Patrick:
Perhaps the conflict of dates is in the source of the document. The IEC
may say one date and the EU may adopt quite another. As an example: an
EU parallel vote document is usually pretty much in sync with the IEC.
IEC 60950 on the other hand was about 1 and a half years behind the IEC
at one time. It is a lot better today. We must not confuse the IEC
dates with the EU implementation dates.
Having said that the 50 W implementation date is 1999 for the IEC and
would also have been for the EU except for subsequent EU amendments.
The EU extended the dow until 2001 because of the extreme controversy
surrounding the standard from many sources. The same is true for the
flicker standard.
My view is the 50 Watt implementation date is 1999 for home products and
because of the 2001 date for most other products, the 50 Watts means
nothing until 2001. The EU dates always govern the regulatory
requirements.

I was wondering about the 75W-50W change date.
In IEC1000-3-2, paragraph 7.4, it says "This lower limit of 75W
will be reduced
to 50W, four years after implementation date of this standard."
Is the implementation date:
Four years after the date on the cover (1995), or
Four years after the DOW of the standard (now Jan 1 2001)?
If the former is true, does this mean the standard would come
into effect on
the DOW with a 50W lower limit?
