Dear All,

I have submitted an electronic ballast (ballast designed for building-in and
provided with pigtail leads  used for installation at the base of road
lamps) to a reputable German test house for investigation and the following
points were discovered:

1. PCB is not European approved!!! I convinced them (do not know how!) that
a UL Recognized board is OK to use.

2. Leads are UL and must be approved to a European Standard by a European
test house. Tried for half an hour to convince them that the ballast is
designed for international usage and UL Listed or Recognized leads would be
sufficient. They insist that the leads must be European approved. 

Question: Anyone knows of manufacturers of leads which are UL and also
approved by a European test house?

3. Ballast fails a hipot of 1500 Vac. Told them to conduct test at 2121 Vdc
(1.4 x Vrms) because of the filtering but they insisted that luminaire
standards always require a test with an ac applied voltage. Was unable to
convince that most standards allow the use of an ac or a dc voltage equal to
the 1.4 x Vrms.

Question: Anyone knows of a quick way (other than the autobahn) through the
German Appeals Procedure? It took 4 months just to begin the tests!. I do
not wish to wait another year for the Appeal!

4. In the case of faults within the ballast, they require a fuse or other
overcurrent protective device within the ballast and not to rely on the main
16 A breaker on the road lamp installation. I told them that the ballast
installation instructions specify an overcurrent protective device between
the main 16 A breaker and the power supply input. They are still requring a
fuse or fuselink within the ballast.

Question: Anyone with a similar problem?


Thanks to All,

PETER MERGUERIAN

Hi Zohar:

The Scope of EN41003 reads:

"This standard applies to equipment designed and intended to be
connected to
a TELECOMMUNICATIONS NETWORK termination. It does not apply to equipment
covered by EN60950."

Therefore, equipment intended to connect to the network that is not ITE
(for
example Test and Measuring, Process Control, Laboratory equipment, and
whatever others) should use EN41003 for the requirements to be applied
to
the network connection.

As internet applications proliferate, more and more product categories
other
than ITE will likely need to use these requirements. Although EN41003
references EN60950 in a number of areas, not all of the EN60950 clause 6
requirements are referenced, and EN41003 adds a few other requirements.
Also, EN41003 has an interesting Annex C which describes why
telecommunication voltages which exceed "safe to touch limits set within
general safety standards" are actually "electrically safe".

I hope that helps some.

Hello to all,

Any one familiar with EN 41003:1999 standard, if yes, where is it
applicable?
Does EN 60950/IEC 60950 covers EN 41003 requirements?
