RE: CE - abbreviation
Amund,
I don't think the discussion reached a consensus. An early book on the
subject,
Chris Marshman. The Guide to the EMC Directive. 1992:IEEE Press,
Piscataway NJ 308p.,
identified 'Communauté Européen' as the reason for 'CE' (p11 of
Introduction).
Some explainations are anachronistic. The 'European Community' ('Community
European' in romance languages) was still 'European Economic Community' when
the symbol was created. Chris may be correct.

Hi all,
We had a short discussion last autumn about the abbreviation of 'CE'. Did we
conclude that the characters CE didn't mean anything? I have seen papers
recently that says CE is 'Communauté Européen', but we did conclude that it
was incorrect, didn't we ?

Manufacturer's I.D. for Europe
What are your thoughts on this issue? The prevailing ITE safety standards (e.g. IEC 60950) require markings that include the manufacturer's name, trademark, or identification mark (section 1.7.1). It is not uncommon for a manufacturer to allow another company to market their products under the 2nd company's logo. Often the 2nd company will retain the certified machine model/type number, but prefers no reference to the original manufacturer, including on the power rating label. In the U.S., manufacturer identification marks can be listed by UL in their Yellow Books. For example, in the case above, the original manufacturer's identity can be preserved by the use of a listed graphic, which is not obvious to someone buying the product through the 2nd company. In addition, the use of agency file numbers with their marks maintains traceability to the original manufacturer. However, in Europe, I am not aware of any means by which manufacturer's identification marks can be registered or listed. In addition, European safety agency marks are not required to be accompanied by file numbers etc. Therefore, replacement of the original manufacturer's name and/or logo with that of a 2nd party obscures any traceability to the original manufacturer. This may be acceptable, for as I understand it, the EU holds the responsible party as being the one placing the product on the market, i,e, not the original manufacturer.

Marine Directive, Annex of Standards, TC300 (?)
Is a member of or a person otherwise associated with TC300 work group on our EMCPSTC list that could assist or comment? We have products in design that could be applied to Marine applications. We'd like to design-in the EMC and safety requirements now. I believe the best approach would be to meet the Marine requirements first before any specific requirements of a marine society. At the moment we're finding the Marine Directive to be very incomplete. In contrast, several NB-level Marine Societies exist and they already have EMC/safety requirements. However, eash has different requirements and different continuous production requirements. (Some take IEC documents and deviate from the test requires slightly, enough to force complete retesting from similar test levels in the EMC Directive.) As of October 2001, committee TC300 was working on adding existing ENs to the Directive. Many fire control and other such ENs have been added. Presently the web page I consulted shows no norms covering electrical control/measurement equipment. We would like to see EMC standard EN 61326-1 and safety standard EN 61010-1 both be added to that list. (Both have identical scopes.)

Re: Chamber Doors
Can you share with us what experiences you have had with doors of your steel clad chambers? If you could share such things as chamber vendor, hinge adjustments, door maintenance recommended and performed, warranty claims and length of time without problems, that would help us understand the 1 year policy. Anyone have any interesting stories? Don, From the numbers you gave, I'd say the reason is, the doors are five times more likely to fail than the chambers. This is reasonable - they are the only things that move. And I'd say that the causes of failure are more related to installation practice and maintenance, than to design, so a one-year warranty will cover problems due to (say) being slightly mishung. Though workmanship should have its own warranty, if their team installs it. After a year, door failures are likely almost ALL due to maintenance or its lack, than to materials and installation. I've rarely seen folks doing monthly maintenance on the fingers that seal a door. That's MY two cents.

No specific war stories. Door shielding depends on homogeneity of conductivity across door-chamber interface. That can be degraded rapidly through misuse.

FW: Teslars???
Nick, Let's not lose sight of the original question: We have a customer that is concerned about how our product, laboratory equipment, will respond to electromagnetic disturbances from a high speed train that runs close to their lab. The customer states that the disturbance will be around 0.7-1.2 m Teslar. The B-field and H-field are related by the permeability, in this case, of free space. This relationship holds for all frequencies, therefore there is a constant relationship between flux density and field strength. From the perspective of designing a product to be immune from magnetic disturbances, the desired result is to limit the amount of flux passing through the victim loop and therefore reducing the amount of noise current in that loop. The effects of this noise current depend on the impedance of the victim circuit. The actual design solution is dependent on the characteristics of the victim circuit. From the original question, EN61000-4-3 covers frequencies from 80 MHz to 1 GHz and EN61000-4-6 covers 150 kHz to 80 MHz, while EN61000-4-8 covers power frequency magnetic fields. In either case, the .7 mT requirement is substantial and more info from the customer and more info about Joe's product is required to determine if there is a real potential problem. -Original Message- From: Nick Rouse [mailto:nickjro...@cs.com] Sent: Friday, February 08, 2002 4:08 PM To: emc; Mike Cantwell Subject: Re: Teslars??? To be pedantic, you are mixing units of two different quantities there Mike. Tesla and gauss are units of magnetic flux density, the B field Ampere/metre and oersted are units of magnetic field strength, the H field. Only in a vacuum does 1A/m generate a flux density of exactly 0.4 pi µT In air its pretty close but in ferromagnetic materials it can be thousands of times bigger. The field strengths mentioned in the original question are not all that outrageous. Most transformers, motors and generators with electrical steel laminations operate at peak flux densities of 1.4T to 1.7T within the core. At a boundary between two materials of different permeabilities the tangential component of H and the normal component of B are the same either side of the boundary. The amplitude relative permeability of electrical steels near their maximum working flux density is only about 300 to 800. So with the flux flowing along the core at a flux density of say 1.5T and an amplitude relative permeability of 500, you get a flux density close to the core surface of 3mT. While you are in the near field (distances small with respect to the size of the magnetic circuit) this will not drop very fast. in the far field it drops according to the inverse cube dipole law. Things are even worse at the corners. The flux does not turn smart right angles just because the core does and so the flux is not parallel to the core. This increases the flux density close outside the core. Worse yet are the effects of gaps. Laminations in transformers are commonly made in two parts that fit together to form the complete lamination. C T shape or E and I shape. This is done so that the winding can be put on the bobbin first and then the core built up. Where the two parts of the lamination meet up there is always a small gap the size of which depends on the quality of the laminations and the care with which the core is assembled. Good practice is to alternate the orientation of the laminations so that the gaps do not align but in some cheap devices the laminations are stacked up with the gaps aligned.These devices also tend to be those using poorly cut laminations. Gaps of half a millimetre are not unknown.they also tend to push the flux density up closer to the limit increasing the external flux even more because of the lower amplitude relative permeability Gaps in rotating machines can be even bigger . Since the flux crosses the gap almost normally the flux in the gap is the same as in the core 1.4T -1.7T At the edge of the core this flux bulges out into a fringing field. Fortunately this enters the far field dipole law at distances large compared to the gap length and width. Even so fields of tens of mT can be found within a few centimetres of the gap. So take a large poorly built transformer or solenoid and push the core hard up against the equipment housing and you could well exceed 0.7 mT nearby. Several metres from a train is a bit less likely but not impossible These figures should be borne in mind the next time you read about the dangers of the magnetic field from overhead power lines. I have several times seen building site welders sitting on their transformers with their testicles dangling over the gap and I haven't seen welders dropping like flies.

Re: Clean class B test bed
Greetings all, In my days at an EMC test house, we used Dell Dimension series P1 -133 to 200's and PII 233-300's with great success. I think Micron may have used the same case as well. The dells were opened daily but kept their excellent shielding for at least 2-3 years. Good luck finding one, but if you can find someone still using one of these at their desk, I'm sure you convince them to upgrade. The cases were plastic looking on the exterior with one side that slid off. The insides of 5 sides of the case were a metal chassis inside and the removable side panel had a thin metal panel resembling a huge springfinger panel. I think they refreshed the plastic on the outside when they came out with PIII's, but the inside was still pretty much the same.

Re: CISPR Compliant EMI Receiver/SA
Are there any opinion of EMI receiver from Schaffner? I am considering to get one receiver or spectrum analyser to cover up to 26.5 GHz. Cost is an issue and the most important is the services provided. The rep. of the famous brand of EMI reciver is not very good at servicing the test lab here. lfresea...@aol.com 02/08/02 10:30pm Hi all, I like to use a spectrum analyser more for diagnostics, and a receiver for compliance work. Of course I'm biased, but the Schaffner receiver currently covers 1 GHz, and the new version about to hit the streets goes to around 20 GHz. Both are CISPR 16 compliant. I personally feel they work best under software control such as Compliance 3. Best regards Derek Walton. --- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
