Design and production must keep low the risk from anything that can leach out of the device, the risk from substances accidentally entering or escaping it in its use environment, and the risk from particles, judged by their size and properties, that the device sheds or may shed into the body of a patient or user, taking special care with nanomaterials. The particle requirement does not apply where particles contact intact skin only.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
