K.21 Power Induction Tests

[emc-p...@ieee.org]

Hello All,
 
Can anyone in the group recommend a lab that is set up to perform the
600 V, 16 2/3 Hz power induction tests called out in ITU Recommendation
K.21?
 
Thanks in advance.

Re: New lists of Harmonized Stds for Machinery, Lifts (elevators) and PPE (personal protective equipment )

[emc-p...@ieee.org]

As to deciding which version of EN 60204-1 to use:
a small added complication is that it is on the harmonized lists for both MD
and LVD. 
(At the moment, both lists are in agreement, with each other if not with
Cenelec!)

There are other examples (LVD & MD), such as EN 60335-1.

And EN 61131-2 (PLC's) is both an EMC and a LVD standard.

Subject: Ethernet bulkhead


HI All,

I've been looking for a bulkhead ethernet connector that will terminate a
shielded cable. I've found a whole bunch of plain old connectors, but I'm
trying to avoid making an adaptor.

Note, this is for passing the signal out of a shield room, it's not intended
for deployment.

Can anyone point me to something I could use please?

Thanks,

Derek Walton 

 
Derek:
 
I got some samples of a heat-shrink tubing that had metallization on its ID
and OD. The idea is that it can form a contiguous shield over a cable shield
and onto a metal backshell. The samples I got were various diameters of
tubing, but I understand that this idea is also available in pre-formed shapes
that will fit things like a DB25 connector or an Ethernet connector.
 
One vendor is   http://www.methode.com 
 
BTW, a "packing gland" is another trick I use for cable penetrations on my
test chamber. You mount a short straight section of brass water-pipe into a
hole in the shield wall (or penetration port cover). You put a brass pipe cap
(drilled to allow passage of the coax [or other cable]). You strip off a
length of the insulation covering the cable shield (a bit longer than the
brass pipe length). You thread the coax through the inner pipe cap, and screw
that cap to the pipe. Outside, you slide the coax through the other pipe cap,
but before you put it on the pipe, stuff as much bronze wool into the pipe as
possible (keeping the cable somewhat centered). When you screw on the outer
pipe cap, it will compress the bronze wool and ensure a nice ground for the
shield.
 
This has the advantage of not disturbing the cable structure, and it
eliminates the loss caused by two additional cable connectors and a
feedthrough assembly. I use this on my permanent 1 GHz to 18 GHz test coax.
 
The really "quick & cheap" way is just to use a crinkled wad of aluminum foil
as a collar around a cable as it goes through a hole in the shield. Not
pretty, only temporary, but works great if you do it right. I go through a lot
of aluminum foil!

Re: New lists of Harmonized Stds for Machinery, Lifts (elevators) and PPE (personal protective equipment )

[emc-p...@ieee.org]

Scott,
 
A test standard or a product family/product standard or a generic standard is
ratified/adopted by CEN/CENELEC/ETSI and therefore "applicable" as a normal
standard (product liabillity!!!) but NOT under the "CE regime" until the
publication in the OJEU! That is a time problem because e. g. the "LVD
standards list" will be updated once a year (last publication was on
2006-08-30 http://eur-lex.europa.eu/Lex
riServ/LexUriServ.do?uri=OJ:C:2006:208:0001:0089:EN:PDF  in the OJEU WITHOUT
the new versions of EN 60204-1:2006 or EN 60950-1:2006 for example).
 
We had some difficult discussions in the past 3 weeks with different
statements of the German Ministry.

That is one of our big problems in Europe: 
  
CENELEC/CEN/ETSI are publishing new standards e.g. EN 60204-1:2006-06 but the
commission don´t publish these reference "just in time"! Therefore the new
standards haven´t a "presumption of conformity" in the meaning of the "new
approach"! We have a long list of new standards under the Low Voltage
Directive, EMC, R&TTE Directive, PPE, Toy, Medical and so on with the same
problem! 
  
We inform our database users about this "special situation" of european
harmonized standards.

[emc-p...@ieee.org]

EN 692 has been the subject of a long running argument about the use 
of two hand controls. I've not looked at the new version, but I think 
this is likely to be the main area of concern about old standard.

Let me know if you really want to know more and I'll ask my press 
specialist what he sees as the main differences.

Nick.

RE: EN 60950-1 RS485 and TNV-1

[emc-p...@ieee.org]

Piotr -

There is a CENELEC Report/ETSI Guide, EG 201 212 V1.2.1.  This document
provides guidelines for determining whether a circuit is SELV or TNV and
is still available (labeled as 'historical') from ETSI's web site.

FWIW, as late as 2005, a BT Suppliers Information Note, SIN349 v2.0,
references that document.

Re: EN 60950-1 RS485 and TNV-1

[emc-p...@ieee.org]

Joe,
 
If that exemption were not there, the connection between mouse and PC I would
understand as TELECOMMUNICATION NETWORK.
 
Lighting cause ground differences so I do not suppose underground cables being
free of lighting transients.
 
The question left:
If my connection is the TELECOMMUNICATION NETWORK then my circuit is TNV-1 but
does it work in opposite direction ?
If I classify my circuit as TNV-1 do I need to read Cl. 6 ?

Hi Piotr:

This topic was discussed recently on this board.  I believe that the exemption
for "SELV circuits connecting units of information technology equipment" was
inserted in 1.2.13.8 to cover the type of situation that you describe.  

Unfortunately, it becomes a matter of judgement as to whether such a cable
might be subject to lightning transients.  If the cable run is very short and
is run underground, you could probably argue that it is not subject to
lightning transients and it can be classified as SELV.  However, if the cable
run may be long and/or it may be strung above ground, it is probably wise to
classify it as TNV-1.  The final decision about how to classify the cable will
rest with you and your safety test agency.
