RE: Job Opportunity - Maryland
I've been getting quite a few emails regarding age discrimination regarding the email below. Just so it's known, the recruiter did not place this requirement on the job, nor did I. The requirements are poorly written, no question. My intent was to allow someone the opportunity to gain employment and feed their family. The requirements seem to be the result of a conversation, not a legal briefing. I have no idea who the company is, nor do I care, but for the sake of those in the midst of a job search, they are who this was intended for. I will certainly edit the next request I get and provide less information than I did this time, but I think it's important to take this email for what it was, trying to help someone get a job.

Re: electrochemical potentials
I think you are confusing data and standards. Electrochemical potential is data that goes back over three centuries when Voltaire and others started measuring it. The first place I ever saw it published was in my father's copy of the Handbook of Chemistry and Physics, 19th edition. by the Chemical Rubber Company. I used the log and trig tables in the CRC when slide rule accuracy wasn't good enough. BTW slide rules are analog calculators. Fred Townsend John Woodgate wrote: I read in !emc-pstc that david_ster...@ademco.com wrote (in 2DF7C54A75B dd311b61700508b64231008db5...@nyhqex1.ademconet.com) about 'electrochemical potentials' on Wed, 15 Oct 2003: I am reviewing some dissimilar material combinations in an earthing path. I have reviewed a lot data available on-line and in a few reference texts. I would now like to better understand the origins of Table J.1 in IEC60950. Does anyone know where the data on which Table J.1 is based originated? I didn't receive the original message. I found, several years ago, an error in the table and at that stage tried to find out where it came from, without success. Was it a reference standard or data from an industry association? Something else? It doesn't seem to come from another standard. I am finding Table J.1 might be useful as a reference, but little else. The types of alloys referenced can have electrochemical potential differences relative to one another that vary 10% or more from the values shown in the table. I'd appreciate any input you might have. It's not actually much use at all. These potentials give an indication of the probability of electrolytic corrosion under *laboratory* conditions, with no contaminants. They don't give reliable indications in the real world, where contaminant ions, such as chloride, sulfide and sulfate, occur. Having said that, avoiding combinations that involve high potentials minimises the probability of serious short-term corrosion, but by no means guarantees acceptable results. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?

Re: Job Opportunity - Maryland
Not really buying this argument. I too spent a second considering that they were looking for some sort of experience being taught only in the last 20 years or something. But with even the slightest of thought it would have been stated completely different. EG Need college experience in ASIC development etc. Even if I met the qualifications as stated this opportunity goes straight into the garbage. It tells me a lot of things that I'm sure the manager/company didn't want to say about the work environment.

I have reviewed a lot data available on-line and in a few reference texts. I would now like to better understand the origins of Table J.1 in IEC60950. Does anyone know where the data on which Table J.1 is based originated? I didn't receive the original message. I found, several years ago, an error in the table and at that stage tried to find out where it came from, without success. Was it a reference standard or data from an industry association? Something else? It doesn't seem to come from another standard. I am finding Table J.1 might be useful as a reference, but little else. The types of alloys referenced can have electrochemical potential differences relative to one another that vary 10% or more from the values shown in the table. I'd appreciate any input you might have. It's not actually much use at all. These potentials give an indication of the probability of electrolytic corrosion under *laboratory* conditions, with no contaminants. They don't give reliable indications in the real world, where contaminant ions, such as chloride, sulfide and sulfate, occur. Having said that, avoiding combinations that involve high potentials minimises the probability of serious short-term corrosion, but by no means guarantees acceptable results. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?

Fw: centrifuges and the MDD
Hi to all involved in this discussion, This is the relevant definition from the IVD (In-vitro Diagnostics Directive - 98/79/EEC). Sorry about the length of the quote. in vitro diagnostic medical device` means any medical device which is a reagent, reagent product, calibrator, control material, kit, instrument, apparatus, equipment, or system, whether used alone or in combination, intended by the manufacturer to be used in vitro for the examination of specimens, including blood and tissue donations, derived from the human body, solely or principally for the purpose of providing information: - concerning a physiological or pathological state, or - concerning a congenital abnormality, or - to determine the safety and compatibility with potential recipients, or - to monitor therapeutic measures. Specimen receptacles are considered to be in vitro diagnostic medical devices. 'Specimen receptacles` are those devices, whether vacuum-type or not, specifically intended by their manufacturers for the primary containment and preservation of specimens derived from the human body for the purpose of in vitro diagnostic examination. Products for general laboratory use are not in vitro diagnostic medical devices unless such products, in view of their characteristics, are specifically intended by their manufacturer to be used for in vitro diagnostic examination; Having read this, it seems to me that if the version of the centrifuge has any characteristics that make it intended by their manufacturer to be used for in vitro diagnostic examination, then it falls under the IVD. If not, and the same model is also sold for non-medical use, then its LVD.

PVC in Medical Devices
Are there formal requirements requiring that PVC (Poly Vinyl Chloride) NOT be used in medical device materials? If so, what are they called, and can there be exceptions to these rules. From my understanding, there are only informal ones that medical device manufacturers should adhere to for example when selling in Europe. The insulating shrink material used on Nickel Metal Hydride batteries consists of PVC. Almost all battery suppliers use the same shrink material sold in many parts of the world. It would appear that this may be a concern. Thanks Peter Valentyik This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.

Correct label for DC input/output port
Group We're designing a piece of mains powered IT equipment for use by the general public, that will be sold in a number of different countries. The unit has a single DC-jack socket that can be connected to an external battery box. Whilst powered from the mains the unit will charge the battery and when mains fails it will accept power from the battery. we currently have+ -(o- - 12V 1Aabove the socket - and there's not much room to add anything much bigger We wish to discourage users from plugging in an external dc supply ( from a solar panel for example) as the unit will not work off an external DC supply alone ( it will only start up from the mains). I'd welcome suggestions as to the best way to label the socket. regards Charlie Blackham Approvals Manager Airspan Communications Ltd

RE: electrochemical potentials
From: David Sterner Sent: Wednesday, October 15, 2003 5:45 AM The voltages are derived from electrochemical reaction data referenced to a hydrogen electrode at 298.15°K and 101.325 kPa. Thank you for your response, David. I am entirely uncertain that the hydrogen reference electrode was used to product the data in Table J.1, since it is a less practical reference electrode than others. The hydrogen reference electrode is uniquely defined to provide the 0 V reference point and is defined so at _any_ temperature, though the pressure is always 1 Atm. There are several other reference electrodes, including calomel, mercury/mercury oxide, mercury/mercury sulfate, silver/silver chloride, copper/copper sulfate and the 'nonaqueous' silver/silver nitrate. The voltage references for these latter reference electrodes also have a dependency on temperature, ion concentration of the salt and the normality or molarity of the solution used as the electrode solvent (KCl and HCl seem most commonly used). Be that as it may, the relationships between standardized reference electrodes are reasonably well defined and calculable. It is possible to use data from one reference electrode (at a given molarity and temperature) to predict a result using another reference electrode (at a different molarity and temperature). Also, since half-cell voltages are used, the choice of reference electrode should not have all too great an effect on the ultimate potential difference between metal species, as the reference electrode voltage cancels out in the calculation. Another dependency is the electrolyte surrounding the specimen electrodes. Both chemical constituents used and their concentration in solution influence the results. The resultant potential differences between specimen electrodes varies more significantly for electrolyte differences than it does for which reference electrode is used. I have also found that laboratory results are not necessarily representative of real world applications. For instance, different potentials are derived for flowing sea water electrolyte from those for low velocity, poorly aerated sea water. The most important lesson learned so far is to not rely on electrochemical potential half-cell data that does not specify both the electrode and the electrolyte. These are published in various references, including the CRC Handbook of Chemistry and Physics. You consider all possible reactions among the metals and decide which reactions are likely to occur spontaneously. Unfortunately this data does not include alloys. David I have a CRC Press, Handbook of Chemistry and Physics and found it of little use in this particular instance. The electrochemical potentials shown are geared toward battery couples. There are other issues recently brought to my attention that I will also pursue to better understand the topic. Regards, Peter L.

Tarver [mailto:peter.tar...@sanmina-sci.com] Sent: Tuesday, October 14, 2003 2:19 PM To: PSTC Subject: electrochemical potentials I am reviewing some dissimilar material combinations in an earthing path. I have reviewed a lot data available on-line and in a few reference texts. I would now like to better understand the origins of Table J.1 in IEC60950. Does anyone know where the data on which Table J.1 is based originated? Was it a reference standard or data from an industry association? Something else? I am finding Table J.1 might be useful as a reference, but little else. The types of alloys referenced can have electrochemical potential differences relative to one another that vary 10% or more from the values shown in the table. I'd appreciate any input you might have. Regards, Peter L. Tarver, PE Product Safety Manager Homologation Services Sanmina-SCI Corp.

RE: centrifuges and the MDD
Paul, If the centrifuge is used for blood, then it is covered under the MDD. It is classified under Rule 3 and is a Class IIa device. See the MEDDEV Guidelines for the Classification of Medical Device. Centrifugation of blood to prepare it for transfusion or autotransfusion.

Can anyone point to any info that specifically calls out centrifuges as product covered under the MDD? I have found only a very vague description of covered products but nothing that conclusively includes centrifuges as a product covered under the Medical Device Directive. Best Regards, Paul J.

Joint EMC Society and NPSS Meeting Next Week on Wednesday, October 22
All, There will be a joint Northeast Product Safety Society and EMC Society meeting next week on Wednesday, October 22, at EMC Corporation's Customer Briefing Center at 42 South Street in Hopkinton, MA. A social hour with light refreshments will begin at 6:00 PM and the technical meeting will start at 7:00 PM. We have two technical presentations this month with one predominately EMC related and the other product safety related. The first technical presentation will start at 7 PM with an expected 45 minute duration followed by a brief Q A time. Our second technical presentation will start around 8 PM or immediately after any questions for our first speaker. If you will be in the area, please feel free to join us as NPSS or EMCS membership or advanced notice is not required. Our first speaker, Dr. Cheung-Wei Lam, is a Senior Engineer at Apple Computer. Dr. Lam will present trade-offs and guidelines for signal integrity design versus radiated emission control. For engineers responsible for both disciplines, an in-depth understanding of the similarities and differences between the two is even more important. In this presentation, key signal integrity and EMC concepts will be reviewed. Design considerations in the two disciplines will be compared and contrasted at the chip and PCB levels. Dr. Lam is engaged in IC, PC board and system level EMC RD at Apple Computer and has implemented an EMC design and analysis process at Apple to facilitate on-time compliance at lower cost. Prior to joining Apple, he was a co-founder and Principal Engineer of Transcendent Design Technology and worked in Viewlogic's Advanced Development Group (formerly Quad Design Technology). During his years in the EDA industry, he has played key roles in the design and development of EMC, signal integrity and ground bounce analysis software tools. Dr. Lam received his B.S. degree in electronics from the Chinese University of Hong Kong, and his S.M. and PhD degrees in electrical engineering and computer science from MIT. He has served on the IEEE EMC/S TC-9 Computational EMC committee and the SAE EMC Modeling Task Force committee. He has given numerous papers, seminars, workshops, tutorials, and training courses on various EMC and signal integrity topics in the US, Europe and Japan. He was a co-recipient of the best paper award at the 1996 IEEE International Symposium on EMC. In 2002, he was appointed to serve as an IEEE EMC Society Distinguished Lecturer and is listed in Who's Who in Science and Engineering, Who's Who in America, and Who's Who in the World. Our second speaker, Mr. Timo Venalainen, is the Technical Manager of Electronic Products at CSA-International. Mr. Venalainen will present an overview of new requirements in IEC 60065-7th edition, and a progress report on the TC 108 work under way on the Hazard-Based Standard. Since the New Hazard-based Standard will replace both 60950 and 60065, this topic will be of particular interest to anyone involved with product safety certifications. Mr. Venalainen has been involved with certification of audio video products at CSA for 31 years. He has been a Senior Engineer for over 18 years. Mr. Venalainen is a member of IEC TC 108 committee and working on the maintenance of IEC 60065. He is also assisting in the writing of the new Hazard-Based Standard to cover IT and AV Equipment. The 2002 NPSS meeting schedule is available on the NPSS website at http://www.nepss.org/meetings/NPSS2003Calendar.htm. Further information about the Northeast Product Safety Society and how to become a member is available at http://www.nepss.org.
