EMC of Vehicle Sub Assemblies - "e" Mark
Some of the automotive "extras", such as car stereos, alarm systems, power sunroofs, mobile phone adapters, navigational systems and high-mounted stop lamps, are also under scrutiny for EMC (electromagnetic compatibility).
Compliance with the 72/245/EEC is indicated by the "e" mark, which is fitted to the sub-assemblies. It allows component manufacturers to demonstrate to existing and potential customers that their product meets the applicable automotive EMC requirements.
It can also simplify the certification process for the manufacturer significantly, i.e. if all relevant electronic and electric systems have been individually approved, no further testing is required on the vehicle. Additionally, components which are covered by the Automotive EMC Directive and comply with the EMC Directive 2004/108/EC may be marked with the CE Marking.
"Components", in the sense of the directive, are electrical and electronic sub-assemblies intended to be part of a vehicle, together with any associated connections and wiring, which perform specialized functions. Any components that are involved in the direct control of vehicles, like alternators, ignition coils and starters, will normally receive type-approval in conjunction with a vehicle, and do therefore not require separate approval.
