Transient/Surge/Lightning Standards for DC power equipment
Hello group, I was wondering if there is a specific standard written for testing DC powered equipment powered from a centralized DC power source ( Rectifier, battery ,etc. and also if there is a specific standard that is written for Antenna cables that carries RF signal from outdoor units to Indoor ones. The closest thing I got across is the ANSI C62.41 (IEEE 587 formally), IEC 1000-4-5. -- Thank you very much for your time Sincerely, Sarmad Albanna Compliance Engineer Hughes Network Systems (ph) (301) 428-5705 . - This message is coming from the emc-pstc discussion list.

class x + class x = class x
Hi there EMC/PSTC folk: There's been a number of discussions here about the validity of "Class X + Class X = Class X" in the various FCC and CISPR EMC requirements. Bypassing the whole "is it appropriate" question, where exactly is it written that this is acceptable? Is it written in the standards themselves? I'm mostly involved in working with our system HW design to make sure it passes, and haven't gotten much involved at all in the reading and interpretation of the actual standards, or interfacing with the agencies, i leave that to our Regulatory Affairs group. As such, I haven't personally read the standards myself (yet!), so pardon the basic-ness of my question ;-). Unfortunately, I'm starting to need to know this sort of thing, and need to start arming myself with standards and supporting documents. if someone could point me to the appropriate document (if not written in the actual standard), or section of the standards so i can look this up, i'd be greatly appreciative. I'm mostly only interested in CISPR 11A (EN5011A), but wouldn't mind pointers for FCC Class A as well.

Santa Clara Valley December IEEE EMC Society Meeting Notice
Hi everyone, Just a reminder that the SCV IEEE EMC Society Meeting will be held 8 December - dinner and technical presentation both at Auspex. Menu choices will include prime rib dinner, vegetarian tortellini, and some traditional holiday dishes. The Product Safety Society will be meeting jointly with the EMC Society. December 8, 1998 Where - Dinner 5:30 - 7:30 PM Auspex Cafeteria, 2300 Central Expressway, Santa Clara Technical Presentation 7:30 - 9:30 PM Auspex, 2300 Central Expressway, Building A, Santa Clara, CA Speaker/Topic - Neven Pischl, Bay Networks, "A New Common-Mode Voltage Probe for Predicting EMI from Unshielded Differential-Pair Cables" Details --- On December 8, the Santa Clara Valley Chapter of the IEEE EMC Society will hear a presentation by Neven Pischl of Bay Networks on "A New Common-Mode Voltage Probe for Predicting EMI from Unshielded Differential-Pair Cables". Common-mode (CM) currents on I/O cables are primary sources of EMI in many electronic devices. Measuring the CM voltage at the I/O connectors can be an alternative to measuring CM currents. Sources of CM currents and voltages are discussed, and a CM voltage probe for prediction of the EMI levels from unshielded differential twisted-pair cables is described. CM voltages at the RJ-45 ports were measured and correlated to the 10m E-field levels of 8 DUTs. A CM-voltage level that corresponds to the EN 55022 A limit has been derived. This allows the prediction of radiated emissions based on CM voltage measurements at the connectors. This bench-tool can be instrumental in reducing the time and cost of troubleshooting EMI problems. - This message is coming from the emc-pstc discussion list.

Re: 1000Base-T (IEEE 802.3ab) vs. EMI on UTP (Unshielded Twisted Pairs)
I'll concur with Don, but as discussed at the IEEE 802.3z Gigabit Ethernet Task Force meeting in Irvine, California on March 10-14, 1997, this was apparently briefly discussed. The full text is at http://grouper.ieee.org/groups/802/3/z/public/minutes/Irv0397.txt I quote only the important part ... "Cable shielding was discussed and it was explained that two shields are required to meet radiated emissions requirements. This configuration easily passes "Class B"." At another site, http://www.anixter.com/techlib/vendor/cabling/lan1000.htm it is "suggested/hinted/implied" that compliance either for emissions and/or especially with balance on UTPs, the burden of compliance rests not on thy humble standard when considering all possible applications. Compliance rests with thee. Regards, Doug At 12:05 PM 12/7/98 -0800, Donald Kimball wrote: >The IEEE 802.3ab defines the new Gigabit Ethernet Standard (i.e. >1000Base-T).

Signal Line Output Surge Protection
One of our products required surge protection on a transmit output line to comply with a UL requirement. The designer chose an MOV across the differential output. When we performed a radiated emissions measurement, we found the previously compliant design to be "screaming" (~ 15 dB over the limit). Removing the MOV resolved the EMC problem, but then we have the UL problem. The protection we were looking for was 120 V clamp, capable of handling a 3 joule test with a peak voltage of 2400 V applied. Just curious, has anyone had a similar situation? A particular supplier indicated that others had reported MOVs to be disastrous from an EMC perspective. MOVs appear to be a device with a general rule of thumb "don't use on 'signal' lines". Any experiences you would like to share? What was your solution? Regards, Don Umbdenstock Sensormatic - This message is coming from the emc-pstc discussion list.

Re: Directives
Stewart, here are copies of the LVD and EMC Directives that I picked up off of the web somewhere (??). The copyright notice at the beginning does state that they are distributable, courtesy of Mr. Nick Rouse, provided that they are not modified (please read). I think that some 'Informative Annexes' with lists of 'EN' standards, the names and EEC agencies and the odd illustration are missing, but the text is more or less complete. Could you please post the EMC Directive Guidelines you mentioned (if complete) or where I might find them?? Note that these Directives essentially only say that "thou shalt produce a safe product that does not cause nor is it or is susceptible to electromagnetic interference". You must apply product specific and/or generic standards to show that you are appropriately compliant, and declare conformity to those as well. For example, the ITE Safety Standard, EN60950 (if appropriate), and the Generic Emissions and Immunity Standards EN50081-1 and 2 and EN50082-1 and 2. These (-the latter), in turn call up Emissions and Immunity TEST Standards, such as EN50011, 22 and the EN61000-4-x Series, respectively, which tell you exactly what tests you need to do. Simple, right? In Compliance Assessment Seminars I hold for local Industry, I present this as a pyramid, with the Directives at the tip, and the actual test standards at the (very wide) base.

EN55022 Level determination
I have attempted to post to the "virtual conference hall" a few times and nothing seems to be happening. So I figured I would try emailing emc-pstc directly. If several, similar messages should appear, I apologize in advance. Our Company has been shipping a terminal product (office equipment) into the EU for years. This product is compliant with CISPR22 level "B". Prior to my involvement (or, for that matter, any of the current regulatory staff), the decision was made to ship "B" product to avoid the need for VDE witness testing as well as the mail in card for our German customers. We understand that the need for the card and witness testing when qualifying product to level "A" has passed. However, since we have no recent understanding of level "A" (and a need to ship level "A" product), we looked at the relevant documentation and asked around. In the USA, it's pretty straightforward: home = B; office/industrial = A. We did not see such a clear distinction regarding the European Union. Matter of fact, one of our trusted consultants insists that we cannot ship level "A" equipment of this type into the EU. Another source says it's ok as long as the user's manual has a statement which says, in effect: "This is a level A product and may interfere...if it does, take measures to correct it".

Bill, you may want to go to the following URL http://www.conformance.co.uk/CE_MARKING/CELOGO/ce_logo.html It has the CE mark in many formats. I advise clients to put the CE mark on each product that makes up a system.

Re: Bitmap CE Symbol
Try http://www.conformance.co.uk/CE_MARKING/CELOGO/ce_logo.html. where you'll find the logo in a dozen or so different formats. I'd be interested to know if it helps you out.

RE: Bitmap CE Symbol
Bill, Check out www.conformance.co.uk. I believe there are some downloadable symbols there. I would suggest that the CE mark is placed on the sub assemblies, components are outside the directive, and all packaging.

Directives
Hello Everyone...! I have a couple of questions concerning the EU and directives and how they apply to ITE . 1) I have in my hands guidelines on the application of Council Directive 89/336/EEC. I retrieved it from the Europa server but have been unable to find other such documents, LVD for example. Does anyone know the proper technique to search for the main text of the directives (not the amendments, I have found a zillion of those). 2) Can anyone shed some light on which directives (Safety, EMC, etc.) would apply to automobile mounted ITE. Any help is most appreciated ...Happy Holidays... Judd Stewart 619-623.6639 - This message is coming from the emc-pstc discussion list.
