"made in xxxx" requirements?
This is not my usual area of interest, but a question came up about regulations for country of origin marking, either in the US or EU. Can anyone point me in the direction of an answer?

CE Marking a compnent transformer
To All, Any assistance is greatly appreciated. Our client would like to evaluate a component transformer for CE marking or to ship to an OEM for inclusion in a piece of "box making" equipment built in the EU. I believe the safety standard is EN 61558-1. Does anyone have a difference of opinion on this and are there any other requirements (EMC, other)?

Re: EMSCAN data
I'd be interested in seeing what you've got. Remember, not only the board can resonate, but structures on and in it, and at lower frequencies, too. Don't send the file to my Compuserve address, though; I can only see text here.

EU Electrical Codes
We need to embed secondary wiring (>50V) into a narrow trench cut into a concrete floor located at ground level. The installation has to be compliant with the electrical code used in the EU. It has been suggested that we use flexible conduit such as the one listed at the this link. http://www.courant-int.com/catalogue/items/icta3422.htm Is this material acceptable in this particular application? If not, what material must be used? Richard Woods Sensormatic Electronics Tyco International --- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.

Pusle generator
Hi all, I'm looking to rent a pulse generator to perform pulse testing in accordance with the 1 MHz waveshape in MIL-STD 461 E CS116. Can anyone suggest a source. Thanks, Derek N. Walton Owner, L. F. Research EMC Design and Test Facility 12790 Route 76, Poplar Grove, IL 61065 www.lfresearch.com
Re: the experts (was: RE: Multiple Product Variants under EN60439)
Well, for my two bits, I've always dealt with agencies as if they're from Missouri "The Show Me" state. And since specific applications can and do in many instances vary greatly, I have had some test engineers make some general statements but not many. They probably have had their fair share of people who are more unfamiliar than most about standards run off stating this or that as law when they really don't know what they're talking about. I find that true to some extent in any company where I've worked. And my knee jerk reaction is to ask to physically see whatever the issue is on something. It's just part of the job I guess.

the experts (was: RE: Multiple Product Variants under EN60439)
This reaches back a bit and I hope you'll forgive my tardy entrance. I come from a test house background and would like to shed some light on certain assertions made in this thread. Scott Douglas tells us, "In my years of being a compliance type, I have found many cases where I could not get an agency or test house to make a bold statement about this or that. Often one can accept that and understand why they will not commit. For one reason, they do not want to be the one sued by some disgruntled customer because something happened (or didn't happen). But just as often, I have found it extremely frustrating that I cannot get a straight answer from the same people." It's also important to keep in mind that anything said by the engineer might be contradicted, when presented to their reviewing engineer, leading to personal embarrassment. A bad decision could also lead to a precedent that is difficult to be rid of. Mulling things over is good for all concerned, especially the public's safety. I do agree, though, with Scott's advice to question anything that doesn't make sense. Insisting on clear engineering rationale is good practice and will even help the test house engineer maintain clarity. Sometimes the (unsatisfying) answer might only be "it's a compliance issue," implying a standards revision is called for. Chris Maxwell advises, "Personnel at a lab may deal with the same standard everyday. They should know the standard like the back of their hand." This is sometimes true and sometimes not true. In one department, I recall handling an average of 15-25 and as many as 40 projects at any given time, usually with little customer or technology overlap, often with only a little overlap in product standard. [In the case of industrial control equipment, the range covered products are so broad that it can be daunting to know even half of what an "expert" might need to know; a good understanding may be more difficult to muster (thank goodness for dash standards - a relatively recent innovation).] At any given time, for example: relays, branch circuit breakers, cartridge fuses, Class 2 transformers, unit substations, pool and spa equipment, panelboards, energy management equipment, printed wiring boards, general purpose transformers...the list goes on. It can be a juggling act to keep the requirements clearly in mind for any particular product and standard, especially in busy times. There are also relatively new employees that are still cutting their teeth on a standard, those that transfer between departments that handle different products and have to learn new standards, almost anything of the ilk. Nevertheless, there are some groups within these organizations that deal with relatively few standards and perhaps the back of the hand idea applies (for instance, ITE and telecom equipment, polymeric materials), but it depends sharply on the internal structure of the test house and how they run their businesses. The odds are great that we'll all act the teacher to test house engineers in our careers. Many serving on standards making panels on this forum fulfill this function regularly. Chris is right, though, that it can make a big difference if the test house engineer is familiar with a customers products and design philosophy. Regards, Peter L.
