Hi Pat Greg Gogates used to moderate a really good one, but he had to discontinue it. I think he still keeps the archives at www.fasor.com. Some good information on the site as I recall. There are some good message boards and contacts at http://elsmar.com/index.html, which is more of a resource

Hi all, I've been asked to help with the ISO 17025 approval of our safety laboratory. Specifically, to resolve issues of measurement uncertainty statements. Do any of you know of active web forums or listservers where these issues are discussed? Thanks, Pat Lawler EMC Engineer SL Power

RE: 60950 question

I can see one reason for a capacitance limit AND a current limit. Consider two sets of terminals with identical peak current specifications. However, one set of terminals has internal capacitance such that it will remain charged and capable of that peak current much longer after the product has

That is my take on it, why impose a capacitance limit at all if you already limit the current. But I think perhaps I'm missing the intent of the capacitance limit. In my wishes, and I do mean wishes, I could fail the 7uA limit, and meet the capacitance and thus be a limited current circuit.

All I have a separate question on the subject. We are supplying UK cords with 3A, 5A, or 13A fuses. The EUT side plug is rated 2.5A. The wire gauge is suitable for the respective fuse. The EUT uses only about 0.5A. Does it matter whether we use a 3A fused cord vs. a 13A fused cord? Asim

All - I've been following this discussion and, honestly, I don't see where the problem lies. §2.4.2 is pretty clear, in the context of the standard. Each paragraph stands alone (none are dotted or dashed). In the overall structure of §2.4.2, neither OR nor AND strictly applies: the conditions

Hi First part of 2.4.2 talks about frequency (over OR under 1 kHz) next part talks about voltage (over OR under 450 Vac) so it must be an AND between those two requirements (current limit AND Capacitance). This is how CSA told me about the requirements 8 yeasr ago. Best regards, Kim Boll Jensen
