Re: [PSES] Mains voltage in Europe
Scott et al, As an outsider my recollection is that the decision to move from 220V in Continental Europe and 240V in the UK was enthusiastically voted in. The implementatin was scheduled to be a one volt change per year with both partine coming together after 10 years with a harmonized 220V everywhere. The Continental Europeean change seemed to proceed smoothly. I don't know of any issues. The UK change seemed in trouble from the beginning; uncertainty reigned. After a couple of years the UK gave up trying and abandoned the agreement to change the voltage. So now the Euro voltage is 230V everywhere except in the UK which is still 240V. Some European folks may have a better story but, I believe, the result is as presented here. The lesson learned here is that the system characteristics are deeply embedded in the infrastructure and changing something as basic as the voltage is anathema and plunges folks into an abyss from which they cannot recover (at least for islands). Don't hold your breath, Scott, awaiting this to get resolved. Perhaps someone would like to recommend that we change to a common frequency. I'd bet North Americans would like the rest of the world to adopt the more reasonable value of 60 Hz since it's tied directly to the way our clocks work. :) br, Pete Peter E Perkins, PE Principal Product Safety Engineer PO Box 23427 Tigard, ORe 97281-3427 503/452-1201 fone/fax p.perk...@ieee.org - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.

Not by Britain; we resisted for several years before a certain government official capitulated.

That simply isn't practicable and I don't see any reason to do it. The Continental Europeean change seemed to proceed smoothly. I don't know of any issues.

So now the Euro voltage is 230V everywhere except in the UK which is still 240V. Well, it's within 230 V +10 % most of the time in most places, but only a relatively few supplies were actually reduced: these were supplies to long rural feeders, where the voltage near the substation was high. I don't think there is any chance of the tolerance going back to +/-6%. It would be expensive and probably not bring any significant advantages. -- OOO - Own Opinions Only.

[PSES] Northeast Product Safety Society Meeting Wednesday, March 28th
All, There will be a Northeast Product Safety Society / CNEC Product Safety Engineering Society meeting on Wednesday, March 28th, at the Holiday Inn, Boxborough MA. A social hour with light refreshments will begin at 7:00 PM and the technical meeting will start at 7:30 PM. Bob Johnson ill be presenting a talk about temperature measurement and product certification with regard to thermal safety risks.. If you will be in the area, please feel free to join us as advanced notice or membership in NPSS or IEEE PSES is not required. Bob has worked in the product safety field for over 30 years at Digital Equipment Corporation, Motorola, and currently as a consultant product safety engineer. He has participated in the development of product safety standards for information technology equipment IEC 60950, the new hazard based standard IEC 62368 and on several other standards technical panels. He is a member of National Electrical Code Making Panel 12. If you or anyone you know would like to give a product safety technical presentation, please contact Tony Nikolassy by email at a.nikola...@yahoo.com. A technical presentation should be 45 to 60 minutes in duration and be related to product safety. Although the presentation may reference your company and it’s services, the presentation must not be simply company advertising. We would also appreciate any slides or handout materials be made available for posting on the NPSS web site. Releasing presentation materials for posting is desired but not a requirement to make a presentation. The 2012 NPSS meeting schedule is available on the NPSS website at http://www.nepss.net/calendar.html. Further information about the Northeast Product Safety Society and how to become a member is available at http://www.nepss.net. You can also contact one of the NPSS officers via links on the NPSS web site. Directions: From Route 495 North or South, take Exit 28 to Route 111 East Turn right onto Adams Place (approximately 500 feet from Route 495 North) The Holiday Inn is the last building on the left.

[PSES] Certification Labels in Software
Hello Everyone: Is there some sort of general understanding of being able to put certification labels in a product's GUI a la iPhone? These would be in addition to marks and their explanations in the equipment manual(s). I know that labels required for safety have to be placed on the outside of the equipment. So, what I'm discussing are things like C-Tick and A-Tick, WEEE, China RoHS, ANATEL, etc. Has there been pushback from any agencies? Thanks, John John R.
