Internal combustion engines and electrical equipment of categories M 2 and 2 need EU-type examination combined with either internal production control plus supervised product testing (Module C1) or product quality assurance (Module E). Other category M 2 and 2 equipment follows internal production control (Module A), and the manufacturer must send the technical documentation to a notified body, which acknowledges receipt as soon as possible and keeps it.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
