Re: Korean Requirements
Bruce et al, The APEC MRA, of which Korea is a member, has matured to the point where test reports are being accepted from member countries given that certain criteria are met. Those criteria are basically test lab quality system oriented. We have been successful in gaining EMC approvals from other APEC member countries with test reports from labs in the US (we have not pursued Korea as yet). For those interested, go to APEC's web site for further details, member countries, etc.: http://www.apecsec.org.sg/ Please in mind that this MRA is still fairly new and alignment procedures are likely still being worked out by the member countries, although I suspect after about a year now, a lot of the dust should've settled by now. It is possible that some agencies affected by the APEC MRA may choose to fully ignore the MRA, may be unclear as to how to proceed, or my only partially accept the MRA. That is, of course, their priviledge. Anyone else benefitted by using the APEC MRA? Comments?

RE: Are NTCs Safe to Use in Electrical Equipment

RE: Are NTCs Safe to Use in Electrical Equipment
I really don't have a clear idea of whether or not your solution will work. Let us know. NTCs, as with most thermistors, get very hot when in their switched state. For the NTC, that's it's steady-state condition. I wouldn't put this in a junction box with other wiring, unless you're absolutely certain all the wiring can take the temperatures they'll encounter (for normal household wiring, likely not). Rather, for the sake of your experiment, put the NTC in a separate (probably should be metal) box that's in-line with the receptacle, with appropriate goesintas and goesouttas. Be certain to use your best safety engineer's hat for this activity. Regards, Peter L.

I have a circuit in my house that blows light bulbs far more often than any other. I can't determine any reason for this - the voltage seems normal and there aren't any transient-producers on that same circuit (that I'm aware of). Long life and rural-duty bulbs make little or no difference. Instead of figuring out the root cause, I'm considering resorting to trying to deal with the symptom (blown bulbs) by putting an NTC in series with the light fixture somewhere. My thinking is that the mechanism that blows an incandescent bulb filament is related to the high inrush current into the cold (and therefore low R) filament, and the physical and thermal stresses that that inrush causes. Any comments on how likely this is to help, and whether or not I can safely put an NTC in an junction box full of wires? I'd check the NTC's temperature under load (they get hot) and compare that the the temp. rating of the wires in the box. I'd also insulate the bare legs of the NTC and try to make sure it isn't touching anything else. Anyone familiar with the failure modes of these things?

RE: PDF file copy method
Barry, If the protections are set so that you can neither select text nor print, you are pretty much out of luck. If the problem is that the pdf file was created from a scanned document you may be able to print to a fax file (if you have a fax modem card and appropriate software. Many fax programs have OCR (Optical Character Recognition)capability. You can print to a stored fax file, and then open it as if it were a received fax, using the OCR input option. Some OCR programs are better than others at recovering text correctly. It's worth a try if you or a co-worker already have the software. Just a thought.
