CE marking is a broken idea
“Similar issues can be found with power line communication (PLC) adapters, plasma tvs etc.”
The example of CE-marked PLC illustrates how broken the whole self-certification system is in the EU. Many (all?) PLC devices break rules on radio interference when used on standard domestic wiring, but all is supposedly well as the devices carry CE markings. This is despite the reality that self-certification that justifies the CE marking involved testing samples using “standards” that were never approved (because they were too lax), or measurements in an environment that did not replicate domestic wiring, or using interference thresholds intended for industrial, non-domestic use. It then seems that manufacturers are effectively allowed to “grandfather” the supposed CE compliance.
As I recall, a ruling in German appeared to suggest all was in order, so no other national authority is willing to do anything about these dodgy practices. In the UK, complaints about illegal PLC interference are dealt with using a crazy ad hoc procedure that involves the BBC (rather than relevant regulator, Ofcom), allowing Ofcom to report it has received no complaints, justifying its refusal to act. Even the IEEE is complicit in setting up standards for this crap without considering the wider issues.
The issue of CE marking is one where there is a clear case for EU reform, but unfortunately its this kind of “trust the manufacturers” crap that is supported by those who claim to be concerned about the EU.
