RE: RTTE and E-Mark applicable?

2002-08-22 Thread w w

Thank you all for helping. I believe I know the right
approach now for devices that can straddle the fence.

It will be interesting if there is more clarification
about this before Oct 2002 like Mr. Woodgate
mentioned.

Neil, my scenario for the laptop needing E-Mark would
then only apply to the cigarrette lighter adapter
that powers the laptop, simalr to your hands-free kit
scenario for cellphones.

Thank you all again.

 I believe that your interpretation of the marking

 Devices that are intended for use in vehicles need

 Devices intended for both
 environments will need both markings.
 I am concerned, however, with your interpretation of
 the type of devices
 that may need to be e-marked.  A laptop would only
 need to be e-marked if it
 was intended to be installed in a vehicle.  A
 regular laptop that is simply
 used in a vehicle is not subject to the Automotive
 EMC Directive.  If this
 were not the case, then potentially all laptops
 could be used in vehicles
 and all would require to be e-marked!
 Similarly for radio devices. A mobile radio
 (receiver or transmitter) that
 is intended for installation in a vehicle does need
 to be e-marked. However,
 a portable radio that can be carried in and out of a
 vehicle (e.g.
 cellphone) does not require to be e-marked, but any
 adaptor that is intended
 to be permanently installed in the vehicle for use
 with such a portable
 device would need to be e-marked. So, your cellphone
 does not need to be
 e-marked, but the installed hands-free adaptor does
 need to be e-marked.
 I hope that this clarifies the position for you.

  would need to show compliance to both EU

  placing both marks on the device(E  CE Mark).
  
  One does not supercede the other.
  
  Thank you in advance.

Does anyone know what JAA testing is?

I heard something it may be affiliated with RTCA

Any feedback is most appreciated.

IEC 61000-4-5 Surge Lower Levels

2002-06-11 Thread w w

Thank you all for the feedback on lower levels for
ESD. What an education! Without question, we certainly
need to consider lower-levels to minimize ESD
failures/issues in the field.

How about Surge? Is it overkill performing lower
levels? Should this only be considered for devices
with gas tube arrestors etc..?

Then the last question, is lower levels only a concern
for the -2  -5? Why not IEC 61000-4-3, -4, -6, -8
etc.. (I'm guessing because these are considered
continuous phenomenons and only non-continuous seems
to be of concern)

Thx

IEC 61000-4-2 ESD 61000-4-5 Surge lower levels

2002-06-07 Thread w w

Hello all,

I'm confused. When preparing an EMC test plan for CE
requirements I've been told to narrow in on Generic or
Product Standards (which ever is more applicable) to
help demonstrate compliance. For example, if testing
to EN 55024 ITE immunity, the standard calls for
various IEC Basic Standards to be carried out. The
severity levels to be perfromed on the EUT is given in
the EN 55024 tables.

I've always been told that:

- The level called out in the Generic/Product standard
takes precedent over the the informative- recommended
sevrity levels (for a given environment,level 1-4
etc)in the IEC Basic's

- The Basic's are only to be used for set-up and how
to perfrom the test. 

Here's the question: In the ESD and Surge standard
there is mention in the test methodology that lower
levels shall be applied (I don't see this in the EFT,
Rad Susc. or Cond RF standards). I have heard comments
that only the one set of levels called out in the
Generic/Product standard is all that needs to be
performed. Then I've also been told from other camps
that lower levels MUST be carried out.

If the EN 55024 calls for 1,2 kV for surge on the AC,
does this mean we have to repeat the test @ .5, 1kV
too? For ESD, 8 air, 4 cont should really be 8,6,4,2
air and 4,2,1 cont??

Any guidance would be appreciated.
