Job Opportunity - RadiSys - Portland, Oregon
Greetings PSTCers, I posted a brief note a couple of weeks ago, but wanted to provide more detail on another opening we have for an experienced compliance engineer. RadiSys is a manufacturer of embedded computer products. This position is at our Hillsboro, Oregon location and supports design teams worldwide. The ideal candidate must be very comfortable working with a wide range of computers, software, operating systems and electronics. They must be able to read schematics and provide a technical analysis based on applicable standards and test targets for the program. They must be ready to jump in and operate the equipment being tested (with support from the development team) and are frequently in the position of demonstrating acceptable operation to test lab personnel. Most of our products obtain safety certifications to IEC/EN/UL 60950-1 and EMC approvals to EN 55022/24 and FCC Part 15. We have significant NEBS project work (Telcordia GR-63/GR-1089 and ETSI 300 386 / 300 019). And frequently have to support a broad range of customer requirements for shock/vibration, temp/humidity and other areas. Realizing that not everyone needs to support safety, EMC, NEBS, Environmental, etc., we’re looking for someone who will hit as broad a range as possible. Existing members of the team and others within our R&D organization support these activities, as well. This engineer will support projects from initial design to end-of-life – with the bulk of their time focused on initial certification of the product. Requirements: * BS degree or equivalent * 12 years of experience in the areas described above * Solid track record working on broadly cross-functional teams * Comfortable supporting multiple projects concurrently and performing hands-on testing The posting for the position is here: http://www.radisys.com/careers/jobs_detail.cfm?jobsid=356. It has additional information, as well as links to broader information about the company, benefits, etc. It’s also posted on Monster. Please e-mail me if you have questions or concerns.

120V Ground Faults
Robert, >From my experience, I think you will find that arcing ground faults are inherently high-resistance in nature and, while dramatic, do not necessarily pull significant amounts of current. Most 15 amp breakers will likely require several seconds/minutes to blow at 60/30 amps, which is what you'd get with a 2/4 ohm arc. In reality, I wouldn't be surprised to see something more like a 10-20 ohm figure being used for this type of phenomenon, which would allow a 15 amp breaker to arc virtually continuously (i.e. the home arc-welder). The fact that arcs are drawn - and sustained - at 120 volts is, I believe, relatively rare. Higher voltage systems (and GFCI outlets) have ground fault systems that rely on the detection of zero sequence (neutral leakage) currents. My understanding is that the decision to require this type of protection on 480 volt systems over 1200 amps was largely due to the increased likelihood they'd be able to draw and sustain an arc, as well as the damage that can be caused at these higher power levels (balanced with the concerns of cost-effectiveness of installing them more broadly). I feel they drew the line in an appropriate place. In my experience, while problems, such as this, do arise, the frequency and relative damage caused by them is relatively small. I think you would have seen a change (like the addition of GFCI about 25 years ago) if the case were otherwise. You should be able to add zero sequence current sensing to your household panel, should you care to do so, for ~$500, but where out-of-the-box systems exist for 480 volt systems, this would need to be a custom design amploying the combination of a sensor relay and a shunt-trip breaker. Of course any nuisance trips you may experience similar to your GFCI would take down your main You can buy a LOT of GFCI breakers for these dollars. Caveat Emptor/Engineer.

Re: Source for Acoustic Simulation Software
John (and Group): Sorry not to have further clarified this point in my original posting. I am indeed interested in simulating the noise generated by fans (primarily) and other sources within a design. Perhaps the most familiar application is for a 2m tall telecom frame that will need to meet the requirements of GR-63 for NEBS. I'm fairly certain there are similar requirements in ETSI 300 019, but I'd have to check. We're also seeing other acoustic specs that are similar in application for other designs ranging in size from a "pizza box" (~half the height of a desktop PC) to custom medical or other equipment. Our approach to date was to be as prudent as possible in the original design with respect to acoustics and filtering on our fans and make any modifications as needed once protos were available to measure the actual performance. Our mechanical engineering group is interested in taking a more deliberate approach in the future, if it's reasonable to consider doing so. I'm assuming from the lack of other responses that it is either my lack of clarity in this respect or the fact that this may not be done elsewhere that I haven't heard anything. Hopefully, I've alleviated the first option with this further explanation.

Source for Acoustic Simulation Software
Group: I have a curve ball to throw to the group. Our mechanical engineering groups is looking for software that we can use to simulate the acoustic performance of a design prior to fabrication. We're very comfortable performing thermal and airflow simulations, but are interested in also pulling acoustic simulation into things if possible, since we're running into tighter and tighter acoustic performance specs in denser and denser packages. Compliance to GR-63 and other specs is becoming all too commonplace If you're aware of any resources we can consider for pre-fabrication simulation, please answer to the list or e-mail me separately.

Product Safety Approvals in Oregon
Ken, I couldn't disagree with you more. As a Professional Engineer in Oregon who previously worked for an NRTL, I can assure you that the current state law does not permit individual PE's to field label equipment - nor has it ever, to my knowledge. Equipment approval activity is limited specifically to labs approved by the state of Oregon. If there is a PE not associated with a state-approved lab that is conducting this work, I would doubt whether it met the requirement of the current law. Intel, Weyerhaeuser and others have argued unsuccessfully for this approach for years. With regard to the original question, NRTL approval (through OSHA) is a first line approval for most of the larger labs. While it may be possible to obtain approval with some jurisdictions without NRTL status, I would be cautious about working with such a lab. NRTL approval can then generally be leveraged to obtain approvals in specific jurisdictions. Some jurisdictions accept the Federal NRTL designation as sufficient for approving products in their area (some, such as Texas, have little oversight of such activity in any case). Others, like Oregon and North Carolina, as well as probably the cities of Los Angeles and Chicago require labs to meet additional requirements, as well as support periodic audits of their activity in the jurisdiction. Even within Oregon, however, the playing field is not perfectly level in the application of the requirement for existing law. The Portland Metropolitan area sees far more enforcement of these requirements than the rural, southeast corner of the state, for instance. This may mean that in addition to issues where the equipment can be installed in a facility in Austin, TX without further evaluation, while Portland, OR may require it, you also have the potential of installing a system in a community within Oregon where these requirements are not universally applied, while you will still run into difficulty within Portland (one of the most consistent jurisdictions in the application of these requirements). In the case of the equipment referenced by Mr. Selva, I would encourage him to obtain the list of labs currently approved by the State of Oregon. This can be obtained on their website ( http://www.cbs.state.or.us/external/bcd/tag/advisory/fieldevalfirms.pdf). This document contains both the list of labs - for listing - and field evaluation firms that are approved by the state. You will note that there are no individuals, such as PE's listed in this document. The engineering firm Edan Engineering is the closest to this mark, but I believe you will find that their pricing will be similar to the other firms and that their activities follow the same requirements placed by state law. Products listed by an approved lab are generally accepted as long as they carry the listing mark from the lab. Products that have already left the manufacturer's site without a listing mark will be required to be field labeled. Recognize that labs are approved for different categories of equipment, so the correct category will have to be approved for the lab that is selected to perform the work. In short, however, I would encourage you to visit the website in question and select the lab to perform this work with extreme care. As someone who has worked in this field for ten years (and is now on the other side of things as the manufacturer), it is very easy to get lost in misinformation about the specific requirements, especially when separated physically by 6-8 time zones and several thousand airmiles. I would categorize the comment about PE's performing equivalent approvals to be in the category of misinformation. Finally, I will mention that for a product that is not exceptionally unique - that is, something that is produced in significant quantity - the view has frequently been - and the law is written such - that this type of product should be listed by an NRTL instead of being field evaluated. If the product in question - a spectrometer, I believe - fall into this category, which I would think is likely, this could be an additional barrier to using field evaluation for the approval of thie equipment. This has been an issue that is coming up more an more in recent years. If you have specific questions about this process or wish to discuss individual labs in Oregon, I would encourage you to contact me directly either via e-mail or at the phone number shown below.

Power Transformers and the applicability of -3-2 and -3-3
Chris, Sorry to keep -3-2 in the conversation, but hopefully you'll get the point. I still have questions pertaining to it, so I've couched my answer in this context. I'll take a swing at this with the caveat that I don't pretend to be the world's expert on this subject, but I'm running into it a great deal with -3-2 and have spent a lot of time trying to make sure I'm aware of the requirements and potential exceptions. I'm also not on the committee that wrote the standard, as Mr. Woodgate, the author of the excellent article you reference, is. And my third strike is that I'm an American, so my interpretations of European requirements are, by default, to be considered to be questionable at best. Now, on with the countdown... For most residential customers (Bill Gates and Larry Ellison excluded), power enters your premises at 120/240 volts (230 volts in the EU). This is the low-voltage electricity supply referred to in the -3-2 and -3-3 standards and, thus, any electrical equipment in this setting falls within the scope. For some commercial customers, they have the same situation - low voltage (230 in the EU) enters your facility and, as such, applications in this setting would also be considered to fall within the scope of the standard, since the potential exists that harmonics they generate would be present on the power system accessible by others on the same low voltage transformer. For larger commercial customers (and Bill and Larry), power is delivered to the campus at medium or high voltages. In North America, this would be 2300 volts, 4160 volts, 15kV, 69kV, 115kV, 230kV, etc. It is generally more efficient for them to buy things like this and easier for the utility company, as well. Think of the aluminum smelter plugged into a 120v wall outlet... For these last customers, the case can be made that the 120 volt wall outlets (230 in the EU) that exist on their campus (e.g. in offices, kitchens, etc.) are not part of the PUBLIC low-voltage electricity supply (i.e. their neighbor company isn't running off the same low voltage transformers in the same way your neighbor at home likely is). These applications are connected to the public power distribution system at medium or high voltages and harmonics and flicker exposure from equiment are mitigated by that transformer. They have their own PRIVATE low voltage electricity supply system, and, thus, the provisions of -3-2 and -3-3 do not apply to this application. (Obviously, owners of these private distribution systems should be mindful of the issues covered in the standards, but will likely tolerate more than you might tolerate of your neighbor). The difficulty that I have is that my company needs to assume conservatively that all applications of our product fall within the settings that would require the PFC-compliant supplies to be used. (1) Is there a satisfactory way to identify those customers who fall into the latter category and be able to ship equipment that do not meet the new requirements if they make the argument that they don't apply to their application - either via waiver or similar means? (2) Am I correct in reading between the lines of Mr. Woodhouse's article that since my product "can conceivably" be connected to the public system, it must comply, despite the end-use. Or am I reading too much into these requirements? It will be interesting to see how this will be enforced by customs officials and dealt with by members of this list.

Shipping RMA/Repair product to Europe
Group: I ran into an interesting curve on 61000-3-2/-3-3 that I wanted to make sure I dealt with appropriately. In our efforts to requalify our products for these requirements we handled most of the situations we could come up with, but the one area I missed was our Service department. We have product with an older supply that does not meet the requirements for -3-2/-3-3 that was returned to us for service late last year. After it has been repaired, our shipping group noted that this model was on our hold list due to the power supply requirements that went into effect 1 Jan 2001. I am assuming that we would have been able to ship the unit back into the EU through 31 December 2000, but now will need to bring it into compliance with the new standard (i.e. change the power supply to a compliant supply). Please let me know if what I've outlined above is correct or whether there are provisions for returns for service or other issues that we might consider.

Re: ESD Floor waxing
Dave, First, tread lightly in this area. I have seen some fairly tragic mistakes made by selecting the wrong stripper, wax or process. In the ESD arena, that was a test floor that had to be ripped up because the contractor used a stripper and wax combination that wasn't approved, which caused serious problems with the flooring. In a public arena, I have tested floors at a supermarket that were waxed with a particularly insulative wax, causing the triboelectrification from the carts to shock customers fairly badly. My experience in this area was with FIPS PUB 94, which was the Federal Information Processing Standards publication entitled "Guideline on Electrical Power for Automatic Data Processing Installations." I am under the impression that it contains data regarding the dissapative resistance to ground that is required for different classes of installations. It may be that there are other publications that would be of assistance for you, as well. A quick search on the web indicated that it was withdrawn in mid-1997 in part because it duplicated a voluntary industry standard. The ESD Association (http://www.eosesd.org) in the US and the The British Electrostatic Control Association (http://www.beca.co.uk) appear to be the best sources of information and would likely be a better point to begin your inquiry. >From memory, I am under the impression that you're looking for a resistance to ground on the order of 10,000 to 100,000 ohms. (The range on the ESD Assoc. website indicates between 10E4 and 10E11). This would allow any charge developed to bleed off through this resistance without posing a significant hazard to equipment or personnel. The standard referenced on the ESD Association website is EOS/ESD-S11.11. Volume resistivity measurements are different than surface measurements I have referenced above. There is also a reference to ANSI ESD S7 - Floor Materials - Resistive Characterization of Materials. The testing itself is generally conducted with an insulation resistance (i.e. megger) meter and two five-pound weights spaced at a specific interval (maybe 1m), as well as meaurements from one weight to ground reference. It's a very simple test. Please let me know if you would like a reference to a US firm that I know is able to assist you in this area.

Need for Sources for filtered PS/2 connectors
Group, I have a fairly urgent need for a filtered PS/2 connector. The component we are currently using is no longer available. While I'm mainly interested in companies, the specific impedance information is: Imp. Freq. 10 ohm 30MHz 17 ohm 50MHz 35 ohm 100MHz I have not been able to locate an alternative source for this type of component. Most of our designs have the filtering on the board, so all of my previous work with connectors has been in the unfiltered variety - which are much easier to find. I would appreciate any leads for an alternate supplier for a filtered connector. To keep list traffic down, if you would send me the information offline, I will post a summary to the list.

Makes me wonder, is CE marking of brains coming next? Would mine pass? Or will it need a major re-design to become compliant? Not sure I want the answers to those questions.

Re: Luminaires standard for USA/CANADA countries
Mr. Fini, I am unsure which of the following standards you need, however, here are the standard that I located searching on fluorescent. My original search on luminaires had no matches. 542 Lampholders, Starters, and Starter Holders for Fluorescent Lamps, seventh edition, 1994 A 935 Fluorescent-Lamp Ballasts ninth edition, 1995 G 1570 Fluorescent Lighting Fixtures fourth edition, 1995 G 8730-2-3 Automatic Electrical Controls for Household and Similar Use; Part 2: Particular Requirements for Thermal Protectors for Ballasts for Tubular Fluorescent Lamps first edition, 1996 J I am under the impression that UL 542 is likely superceded by UL 1570, but you would have to check with UL, since I am not familiar with the particular standard. I am under the impression that this is likely the standard you will need, but I am not sure. The equivalent incandescent standard is: 1571 Incandescent Lighting Fixtures fourth edition, 1995 A You can perform your own searches of these standards by going to: http://ulstandardsinfonet.ul.com/catalog/part1std.html and searching on the text of the standard titles. If your luminaires are not fluorescent or incandescent, you may require a different standard. It appears that Canada has adopted a version of IEC 598 with their new CAN/CSA-E598-1-98 series of standards. Information can be found on page 49 of their electronic product catalog, which you can download at http://www.csa-international.org/english/product_services/index_catal.htm While in the "English" version of their webpage, the catalog is bilingual with French included in the same document.

Rental Source for Broadband Source for Chamber Correlation
Group, I seem to be having difficulty trying to locate a vendor who will rent me a broadband source to use for precompliance chamber correlation measurements. I have a comb generator, but it is not providing me with enough information to ensure we have good correlation with the test house(s) that we have been using for final certification. I have been told that such generators may only be available for sale and if that's the case, I'm interested in vendors and approximate costs for that, as well. I have tried to use several of the "forums" set up by some on this list and basically come up empty. I have called several of the "usual suspects" for rental equipment without successful results. One issue is that I'm short on details of what specific equipment would suit my needs. I have briefly borrowed the use of a York CNE III and I know Laplace makes something similar. I have been told G-strip and Excel also have offerings in this area, but none of these seem to show up in rental firms' inventories. If you can give me further options in this respect, it may open some doors for me there, as well. If you could provide me with any assistance, I would appreciate it. I will also happily post a summary of my findings and pass them on to anyone running these "forums" for inclusion in their listings.

CE Marking requirements
Well group, if you care to help out another American confused by the specific requirements for Europe, I would appreciate it. I seem to be getting varying stories from different test houses as to what is required for one of our products. These are big enough players that pitting one against another is not something I want to undertake at this point. We currently manufacture a motherboard which is sold both by itself and with a chassis which includes power supply, hard drive and floppy. We are currently going through our internal EMC validation to ensure that we meet both FCC Class B and EN 55022 Class B levels. Our experience on previous products has been if we clear emissions, we haven't had problems in other areas, but we'll be testing to EN 55024 of immunity, as well. The issue arises when we discuss testing of the system versus testing of the motherboard alone. Within the US, the FCC regulations permit an additional 6dB margin for "open chassis" measurement, so long as those frequencies fall back within the class B levels with the cover on. This does not appear to be a problem for our product. We have been told by different parties that for Europe, (a) there is no requirement to test "open chassis" and that we can CE mark the board as compliant as long as we have shown that it can meet the class B levels within a chassis of our choosing and (b) we are still required to perform "open chassis" tests, however, there is no 6dB margin and the board will have to meet the EN 50022 class B levels with the cover off. We're having a little more difficulty making things work using the (b) approach. I am specifically concerned about staying far enough below the levels that we're not going to potentially pass today and fail 6 months from now due to a slight drift in tolerances of components, test equipment or test engineers' dispositions. I have the texts of the EMC directive, as well as the test requirements specified in the above documents and I'm happy to wade through them if you can point me in the right direction. I will be heading that direction in the next day or two if I don't receive a response. I'm hoping, however, that someone in the group can shave a few hours of exceptionally captivating reading from my life by pointing me in the right direction.

Information about sending equipment to Malaysia
I have a client sending semiconductor deposition equipment to a facility they recently purchased in Penang, Malaysia. The machine is designed for use on a 208 volt, 3 phase power system requiring approximately 100 amps at 60 Hz. The current system is five wire (including three phases, neutral and ground) and has 16kW worth of heating and 16kW worth of power supplies. They are interested in finding out 1) What, if any, approvals are necessary on this equipment for it to be put into use in Malaysia? And what firms or organizations can provide such an approval on "used" systems. 2) What are the operating characteristics of the Malaysian power system (e.g. 230 volts, 3 phase, 60 Hz., five wire system) 3) What problems do they need to be considering in order to be able to use this equipment in Malaysia? Any guidance on this matter would be greatly appreciated. Regards, Michael Garretson Sr. Compliance Engineer Electro-Test, Inc. - This message is coming from the emc-pstc discussion list.

CE Approval of equipment utilizing HPMs
I am forwarding this question on behalf of one of our clients. Please forgive the lack of detail in some areas. CE marking is not within the normal scope of my responsibilities, so my awareness of the specific requirements is not great. I would appreciate clarification of some of these issues so that we can provide the information to my client in the early stages of their design evaluation. It is my understanding that they are working with a US-based lab for portions of this work, but are not confident that they are being provided with accurate information regarding what requirements may exist to achieve CE marking of the equipment. My company is working with a manufacturer that is intending to send a piece of equipment to Ireland for the first time. The equipment is intended to be installed in a non-classified location, however it uses flammable liquid (hazardous) process chemicals (details unavailable at this time). I am under the impression that the manufacturer plans to assemble a Technical Construction File in order to demonstrate conformance with the applicable requirements of the pertinent CE directives. At this time, they intend to demonstrate compliance with the applicable portions of the Low Voltage, Machinery and EMC directives. Due to the hazardous chemical issues, it has also been suggested that conformance with 94/009 EEC may be required. I would appreciate it if anyone can provide me with guidance on whether this approach is reasonable or whether alternatives need to be pursued. Also if there are specific pitfalls that this manufacturer may encounter, please indicate where those may be, as well. If you require additional detail in order to assist my client with this matter, please let me know what information you require and I will pass the request on to my client.
