Re: IP testing again, but in China

2004-11-19 Thread owner-emc-p...@listserv.ieee.org 
Dear John,
 
SIEMIC InfoTech (China) Ltd can do IP testing in Beijing, China (
www.siemic.com.cn).
 
Pls bear in mind, most of IP products are NOT able to get China MII approvals
at this time, i.e. China MII (ministry of Information Industry) has not fully
acceptance of IP products for two reasons (Security and Toll), although
testing can be performed. 
 
You need to make sure your products can be MII approved before proceed to any
test lab for testing to avoid unnecessary cost of testing, unless you are not
interested to get Chinese approvals.
 
Contact us for a free evaulation if your IP product is able to get MII
approval before spending on testing.
 
With true China approval specialists familiar with China markets and
regulations, located in the heart of political center and "Silicon Valley" of
China (Beijing Zhong Guan Cun), SIEMIC InfoTech Ltd is the second-to-none
one-stop shop services provider for China approvals.

RE: Heart pacemakers - Vulnerability to EM

2004-11-19 Thread owner-emc-p...@listserv.ieee.org 
I have just a bit of personal experience in testing implantable pacemakers and
volumetric infusion pumps. I had been doing RF immunity studies for a
manufacturer, circa 1990, using an FDA standard (MDS-401-xxx?) for medical
electronic devices.

  
I exposed devices to fields as strong as I could create (10 kHz through 18
GHz, always at least 200 V/M, sometimes as high as 600 V/M), using both 1 kHz,
50% duty cycle and a 200 Hz, 10% duty cycle, gated at a 1 Hz rate. The devices
were tested first in open air, and then immersed in a rectangular tank of
saline solution (a crude attempt to simulate body tissue). I also exposed them
to 20 Oersted DC & 60 Hz magnetic fields (the infusion pumps had a magnetic
communications link for programming and monitoring).

  
The nice part is that, after some design changes, I was unable to elicit any
improper responses from the devices. Since these devices were so nicely
immune, I imagine that a person would feel the effects of tissue heating well
before the electronics are jeopardized.

  
I hope they still make them as good now.

Subject: RE: Heart pacemakers - Vulnerability to EM 


I am no expert in this subject, and some of what I am about to say is
hearsay, but here it is for what it's worth.

 
Safety levels are generally based not on field strength, but on power
density. However, these levels are set for the power absorption of the body
(in W/kg) based on the heating effect. For comparison purposes consider the
acceptance levels applied to SAR testing. On this basis, I suspect that Dave's
amateur rig probably doesn't meet SAR acceptance levels, and should probably
have an exclusion zone around the antenna!

 
The original message was concerned with the effect on a pacemaker
rather than directly on the body itself. Clearly, if you disrupt a pacemaker
then it is the pacemaker that has an effect on the body.

I believe that the susceptibility depends greatly on whether they are
external pacemakers or implanted pacemakers. The implanted devices are much
less susceptible as they are completely surrounded by soft body tissue, which
is largely water in any case. External devices are much more susceptible, due
largely to the relatively long electrode wire. being long, this is generally
susceptible at fairly low frequencies, and I have heard that they can be
affected by the magnetic loops used in store doorways for security
(merchandise protection) purposes. I have no knowledge of their susceptibility
to E fields.

RE: Heart pacemakers - Vulnerability to EM

2004-11-19 Thread owner-emc-p...@listserv.ieee.org 
The standards EN 50061 /EN 45502-2-1 are dealing with the immunity of pace
makers. 

Immunity is tested in a torso simulator and a specific antenna to transmit
close to water at the right frequency.

The problem is not the pacemaker itself, it is the fact that the sensors
provide a good antenna.

Beside this modern pace makers additionally have a mode of operation they go
into if they got interference with a certain level above the normal
interference they have. 

They don’t sense anymore and got to a fixed  rhythm.

 

Even with that relatively high level of immunity there are devices people with
pace makers have to stay away like high power transformers and all devices
creating a high magnetic field (MRT).  Electric shavers, hairdryers and tolls
like electric drills also have a potential to disturb the function if used
close to the pace maker.

RE: NEBS Compliance of Single ATCA card

2004-11-19 Thread owner-emc-p...@listserv.ieee.org 
Duncan,

You are on the right track by doing all the board-level tests up front. Your
customer will have to integrate the blade into their ATCA application and get
the entire system NEBS certified and approved by the end-customer (Verizon,
SBC, AT&T, etc.). I would also recommend that you don't overlook testing for
the EN 300 386 requirements that will be required for deployment into European
COs.

Here is a list of tests that I would recommend you perform to help ensure your
card won't be the weak link in any system ATCA application:

- Applicable surge testing which is dependant on the type of interface, i.e.,
intra-building or outside plant. (See appendix B in GR-1089 to determine your
type of equipment.)
- ESD according to GR-1089 (inside an ATCA chassis) and GR-78 (bare board)
- Radiated emissions inside a chassis - don't forget the extended GR-1089
limits
- Conducted emissions on all cables. DC power conducted emissions may be of
interest as well.
- EFT on all cables.
- Conducted immunity on all cables
- Radiated immunity with the board installed in an ATCA chassis
- Short circuit tests!
- Any applicable safety testing (dielectric withstand, thermals)
- Drop testing - bare board
- Thermal operation - inside an ATCA chassis with the neighbouring boards
loaded to the maximum the ATCA allows (300W?).

You may want to also do the following if you have any special components or
concerns:
- Airborne contaminants - inside an ATCA chassis
- Fire spread - inside an ATCA chassis
- DC power transients from AT&T and SBC

The best thing is to read through all of the requirements. The above lists are
>from the top of my head and are probably not all-inclusive. Your specific card
may have features that would necessitate other testing (AC power fault?,
etc.). A Verizon certified test lab will be a big help in deciding on the
applicable tests. You can get the list from:
http://www.verizonnebs.com/tcppage.html.

Subject: NEBS Compliance of Single ATCA card


Group,

One division of our company is looking to design an ATCA card that is
designed to be installed in telco applications, although not directly
connected to a telco network. The card is to be sold as a single card
for systems integrators and therefore requires a chassis or frame to be
able to work. The card is intended for use in ATCA applications and
because of its close proximity to telco applications it is highly likely
that our customers will expect some level of NEBS compliance.

Has anyone in the group had experience of designing a NEBS compliant
ATCA card, and If so do you have any advice or design pointers.

Also as far as I understand, NEBS is a systems level standard so our
single ATCA card cannot comply with NEBS in its own right. Is this
correct?

>From a quick scan of the internet, It appears that most card
manufacturers claim to meet NEBS on single cards, one can only assume
that they have conducted tests relevant to the card i.e. they test to
ensure that the card would not fail NEBS when installed. Either that or
they have tested the card in a NEBS compliant chassis.

Our plan is to specify and design the card to meet the relevant NEBS
requirements and to do basic tests. We would then work with any systems
integrator to provide support for the card for the NEBS testing of their
complete system (in which they have fitted our card). The claim would be
that the ATCA card was 'designed to comply' as we would not have tested
the final system.

Are there any ATCA card manufacturers or systems integrators who may be
able to comment on what they would design for or look for when
purchasing such a card? Any comments or guidance would be grately
appreciated.

Duncan.

Hi Pat,
 
May be it helps reading through the literature on our web (
www.euro-emc-service.de ) with hints to our inventions like GTEM (end of 80s),
EUROTEM (End of 90s) etc, plus background (R&D-web-section) info. 
A size limited TEM device can not do everything but may sometimes prove
useful. Detailed info also in IEC 61000-20. TEM Devices for radiated emission
and immunity.The basic idea is to consider a free space (TEM-basically only
mode) wave inside and for emissions use the concept of t o t a l radiated
power to correlate to OATS.This requires EUT mechanical rotations in a GTEM
(Dr. Perry F. Wilson Algorithm- now working for NIST Bolder Co--He also
published an article I think in IEEE EMC Transaction How to correlate below 30
MHz several years ago (mid 90s?) ). At the Apex you receive (based on simple
e.g. 3, x-y-z orientation of EUT)  voltages vs. frequency to feed into the
software correlation algorithm.  
To be more specific we need to hear details of the product (EUT), in
particular size! Cables do also matter! One TEM cell competitor is e.g.
compact chambers now. What TEM type of cell are you considering? Regulatory
compliance/acceptance under EN 55022/ CISPR 22 issues (accreditation?) may
also be an important issue. IEC 61000-20 is "just" a new basic
standard.normative references? The GTEM is listed in the new ANSI/IEEE
C 63.4.

Subject: Using TEM cells for radiated emissions at 30MHz



Hi: 

I was given some literature by management recently advertising the use of a
TEM cell for radiated emissions: 
http://www.wavecontrol.com/index2004.php?idioma=2 
Our people have the impression that a TEM cell small enough to fit on a
table-top could eliminate the need to go to the local OATS.  I don't think
it's that simple, but I need more solid information. 

The products I test are component power supplies, using CISPR 22 Class A &
Class B limits.  Most of our emissions are in the range of 30-100MHz. 

1) I've heard TEM cells need correlation to an OATS.  Is this a one-time
correlation (like a calibration), or is it tied to the model being tested? 

2) The dimensions of the TEM cell appear small compared to a wavelength at
30MHz.  Does the issue of near-field and far-field zones still apply in a TEM
cell?  If so, how do you correlate the two? 

3) The product appears to have pyramid absorbers inside (no reverberation). 
Does this mean the EUT needs to be repositioned several times during the test? 

4) How do the TEM cell correlation factors and noise floor of the spectrum
analyzer interact?  Do I need a certain maximum noise floor in order to make
measurements? 

I guess I'm looking for a TEM cell tutorial, or maybe a book or paper titled
'TEM Cells For Dummies'.  I wrote to the vendor, but they haven't responded. 


On a slightly different note, has there been any progress for accepting
emissions measurements from  reverberation chambers (IEC 61000-4-21)?

RE: Heart pacemakers - Vulnerability to EM

2004-11-19 Thread owner-emc-p...@listserv.ieee.org 
I don't know what the standards call for but it is quite possible for a person
to be subjected to an E-field exceeding 500 V/m very near to an amateur radio
station. This is the field at my operating position when I am transmitting at
1.8 MHz. A cell phone held close to the body will cause a field, at the body,
of over 30 V/m.

Hi all

 

Heart pacemakers may be vulnerable to Electro Magnetic energy.  Has anyone
idea about safe immunity levels ? about relevant standards regarding this
matter ?

 

Thanks !

RE: NEBS Compliance of Single ATCA card

2004-11-19 Thread owner-emc-p...@listserv.ieee.org 
Hello Duncan,

Although I don't have an answer, you might also want to post this at the
NEBS WEB Group.  It is located at:

http://groups.yahoo.com/group/nebsweb

Somebody there may be able to assist you as they all deal with NEBS issues.
This was formally the NEBS Forum on IEEE but was migrated to a Yahoo group
in September.

Good Luck,

Jim

Subject: NEBS Compliance of Single ATCA card


Group,

One division of our company is looking to design an ATCA card that is
designed to be installed in telco applications, although not directly
connected to a telco network. The card is to be sold as a single card
for systems integrators and therefore requires a chassis or frame to be
able to work. The card is intended for use in ATCA applications and
because of its close proximity to telco applications it is highly likely
that our customers will expect some level of NEBS compliance.

Has anyone in the group had experience of designing a NEBS compliant
ATCA card, and If so do you have any advice or design pointers.

Also as far as I understand, NEBS is a systems level standard so our
single ATCA card cannot comply with NEBS in its own right. Is this
correct?

>From a quick scan of the internet, It appears that most card
manufacturers claim to meet NEBS on single cards, one can only assume
that they have conducted tests relevant to the card i.e. they test to
ensure that the card would not fail NEBS when installed. Either that or
they have tested the card in a NEBS compliant chassis.

Our plan is to specify and design the card to meet the relevant NEBS
requirements and to do basic tests. We would then work with any systems
integrator to provide support for the card for the NEBS testing of their
complete system (in which they have fitted our card). The claim would be
that the ATCA card was 'designed to comply' as we would not have tested
the final system.

Are there any ATCA card manufacturers or systems integrators who may be
able to comment on what they would design for or look for when
purchasing such a card? Any comments or guidance would be grately
appreciated.

Regards,
Duncan.

Re: International power supply required markings

2004-11-19 Thread owner-emc-p...@listserv.ieee.org 
David,
 
See answers in body of your message. 

David Heald  wrote:

Greetings all,
I wanted to run this by everyone to see if there is some consensus out there
(not that it would matter if we're all wrong anyway, but...)

We know of the following countries that require special markings for power
supplies (normal wall plugged, few amp consumer grade type - nothing special
here). This list is a little over a year old, so I want to make sure nothing
has changed:

Argentina - You need the S Mark such as TUV Rheinland S Mark
Australia/New Zealand - RMA Mark
Canada (often combined with some US mark even if no specific mark) - Correct
China - CCC Mark
EU - CE needed
Germany (GS Mark) - Not needed but good for sales
India - required
Israel - required - SII cert (not Mark) or Tamas
Mexico - NOM required
Russia - PCT Mark required
Singapore - required
South Africa - LoA
South Korea - KET + MIC
Taiwan - BSMI approval 
Ukraine - not sure!
US (just your normal safety agency mark) - correct
I have recently heard of a required mark in Malaysia (SIRIM mark), but I am
unsure if it is a hard requirement or just suggested/available. Surfing SIRIM
offered no answers - any first hand knowledge out there?

Also, does anyone know of any others that I'm missing?

 

Peter: Depends on the country. For example you will need the PSE Mark for
Japan.

I believe that all of the NDFSemko marks have been supplanted by the CE mark,
and a bunch of the newer EU members dropped their special requirements, so my
major concern is developing requirements in Asia that may have slipped in
under the radar.

I'll try to investigate any feedback and post a followup message later...

Best Regards,
-Dave Heald
