UL 3111-1 vs. UL 3101-1

Folks- Can someone give the scope of UL 3111-1? Or tell me how is it's scope differs from UL 3101-1? I have a copy of UL 3101-1, and it appears that it is very similar to IEC 1010-1, but I don't have a copy of UL 3111-1 (yet!). I read a message in the IEEE-PSTC archive where someone said that

Re: Impedance Shielding Eff.

There is an ASTM (I do not recall the number) for just your purpose. The jig is an expanded piece of coax, with a slot into which a puck of the test material may be inserted. If the material is a perfect conductor, it shorts the input and you get no output. If the material is a perfect

Ken, a jig like you describe was made and marketed by Elgal in the USA. It was called a SET 19 I believe. Derek. --- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list. To cancel your subscription,

Antonio, When I was a little younger, we tested a bunch of panels to help determine the make up of an aircraft structure. Our panels were about 10 by 18. We did the testing by putting the panel in the shared wall between two shield rooms, creating a field in one, then measuring the field in

Annother EN61000-4-8 Issue

I believe that Clause 7.2 contains an error. Clause 6.2.1 requires the field variation be no more than +/- 3 dB over the volume of the EUT. For a 1 m square loop, the test volume is 0.6 m x 0.6 m x 0.5 m (h) with the loop centered on the test volume. Therefore, a vertically oriented loop would

The device will need CE, thus the typical route is a tech file and a DoC. Refer to the Medical Device Directive (MDD) or the In-Vitro directive. From the little info you provided I would guess the Medical Directive is the one. Reading the scope of both should assist you in selecting the

Re: [Fwd: [SI-LIST] : Copper balance]

Hi! Cortland: Thanks for your comments. In your experience, does the size/spacing of the copper dots or islands matter as long as their dimension is much smaller than the wavelength for the highest possible frequency on the card ? Any special considerations other than that ? Regards Perry

RE: Beta Shipments

Brent: So far as the US is concerned, it is generally OK in limited quantities. You will need to label them as not for sale and not FCC approved. DO NOT sell them before certification or DOC, or at least not without a conditional sales agreement. All the details are in the FCC rules (WORD file)

I appreciate the comments that I have received, but no one is answering my question, which is, can tall ( 0.5 m) equipment be tested using a single horizontal 1 m loop that is moved along the height of the equipment? Obviously, a larger loop is required for the vertical testing. Richard Woods

Re: [Fwd: [SI-LIST] : Copper balance]

Yes indeed. My preference is for thieving to be done with dots or islands small with respect to the shortest wavelength of concern. This is because thieving can be constructed so as to resonate and aggravate an EMI problem. Some years ago, at an employer far away (grin), we had obtained

Richard, our approach has been to size the loop to the EUT. We presently have 1 meter and 2 meter (square) loops that are multi-turn conductors inside 3/4-inch thickwall white PVC. Our 3 meter multi-turn loop uses external supports, and is designed with a multi-conductor plug and socket so that
