Peter,

the initial and most important point would be to define the appropriate
European standard. I do not know exact what luminaries you are using for
your ballast for, but EN61046 “DC or AC supplied electronic step-down
converter for filament lamps” might be appropriate.

To your questions:
PCB board- the standard refers to EN60249 Basis material for PCB boards. My
understanding is, that FR4 material fulfils the requirements. It does not
require European or UL approval. The standard EN61046  requires a humidity
test (similar to IEC60950).

Leads- The standard does contain a clause to require European or UL approved
leads. Nevertheless, the voltage rating and wire size has to be appropriate.
Of course, having the right approval will make things easier.  You might
have to describe the insulation, thickness, material of the leads in the
safety critical component list.

Dielectric testing- the standard (table 2) specifies 1500 V a.c. dielectric
testing for primary to secondary. It insists on AC testing. (clause 13.1) .
Please take in consideration, that a IEC60950 will require 3000 V a.c. or
4200 V d.c. , which is much harder.

Fuse- the standard defines the abnormal testing in clause 16. It does not
require a built in fuse, as long as the abnormal testing will be passed.

The European mark for ballast might be the ENEC mark, which is strictly
based on the standard. The GS-mark is also appropriate, but is based on the
German law of safety AND the standard. The GS –mark also addresses points
like handling, manual, appropriate installation and is therefore with
additional  requirements. Ten years ago it was very important to select the
right mark, today ENEC or the GS mark from any European test house should
not be any disadvantage for marketing in Europe.

With best regards
Horst

Betreff: Re: Stuck in Germany!

Peter,

And which standard is it that has all these requirements specified!

I've had some unfortunate experiences some time back with German test houses
demanding that all sorts of unexpected compliances be met.   I very firmly
and politely asked them to show me just where and in which standard these
requirements are stated.   After some back and forth verbal negotiations,
they came back to say that it is not in the standard but that is still a
requirement, etc.,  "...and it is the right thing to do...!"    My response
was that these mandatory requirements should be stated in writing up front
rather than surprising their clients later on in the investigation.   I
persisted and finally they relented.

I am not saying that in this case these requirements are not justified (I
know nothing of ballast lamps!)   But you certainly should be more assertive
in finding out where these requirements are coming from.

My other suggestion (and too late for you) is not to deal with German test
houses if at all possible.   I believe there is a harmonized standard for
luminaires (or is that only for household use?) that might enable you to go
through other test houses in Europe.

Subject: Stuck in Germany!


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?
