Re: [PSES] EU wiring code low voltage / medium voltage transition
See appendix A - and read the note which says There is no International Electrotechnical Vocabulary (IEV).. http://www.hse.gov.uk/fod/infodocs/483_27.pdf Low voltage normally exceeding 50V ac or 120V dc but not exceeding 1000V ac or 1500V dc between conductors, or 600V ac or 900V dc between conductors and earth. High voltage normally exceeding 1000V ac or 1500V dc between conductors, or 600V ac or 900V dc between conductors and earth. Note Some companies and persons use the term medium voltage to describe distribution voltages in range 3.3 kV to 72.5 kV to distinguish these from the higher values of voltage associated with transmission systems. There is no International Electrotechnical Vocabulary (IEV) meaning which specifies values; all that is stated is that the upper value lies between 30 kV and 100 kV. The term has not been used in the UK to prevent confusion with the widely understood use of the term for 415 V 3 phase systems. -Original Message- From: Peter Tarver [mailto:ptar...@ieee.org] Sent: 22 February 2012 17:29 To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: [PSES] EU wiring code low voltage / medium voltage transition Good morning.

A business should be cognizant of it’s legal obligation regarding the disposal of all its waste so yes.

RE: Revision of the WEEE and RoHS directives
Yes I understand that, it was more the fact that some “consultants” are allegedly suggesting product manufacturers (note I don’t say downstream users (DSU)) need to analyse the chemical content of their products down to the last molecule e.g. document the complete chemical content of say a capacitor (and every other part of the product). Whilst the regulation does place some obligations on DSU’s this is not one of them. Regulation 1907/2006 Art 3 Cl 13 says: downstream user: means any natural or legal person established within the Community, other than the manufacturer or the importer, who uses a substance, either on its own or in a preparation, in the course of his industrial or professional activities. A distributor or a consumer is not a downstream user. A re-importer exempted pursuant to Article 2 (7)(c) shall be regarded as a downstream user; ECHA DSU guidance is here: http://echa.europa.eu/doc/reach/080417%20ECHA_08_GF_02-EN_Downstream_User.pdf So, as a product manufacturer you may be a DSU if you use a substance in your product, let’s say penetrating oil. If you use the oil in line with the oil mfrs guidance you have no obligation, if you however use it in a way not prescribed then you do have an obligation. If on the other hand you are just using resistors and capacitors you have no obligation as a user to analyse them. You may for business continuity want to ask the question back up the chain as to whether the resistor and capacitor might be discontinued due to REACH but that is all. A capacitor or resistor is an “article” and the Cl 56 of the Regulation says (part of relevance here is in bold between ): Part of the responsibility of manufacturers or importers for the management of the risks of substances is the communication of information on these substances to other professionals such as downstream users or distributors. In addition, producers or importers of articles should supply information on the safe use of articles to industrial and professional users, and consumers on request. This important responsibility should also apply throughout the supply chain to enable all actors to meet their responsibility in relation to management of risks arising from the use of substances.

For example, a small aerosol can of specialized oil for a machine might be within scope of the EU Narcotics Precursor Regulation, the REACH Regulation, the Dangerous Preparations Directive, the Aerosol Dispensers Directive and the Prepackaged Products directive, but the laws do not always cross reference each other (though there is some). In this same way, EEE within scope of RoHS could easily contain materials relevant to the restrictions of REACH (Annex XVII) or the Candidate List materials of REACH. It is nice to see the RoHS directive explicitly mention REACH (see the following) and to say it applies even though RoHS might also. REACH, of course, is the acronym for Regulation 1907/2006. Reference to REACH - This Directive shall apply without prejudice to requirements of Community legislation on safety and health, on chemicals, in particular Regulation (EC) 1907/2006 as well as of specific Community waste management legislation.

RE: Revision of the WEEE and RoHS directives
My reply was in respect of the proposed amendments. If the original equipment
supplied is not in scope then spares do not have to be in scope, period. If
someone deems to take the supply out the printer and use it for another
purpose then that is their “folly”. Think what would happen if you applied
your rationale; every nut bolt in the machine could be said to be useable
outside the original equipment.
What you really need to consider is what constitutes large scale stationary
industrial tools as there are printers and printers... if the
installation is a purpose built print mill then it would almost certainly
qualify but if it’s just a large floor standing print press then almost
certainly not.
The UK enforcer FAQ defines LSSIT as:
http://www.rohs.gov.uk/FAQs.aspx#11
* Consist of a combination of equipment, systems, products and/or
components (therefore not a singe discrete tool such as a small or medium
scale lathe, milling machine or pillar drill)
* Be a tool and not be covered under any other category
* Be required to be fixed to operate safely or within specification
* Be of ‘large-scale’
* Require professional installation
* Only be used in an industrial environment
* Be built to perform a specific task

Subject: RE: Revision of the WEEE and RoHS directives
Chris,
Is that your read of the current RoHS or the revision proposal? My question is
related to the revision proposal. This is what I see
Original RoHS said
This Directive does not apply to: spare parts for the repair, or to the reuse,
of electrical and electronic equipment put on the market before 1 July 2006.
[Art 2.3]
Proposed Change says
This Directive does not apply to:
(a) equipment which is necessary for the protection of the essential interests
of the security of Member States, including arms, munitions and war material
intended for specifically military purposes ;
(b) equipment which is specifically designed as part of another type of
equipment that does not fall within the scope of this Directive and can
fulfill its function only if it is part of that equipment;
(c) equipment which is not intended to be placed on the market as a single
functional or commercial unit.
[Art 2.3]
[James, Chris] these merely clarify already given or understood interpretation
of the existing directive.
So getting exemption here depends on
[James, Chris] you are not “getting” an exemption, it is already given.
* clearly understanding can fulfill its function only if is part of that
equipment - It seems a PSU can still fulfill its function of providing power,
in or out of a printing press.
[James, Chris] as above, so can a screw of nut but if the product is not in
scope then neither are it components.
OR
* demonstrating that the PSU is not being placed on the market as a single
functional or commercial unit - but what exactly is meant by single
functional unit or commercial unit? No defs. are provided.
[James, Chris] agreeably this is vague, but again you are looking at the scope
which applies to the finished product not the individual components. Is the
finished product in or out of scope, I thought you had decided it is out as
it’s large scale stationary industrial tools.
Further, later in the proposal it is stated
Member States shall ensure that EEE, including spare parts for its repair or
its reuse placed on the market does not contain the substances listed in Annex
IV {the big 6}. [Art 4.1]
With some exceptions
4. Paragraph 1 shall not apply to spare parts for the repair or to the reuse
of the following:
(a) EEE placed on the market before 1 July 2006.
(b) Medical devices placed on the market before 1st January 2014.
(c) In vitro diagnostic medical devices placed on the market before 1st
January 2016.
(d) Monitoring and control instruments placed on the market before 1st January
2014.
(e) Industrial monitoring and control instruments placed on the market before
1st January 2017.
(f) EEE which benefited from an exemption and was placed on the market before
that exemption expired.
So the PSU which might be considered a monitoring and control instrument in
its own right, is a spare part for the printing press (a electrical tool) and
so may only benefit from (a), but if the particular printing press being
repaired was placed on the market this year, there is no available exemption.
[James, Chris] yes there is as you said it’s LSSIT which Annex I cl 6
excludes from scope.
Regards,
Lauren

Subject: Outlet Connector 250VAC 2.5 amps
I’m looking for an AC Outlet connector similar to the IEC 60320 C6 or C8,
but an outlet instead of an inlet. I need to run AC power out of my product
to a small external device which mounts on the side (lab equipment) and will
only draw less than 2 amps at 230 Vrms. I do not want to use the large
Appliance outlet connector. Any suggestions? I checked Interpower and Power
Dynamics but no luck. Wouldn’t such an application require the ground pin
to mate first and break last? If so then I would be able to use just any
connector.

RE: Wall warts for UK use
The 13A UK wall socket is always earth pin uppermost as I’m sure you know when fitted to a wall – extension leads laying on the floor and floor boxes are another matter. The intent with the warts with cable coming out the top is that the cable is going to run upwards to a desktop/work surface. So it’s a functionality issue and one that in the majority of applications I find appropriate. What does it matter the label is upside down – how often do you look at the label?? The only issue I have is when a wart has to go into a recessed floor box when there is often insufficient space to accommodate the cable strain relief exiting the top.

The cable entry is then often at the top causing the wall wart to lean out from the socket and any logo and labelling is also up the wrong way. Not just small manufacturers either, but the big guys too (I have Motorola phones, Netgear routers, all upside down!) Don't the manufacturers check? Is there a widely circulated representation of the UK sockets that has the diagram inverted? A minor thing I know, but it irks!!

For example, IEC 61010-1 Table 1 only indicates 3 symbols that have the triangle enclosing the symbol. While, IEC 60417 does not indicate this. One that seems to be missing from IEC 61010-1 is the exclamation point in triangle. I've reviewed IEC 60204-1, EN50178, EN60950 as well and I find varying requirements, some more than others. SEMI S2 seems to indicate that nearly every symbol belongs in a triangle. I'm guessing that if it is an informational symbol, you do not use the triangle, but countering this, I have seen the hearing protection warning in a circle without the triangle. Does anyone know of a reliable rule-of-thumb for when to use a triangle on an IEC/ISO international warning symbol? By the way, here's a trivia question to which I do know the answer: On the circle-bar label warning, which angle does the slash take, from 10:00 to 4:00 or from 2:00 to 8:00 on the clock face? thanks, -doug Douglas E.

In our product we shipped them with a spare fuse in order to benefit the customer in case they needed it. The intent was that in case they did blow the fuse that they would have an identical and properly rated replacement fuse available to them.

RE: EMC-related safety issues
Sorry disagree about turn and brake lights not being in the same class. Their very failure is often the reason for very serious accidents. I have long wished that all car manufacturers had to by law fit bulb failure warning devices to cars (but what happens when that fails). In the UK it is an offence to drive a vehicle with defective lights, (although many do). It is the driver's (not owner's) obligation to be satisfied the vehicle they are driving is fit to be on the road irespective of whether it passed it's MOT the previous day. The UK mandatory annual vehicle inspection (MOT) for vehicles over 3 years old, covers seat belts, brake efficiency on a rolling road, mirrors, windshield cracks (a 20mm, 3/4inch crack in the wrong place will fail a vehicle), tyres, wheel bearings, gaiters, steering components, structural body condition, lights, smog emissions, etcI don't believe airbags are tested but guess it will come, along with the inevitable hike in price. I'm surprised the US does not have a similar Federal requirement - with all the vehicles this is a cash cow waiting to be milked.

RE: EMC-related safety issues
Ken, I don't think anyone could disagree with your sentiments. The problem is attributing the level of liability between user and manufacturer. Car manufacturers sleep at night yet their products kill thousands each year, they design them to high standards yet by their use they still kill and maim. Do we hold them liable, no, in 99.9% of cases we don't. You slip down the stairs and break your leg, do you sue: * the caveman who invented the staircase? * your shoe manufacturer for using a shoe sole incompatible with the stair carpet? * the stair carpet manufacturer for using material incompatible with the shoe sole material? * the distiller for not putting a warning on the bottle of whisky you just drank It's reasonable responsibility/diligence that needs defining, not spurious emissions!! In addition the legal fraternity should have some standards imposed upon them to put an end to pure gold digging through litigation that seems to just escalate and to which we thus have to pander.

Should we as Professional Safety Engineers and Product designers consider the safety implications of EMC emissions ? The answer is a definite Yes. We have a clear duty of care and responsibility to consider all implications of our products being used in there intended application. Even if the consideration on EMC emissions and safety is Do not be silly. We still have to at least consider it. It has been stated that CISPR22 and CFR Title 47 Part 15b is only concerned with interfering with radio transmissions. This is true and why the enforcement falls under the Federal Communications Commission. But not all products fall under this remit and could quite happily be emitting large EM fields and comply with all current US legislation. Take for example the line surge equipment you use to test immunity to EN61000-4-5, exempt from the Part 15B under section 15.29 as A digital device used exclusively as industrial, commercial, or medical test equipment. And clearly not medical equipment. Yet when operated can produce a magnetic field that will interfere with the operation of old style pacemakers. Should you consider this when addressing the safe design of the product, or blindly state you meet all applicable EMC regulations for this product. With my unit the manufacturers have considered this and clearly state in the user manual that people with pacemakers should not operate or be be near the equipment when it is use. Two lines in the manual is not very big much against the risk the of killing someone. In Europe for CE we have no choice. The LVD state quite clearly that testing to a standard alone is insufficient to demonstrate compliance. You to consider foreseeable use and misuse, and you have to perform a risk assessment on your equipment. Taking it down to the standard level IEC60950 3rd Edition, section 0.2.7 states you must consider the effect of rf radiation on service and user personnel. Another example, you build a IPC cabinet for to be built into a production line, again exempt from CISPR 22, yet when it it running, causes interference on the control circuitry of a nearby Robotic arm. In the US immunity testing is not required, so who is liable. A susceptible Arm or noisy IPC cabinet. Being that every was fine until the cabinet was installed, you can see the blame would be pointed. Simply put, if EMC emissions from one of your products caused someone's death, because you did not consider it important. Could you sleep at night ?

Replacing this driver solved my problem. It was diagnosed by: 1. Was the problem due to conductive or radiated or both? By using the DC lead, made a small loop, as my noise source with EFT test running, I noticed the problem occurring near the display circuitry. The fault was actually a Display lock whereas I thought it was a keyboard lock (same symptons). I then attached my large ferrite core to the DC cable, several turns, and repeated the test. No problems. I assumed from this that radiated was the problem. 2. What was actually picking up the noise and was the fault the display driver? I assumed the cable connected to my display was picking up this noise and conductively passing it on to the display driver. I could not bypass the problem using caps, functionality started to play up a bit depending on my value of capacitor. It was at this time I noticed that we were using an unfamiliar driver manufacturer!

(1) If 10 log (P1/P2) = 10 log (V1^2/V2^2) = 10 log (V1/V2)^2 = 20 log (V1/V2), Then does it follow that, dB = 10 log (aV2^2/V2^2) = 10 log (aV2/V2)^2 = 20 log (a) ? Eq.

The definitions may be conditioned by what the FCC is looking for. And in general, I have always tested my understandings for a sanity check, not as a proof. So, going back to the origins of the question, in some sections the FCC refers to an averaging detector, and a preference to use duty cycle with peak detection to provide the averaging detector reading. The FCC commented that they preferred math over averaging detectors due to linearity issues (per comments on a submission). So let's test the understanding: Given a 100uV signal measured by the peak detector in my spectrum analyzer. Given a 15 % duty cycle. The FCC would call this a signal equivalent to an averaging detector output of 15uV, 100 x .15 = 15 uV. If I wanted to simplify the handling of factors, I would apply the formula 10 log (P1/P2) or 10 log (V1^2/V2^2) = 10 log (V1/V2)^2 = 2*10 log (V1/V2) or in general, 20 log (V). The signal converted to dB would be 20 log (15) or 23.5dB If I want to simplify the handling of factors, I would apply the formula to the given value, 20 log (100) or 40 dB. If I apply the test to Ken's formula 10 log (a) = 10 log (.15) we have -8.2dB. As we are multiplying in linear terms, that means we are adding in log terms. 40 + (-8.2) = 31.8 dB If we apply the formula 20 log (.15) we have -16.5 dB. 40 + (-16.5) = 23.5 dB, which compares to 23.5 dB above. There is a piece missing somewhere as demonstrated when a test is applied.

RE: Compliance Documentation
Chris, Acrobat is very good. In addition to virtues already mentioned by others you can electronically sign PDF documents. Acrobat also has a Paper Capture function which runs an OCR on scanned text, converting it back into text which you can cut'n'paste back to other documents in Word etc. The OCR works well but the documents must be scanned at a certain DPI. It also requires you proof read documents carefully, even if you paste the text back into an application where you can use spell check. I once sent a scanned report out which I'd OCR'd so I could reformat in a document and spell checked it but where the word burn was now bum - and of course spell check don't catch those!! There are also plenty of bureaus who will do bulk scanning of any documents from A5 to A0 size. Some also offer cataloguing services. In the UK I have got work done at about £0.05 per A4 sheet for bulk scanning on an auto feed scanner, rising to £1.50 for A0 drawings done on a flatbed. Doing the scanning yourself is tedious unless you can buy a commercial type scanner (See Canon/Agfa etc. websites). Office/Home user type scanners are pretty slow and only go to A4 size documents. Chris -Original Message- From: Chris Maxwell [mailto:chris.maxw...@gnnettest.com] Sent: 16 February 2001 16:58 To: 'EMC-PSTC Internet Forum' Subject: Compliance Documentation Hi all, I do have a question, but the setup is sort of fun, so here goes: Well, I'm at that point. A few years ago, when the EMC Directive was first effective, we had a couple of products that we put through testing. We started keeping Compliance Folders which consisted of a cover report generated with MS Word combined with our in-house test reports and third party test reports held together with a big rubber band. This was fun for a couple of products. It was also fun when our company could remember what we called ourselves and what our product names/models were. Well, business is good...too good. The corporate captains have been buying other companies, OEMing products from other people, OEMing products to other people, changing the corporate name, changing the corporate logo, changing product model numbers ... (buying 25,000 coffee stirrers with our logo on them, we used about 20 before they changed the logo. Anybody what a now obsolete GN Nettest coffee stirrer?) Now I have about 20 large folders with anywhere from 100 to 600 pages each. Every time we go through these excercises, I spend hours sniffing toner at the copier (may explain some of my personality) putting different headers and revision numbers on these documents. I then go through 1000's of sheets of paper to run off copies for our representatives and then 100's of dollars in shipping costs to get these 10 pound paper packages to the four corners of the Earth. This is on top of the revisions that we normally incorporate for product re-tests, re-designs ... My question is, is there a better way? I have considered buying Adobe Acrobat and then converting all of my Word Documents to Adobe documents. Then I could scan in the attachments. All of this digital information, I could then store on a CD ROM drive with a main directory for my cover report and sub-directories for all of the various 3rd party reports, CDRH filings ... We could then offer our Compliance information via pdf files on the web. Is anyone doing this? Do you have any recommendations for what software to use? What scanners work best? What scanner resolution will duplicate test reports without losing precious information? Better yet. Does anybody know of a service where you can send 1000's of pages of info to them for them to scan and convert to pdf files. This would prove valuable during the initial conversion. Has anybody tried this and been sorry they did? I'm ready to go digital. My goal is to incorporate word processed reports, third party test lab paper copies, third party test lab pictures, hand written data ... into a coherent package for storage and revision. I assume that many of you fight this same battle. Any hints or pitfall warnings would be greatly appreciated.

Correct, leds are covered. Typically it will be ultrabright leds used in daylight displays and custom arrays of ultrabright led dies that will fall into the scope of IEC825. We use such a device in a film reader. If you believe you are using a led which is bright enough to make you look away or not look directly at it in the first place, especially at close ( 1m say) range, then it's best to get it tested.

Kathy, I am no expert on IEC 60825, but may help a little. The standard is intended to prevent human exposure to light energy within specified wavelengths. It initially focused only on laser safety, because lasers represent a beam of focused energy, i.e. more uW per area. An LED is not a laser, but merely a light source. When this light is collimated and concentrated into a single beam, then it is a laser. LEDs were added to the scope of IEC 60825 to ensure that the output of any LEDs (laser or not) would be within acceptable exposure limits. In general, common LEDs used for operator panel indicators distribute their light energy over a roughly hemi-spherical surface, although not equally. In most cases, there is insufficient energy in any vector to cause an exposure problem.

RE: Test voltage for products to the U.K.
Equipment must be marked to include 230Vac in the supply range. For a wide input range PSU it is permissable to put say 90-240Vac as 230Vac falls within this range. For selectable ranges then 230Vac must appear as one of those ranges although it is acceptable to say 100/120/220/230-240. Section 4 of EN60065 says equipment must be tested at .9 and 1.06 times the RATED SUPPLY VOLTAGE, where RATED SUPPLY VOLTAGE is defined as the voltage for which the manufacturer has designed the apparatus. Thus if you spec/mark it to work at 240Vac then it will be tested at 254.4 and if you spec/mark it to work at 230Vac then I read it as only being tested at 243.8Vac. However the test house (part of a world wide group) we use say they use 230 +10% or 240 +6% which is approximately the same thing.

RE: Global Engineering Change Process
We at Dolby have been using Agile for the past 4 years and overall have been very pleased with it. We have manufacturing sites in the UK and California and a separate Engineering site in Califorinia. We work it real-time across a WAN and it has been immensely useful for the control and dissemination of Engineering and Manufacturing data at all levels of product manufacture and development. Our previous change control system was basically a manual system aided by email, fax and WAN access to (CAD) data on remote servers. Agile has certainly pulled it all together. The only real downsides we have found are: there are upgrades from Agile every six months which require full re-installs for all users. If the main server gets upgraded then all users companywide have to upgrade. access on the far end of a WAN away from the main Agile server is noticeably slower than for users local to the server and can be frustrating if you use the system a lot. However this is really down to the bandwidth of the link. Chris James Engineering Services Manager Dolby Labs Inc.

RE: EMC Directive revisions
Hoping this reaches the right eyes. Our comments on the document: 1. In many places, the English is not idiomatic and lays stress inappropriately, often by incorrect use of the negative or of does. For instance this phenomenon needs not to be considered means it is compulsory not to consider it! Sometimes this doesn't matter; sometimes it would have legal significance. If the English text is to carry legal weight, it should be edited by a native English speaker to ensure that it does not convey the wrong meaning; the same applies of course to all the other languages. 2. In annex II section C.1 concerning documentation accompanying a product, there is the requirement that documents (presumably all of them, including instruction manuals, declarations of conformity etc. etc.) have to be available in one of the official languages of the member state where the apparatus is to be taken into service ... I understand the desirability of this for consumer goods, where it is generally followed today, but for professional equipment I think it is unnecessarily onerous. A manufacturer such as Dolby might sell only one or two samples per year of an apparatus into say Finland or Portugal, and to have to translate and print multipage documents into those languages would be uneconomic. 3. Article 5 contains a section that states: Member States shall not impede for reasons relating to electromagnetic compatibility the placing on the market and/or the taking into service for its intended use of equipment conforming to this directive. As you are well aware, states and smaller administrative areas such as cities are currently impeding installation of equipment that conforms to the present Emc and low voltage directives, despite CE marking and accompanying declarations of conformity . I suggest that this clause should be strengthened to make clear that it applies not only to national governments but to others as well.

Part 3 Body Strength and Stamina, and specifically to the following paragraphs: DEF 00-25 (Part 3)/2 Para 10.1.1 10.1.2, states the person-carry guidelines to be: Men 20kg, Women 13kg. However, DEF 00-25(Part 3)/2 Table 10 97th percentile two-handed lift guidelines from just below waist height are: Men 42kg, Women 18kg. From our recent experience I would recommend that you should generally NOT mark items as 2 man lift etc., as the ability of persons to lift and carry do vary considerably as demonstrated in this document. Again, from experience, I would use such markings only if the item is very heavy indeed or is of such a shape as to make it dangerous for less than a given number to try to lift or carry it. However, what I would do is to annotate the installation and use instructions with a recommendation that personnel handling such equipment shall required to undergo formal training in the manual handling of equipment in general. I would also ensure that these instructions contain warnings and specific weight data for each piece of affected equipment.

RE: Stroboscopic light sources
Try searching on: Photosensitive epilepsy - refers to seizures triggered by flashing lights One book on the subject: Photosensitive Epilepsy Harding, Graham F.A. and Jeavons, Peter M. (Mac Keith Press) Abstract: Photosensitive epilepsy is a relatively rare condition in which convulsions are precipitated by visual stimuli. The authors have spent almost thirty years studying this condition and have assembled the largest group of patients ever studied by one center. This book reviews the earlier studies, reviews all the literature on this condition in humans, and details the many studies that have since been carried out, including studies on drug therapy, the long-term prognosis for the condition, pattern sensitivity, video game epilepsy, and convulsions precipitated by other video material. In addition there is advice on procedures to reduce the risk of stimulation from television as well as such factors as the genetics of photosensitivity. -Original Message- From: Nick Williams [mailto:n...@conformance.co.uk] Sent: Wednesday, March 29, 2000 4:11 PM To: emc-p...@majordomo.ieee.org Subject: Stroboscopic light sources Does anyone know of any good resources or actual requirements for the safe use of stroboscopic light sources?

RE: IEC 825 and Light Emitting diodes.
We have a product using a focused high power led array which we had tested and was determined as Class 2 and so mark the equipment such. There are a number of high power leds on the market for use as indicators in areas of high ambient light, i.e. public display boards. When viewed from close range such leds are extremely bright. It is leds such of this type that I would consider prudent on having tested.

Hi group, When evaluating IEC 825-1 for fiber optic LAN transceivers I came across requirements for LED's. I have known that the EU had some requirements for LED emission. Being on the US side of the pond I have not seen how it is applied. Are manufactures doing fault testing on LED to ensure the class 1 levels are maintained? Are manufacturers labeling products with LED's (this covers just about every electronic product I know of) with the CLASS 1 LED PRODUCT as required in 5.12 of IEC 825?

Chris -Original Message- From: Nick Williams [mailto:n...@conformance.co.uk] Sent: Friday, September 10, 1999 9:40 AM To: emc-p...@majordomo.ieee.org Subject: BSI 'on-line' service I'm posting this message since it may save a few other people from wasting some time like I have done in the last few days. In the latest issue of Business Standards, the magazine which BSI send round to all subscribers, there is a splash article about BSI's new 'online' service which will allow the downloading of 'thousands' of BS standards in PDF format from their web site. As usual for articles in Business Standards, the magazine contains a great deal of waft but damn all useful information about the service (such as what's available and how much it will cost). Great, I thought, at last BSI has got their act together and I can download the standards I need when I need them. So long as there's no premium to pay over the paper copy cost, that would be really good, thinks I. Turns out not to be the case. Actually what is being provided is on-line access to the Technical Indexes CD-ROM service. To gain access to standards on line, you have to subscribe to one of the modules of standards (for a price of several thousand pounds) and you can then download only standards from that module. Also, if my experience is anything to go by, either the standards they've processed so far are really obscure, or the search engine used to locate standards doesn't work. I tried entering 'environmental' and 'machinery' and no hits came up in either case. So, for those of us who (a) don't have two or three thousand pounds to spend on a subscription and/or (b) are never quite sure which standards might be required, the services is useless, and it's back to the telephone for ordering paper copies.

RE: Doubt on household equipment interference
In the UK and I believe Europe I would not expect to see 3 phase brought into a household environment as this would expose the customer to line voltages (root 3 x phase voltage [line-to-neutral]). Even in office locations the power outlets are kept to a single phase per floor to prevent an inadvertent connection between two phases. Even if your scenario existed it would depend how the neutral was wired to each outlet; if it was a common neutral ring then the chance of problems would be greater than if each phase was fed with its own neutral return from a star point.

Subject: SCART specification question
I've been asked to look at a gadget which is intended for connection to
the
SCART port on a TV or VCR. The gadget in question is powered via a
plug-top
transformer, which we can specify to be SELV output.
My question relates to the specification of the SCART port which is, I
guess, a standard configuration (although a key-word search on SCART in
the
BS catalogue throws up no references, I notice...)
Is it, or is it not, safe to assume that connections made to the SCART
interface are SELV? In other words, even if we ensure that all parts of
our
product powered at SELV, do we have to treat those parts connected to
the
SCART interface as potentially live, or can we assume that they too will
be
SELV?
Any ideas (including a reference to the basic SCART specification) would
be
helpful.
Regards
Nick.

You wrote: Can somebody tell me what does TEMPEST stand for ? I don't think that the letters stand for anything, rather it is a (British?) set of performance specs, standards, requirements essentially aimed at maintaing confidential communications. E.g. a Tempest monitor will not bleed video or z modulation signals that may be picked up by a sensitive receiver nearby. I've seen a demosnstration at an exhibition where the exhibitor of an 'Intrusive Monitor System' was able to dut up a screen display of all the screens around him at will, just by homing in on their timebases and video signals with a highly directional antenna. TEMPEST, seeks to eliminate this leak of 'intellligence'. It's not only monitors, but data comms, RF, printers, anthing which could radiate, or conduct, data to an interested and well equipped third party. At least I think that's what it is. :-) Chris Dupres Surrey UK. - This message is coming from the emc-pstc discussion list.

RE: TEMPEST - the whole nine yards
A review of TEMPEST Legal Issues Notice: I recieved this document a bit chopped up, while it is complete thetext is mismatched with the references, and several references appear to be missing. In the novel 1984, George Orwell foretold a future where individuals had no expectation of privacy because the state monopolized the technology of spying. The government watched the actions of its subjects from birth to death. No one could protect himself because surveillance and counter- surveillance technology was controlled by the government. This note explores the legal status of a surveillance technology ruefully known as TEMPEST[2]. Using TEMPEST technology the information in any digital device may be intercepted and reconstructed into useful intelligence without the operative ever having to come near his target. The technology is especially useful in the interception of information stored in digital computers or displayed on computer terminals. The use of TEMPEST is not illegal under the laws of the United States[3], or England. Canada has specific laws criminalizing TEMPEST eavesdropping but the laws do more to hinder surveillance countermeasures than to prevent TEMPEST surveillance. In the United States it is illegal for an individual to take effective counter-measures against TEMPEST surveillance. This leads to the conundrum that it is legal for individuals and the government to invade the privacy of others but illegal for individuals to take steps to protect their privacy. I. INTELLIGENCE GATHERING Spying is divided by professionals into two main types: human intelligence gathering (HUMINT) and electronic intelligence gathering (ELINT). As the names imply, HUMINT relies on human operatives, and ELINT relies on technological operatives. In the past HUMINT was the sole method for collecting intelligence.[4] The HUMINT operative would steal important papers, observe troop and weapon movements[5], lure people into his confidences to extract secrets, and stand under the eavesdrip[6] of houses, eavesdropping on the occupants. As technology has progressed, tasks that once could only be performed by humans have been taken over by machines. So it has been with spying. Modern satellite technology allows troop and weapons movements to be observed with greater precision and from greater distances than a human spy could ever hope to accomplish. The theft of documents and eavesdropping on conversations may now be performed electronically. This means greater safety for the human operative, whose only involvement may be the placing of the initial ELINT devices. This has led to the ascendancy of ELINT over HUMINT because the placement and monitoring of ELINT devices may be performed by a technician who has no training in the art of spying. The gathered intelligence may be processed by an intelligence expert, perhaps thousands of miles away, with no need of field experience. ELINT has a number of other advantages over HUMINT. If a spy is caught his existence could embarrass his employing state and he could be forced into giving up the identities of his compatriots or other important information. By its very nature, a discovered ELINT device (bug) cannot give up any information; and the ubiquitous nature of bugs provides the principle state with the ability to plausibly deny ownership or involvement. ELINT devices fall into two broad categories: trespassatory and non-trespassatory. Trespassatory bugs require some type of trespass in order for them to function. A transmitter might require the physical invasion of the target premises for placement, or a microphone might be surreptitiously attached to the outside of a window. A telephone transmitter can be placed anywhere on the phone line, including at the central switch. The trespass comes either when it is physically attached to the phone line, or if it is inductive, when placed in close proximity to the phone line. Even microwave bugs require the placement of the resonator cone within the target premises.[7] Non-trespassatory ELINT devices work by receiving electromagnetic radiation (EMR) as it radiates through the ether, and do not require the placement of bugs. Methods include intercepting[8] information transmitted by satellite, microwave, and radio, including mobile and cellular phone transmissions. This information was purposely transmitted with the intent that some intended person or persons would receive it. Non-trespassatory ELINT also includes the interception of information that was never intended to be transmitted. All electronic devices emit electromagnetic radiation. Some of the radiation, as with radio waves, is intended to transmit information. Much of this radiation is not intended to transmit information and is merely incidental to whatever work the target device is performing.[9] This information can be
RE: LFM test rig
If you just need the flow over the unit then get a good length of tube (air conditioning duct, round / square or rect in section) large enough to take your unit with space around it, a variable speed desk fan and a hot wire or mechanical (vaned) anemometer* (air velocity measuring instrument). Place unit in middle of tube, the fan at one end and if a hot wire anemometer then place thru a drilled hole in the duct positioned well down stream of unit, if a vaned type then probably just have to place at end of duct (but a little way in). The duct will need to be fairly long (wrt the UUT) to reduce turbulence effects. Knowing the air velocity, and cross sectional area of the duct you can calculate the volume flow rate. If you stick thermocouples in the duct before and after the UUT you could get a rough calculation of dissipation too, (depending on the flow rates involved). *Anemometers: http://rswww.com 188-1125 Pitot tube,Digitron,AF200,anemometer 188-1119 Anemometer,kit,Digitron,AF200 or hire one or borrow one from your local friendly heating and ventilation/ process extract company.

Subject: A label for a Tipping Hazard
Happy Holidays,
We're working on a rather large project that has pull out drawers for
servicing some of the sub assemblies. The drawers are heavy, but low
enough
that the unit only tips slightly when all drawers are open. As the
drawer
pulls out it catches on the floor and stops it self from over balancing.
We
would still like to warn the service personnel, and are looking for a
symbol
for tipping. I've seen some on large shipping cartons, but can not find
an
example now when I need it. I could not find anything in ISO 3864 that
represents this hazard. If you know of a standard or where there might
be a
symbol on the net, could you please let me know?
Thank you for your assistance,
Ray Russell
