss their partial or entire applicability. For product development with a multi-jurisdiction focus, you might even find it helpful to mark whether the used standard is accepted by either adoption or consensus in other jurisdiction and extend the list with jurisdiction-specific harmonised standards.
