I don't think it's that bad, the company I work for has its products
tested to make sure they conform to the appropriate regulations,
normally the industrial regs. As I understand it though the rules
require companies to have there products tested or do self certification
and after that if CE marked products are found to fail then they should
be reported for failure so the enforcement bodies can prevent further
sale. I'll ask the next time I'm in the office when the guy is back, if
he reported the products to the appropriate authority.

What, if any, action do the US authorities take to fake FCC or UL
markings on products. I've seen it mentioned that those are all too
common like fake CE markings. IIRC one person on this newsgroup said
recently that they would prefer CE certified equipment to FCC as the FCC
only dealt with emissions, whereas the CE dealt with emissions and
susceptibility to environmental EMI.

Regarding CE being "Can't Enforce", I liked the meaning of NTSC being
"Not The Same Colour", likely obsolete, or almost, these days with the
change over to digital.


That stupid "Not The Same Color" phrase has been obsolete since VIR &
VITS was introduced in the '70s. The problem was mostly caused by the
cross country coaxial and microwave TV network feeds. Different shows
arrived by different routes and had different phase delays. VIR put
phase reference signals in the vertical interval to allow for automatic
correction at every amplifier or switch.
