Re: solutions for markings durability test
Brian: The poor man's answer is as follows: 1. Garage or car parts emporium (battery top up water) 2. Hardware/building supplies shop 3. Tricky. Not widely available, but often used in disc drive head cleaners. 4. Tobacconist (it's basically lighter fluid). If you order from a chemical supplier, you will need to know that Meths is a mixture of Methanol and Ethanol (20%/80% IIRC, but don't quote me on that) with trace additions of a colour and taste to make it undrinkable. See http://ptcl.chem.ox.ac.uk/MSDS/ME/methylated_spirit.html for details. IPA is these days formally known as 'Propan-2-ol' or 'Isopopanol'. Since Methanol is generally a pretty aggressive solvent (at least as far as inks and adhesives are concerned), I'd be surprised to find many common marking systems which will survive meths but are dissolved in IPA. A rich man, or one looking to cultivate relations with his accreditation body, would probably contact one of the major chemical lab supplies companies (e.g. Merck), who I am sure will be delighted to provide any and all of the above to any level of purity you require, for a handsome fee!

Re: Creepage on PCB Internal Layers
In a message dated 8/13/2002, you write: To me, it's sort of funny in that it just says that the Creepage and Clearance distances do not apply on inner layers of void free PCBs. That's nice; but I can't find where a distance is specified. I mean, I would think that there should be some minimum distance between an AC line and a 5V SELV line on an inner layer of the board Our layout guy has a military specification that specifies insulation for 300-500V circuits. It specifies .100 on external layers and .010 on internal layers...which would work out to a factor of 10 reduction between surface layers and inner layers Hi Chris: I work with EN 60950, not EN 61010-1, so my comments here are only general. In EN 60950 the creepage and clearance requirements can be eliminated for inner layers, but all other requirements for the relevant insulation still apply. For example, both supplementary insulation and reinforced insulation still require a minimum of 0.4 mm through solid insulation. Also, any relevant hipot tests for the insulation in question still apply. In general, a well constructed circuit board will have extraordinary insulation between traces on the same layer, due to the high dielectric strength of the prepreg and the bonding agents that are used. Even a separation .002 will, in theory, have a dielectric strength of more than 1000 volts. However, I prefer to be cautious here, in the event that a defect creates a small air gap in the isolation area. I would suggest using as large a gap as you can reasonably achieve, even if the regulations call out no minimum or a minimum of only 0.4 mm. The 0.8 mm target that you have nominated sounds OK to me, but if you can bump it up to 1.0 mm or more, that would be nice.

Laser Emissions Measurement
Consider a Class 1 Laser Product. Once the protective cover is removed for service, it is physically possible for the 12 mm probe to be inserted into the beam where Class 2 levels are present; therefore, human exposure of a finger is possible. However, it is not physically possible to directly view the beam nor is it possible to place the measurement instrument into the beam at the specified measurement distance of 100 mm. What are the measurement requirements in this case? Must I take the system apart such that the beam can be measured? If not and since Class 2 limits are based upon viewing considerations and not finger exposure, do I get off the hook for needing the Class 2 warning label on the protective cover?

RE: Creepage on PCB Internal Layers
Yes, Thanks Richard By the way...Rich Woods...Tektronics (Richard Payne's company) also makes fiber optic power meters. Sorry that I forgot to mention them in my reply earlier today. Yes, they're a competitor of ours; but their compliance guy is nice enough to answer my questions :-) ** Now back to the issue at hand. That's what I was looking for (the statement in paragraph 6.7 of EN 61010-1) The copy that I have has the amendments separate. I found it in Amendment 2 as you stated. To me, it's sort of funny in that it just says that the Creepage and Clearance distances do not apply on inner layers of void free PCBs. That's nice; but I can't find where a distance is specified. I mean, I would think that there should be some minimum distance between an AC line and a 5V SELV line on an inner layer of the board Our layout guy has a military specification that specifies insulation for 300-500V circuits. It specifies .100 on external layers and .010 on internal layers...which would work out to a factor of 10 reduction between surface layers and inner layers. Using that same reasoning, I was looking at a circuit that needs 8mm of creepage on a surface layer (.314). Would I be safe in allowing 0.8mm (0.0314) of distance on an inner layer? Anybody have any thoughts on this one.

Re: solutions for markings durability test
Hi Brian, Get distilled water at any grocery store. I'm not sure about the methylated spirit, but I was able to get hexane from VWR Scientific www.vwrsplcom . Please note that any reagent grade will satisfy, but the cheapest is the way to go. One liter will last a lifetime, about $15 usd. Please note that, to obtain this material you must offer the supplier your employer's Federal EPA number. Oddly enough, I was years ago directed by my field engineer at UL NBK, to use WD-40 to perform the permanency test. Later on somebody tightened the sphincter and would not accept my test data, so I was forced to purchase hexane and use it and water for all tests (60950). All results were the same.

For fiber optic measurements (I'm assuming that you are measuring in one of the standard communication bands, such as 850 nm, 1310nm, 1550nm, 1625nm), you may be able to use power meters from NetTest (the company I work for), Fotec, Exfo, Agilent, Corning, Wilcom, Acterna...take your pick.

Re: Need copies of specs addressing ISM bands in Europe
Hi Robert, You'll probably find CEPT recommendation 70-03 on short range devices useful - it lists the ISM bands (ref: page 34 under 'Frequency Issues'), national restrictions and applicable standards. There's a link to it on the right hand side of the ERO home page.

EMC-PSTC / TC-8 At The 2002 IEEE EMC Symposium
Greetings All, This e-mail contains important information about the upcoming IEEE EMC Symposium, TC-8, EMC-PSTC, PSTC and Product Safety events. First off the exciting news is that we (EMC-PSTC / PSC) will have a booth at the upcoming 2002 IEEE EMC Symposium. It will be booth 131 next to the NAVY booth. In the booth will be the presentation given to the IEEE TAB in February of this year by the PSTC, concerning the desire to create a IEEE Product Safety Society. We will have information about this list server and about Mindcruiser. By IEEE policy, we are to have someone in the booth at all times. So I would like to challenge all of you (especially the PSTC chapters) to spend a few minutes in the booth so that we meet the IEEE requirements. I have a second challenge for all of you and that is to promote this list server to others who work with product regulatory issues. This is for two reasons. 1. To make sure everyone there, leaves knowing about the emc-pstc 2. Make sure those who could not go, learn about the emc-pstc. For example all of you at one time or another talk to regulatory engineers at other companies. Make sure they know about this list server. If you know someone who's e-mail can not handle the e-mail that the list server sends out (yes I know of at least one) they can always use http://ieeepstc.mindcruiser.com. The schedule of the TC-8 Meeting, PSTC Meeting, formal dinner for our speakers, and workshop, are as follows: 1) IEEE EMCS TC-8: Thursday August 22, 2002. 7:30am - 8:30am. PSTC Meeting immediately following. 2) Formal dinner for the speakers: Thursday August 22, 2002. evening. (Details will be posted in the booth on Thursday.) 3) Workshop: Product Safety FR-AM-WS-13, Friday August 23, 2002. 8:30am - 12:30pm. Room 212AB.

Re: VDSL for Brazil GPS for U.S

I am not sure what the second dashed paragraph means. How can a manufacturer of dc powered equipment decide the test current and the time? There is a similar requirement in the IEC 60 950 standard where the test current is twice the raing of the circuit for 2 minutes. However, the way this standard is written, seems to indicate that the dc powered equipment manufacturer can decide on the test duration ONLY of the test which is perfoprmed always at twice the current rating of the circuit. Any input to clarify the intent of the requirement would be greatly appreciated. This e-mail message may contain privileged or confidential information.
