Re: EMC Directive + UK Regulations - take 2
Bill, This is an intriguing question. According to the legislative record publicly available, this change of text was part of what the Commission put into the revision mill and it was not challenged by Parliament or Council. Ref http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=COM:2002:0759:FIN:EN:PDF http://eur-lex.europa.eu/LexUriServ/Le UriServ.do?uri=COM:2002:0759:FIN:EN:PDF There may have been a preperatory study that prompted the change, or it may have occured unilaterally by the Commission person who had the dossier at the time. The above linked document uses the term end user several times and it may give you some idea what they were on about. You may well be able to contact the Commission on this point and get some satisfaction. If you do, be sure to share ;-) Cheers, -- Lauren Crane (mr.)

Re: EMC Directive and solenoid valves
I seem to recall that one of the earliest EMI problems was one that came from solenoids (well a version of one that held the core stationary and used the coil discharge). Resistor wire and resistor plugs reduced the problems to acceptable levels in cars. If you can find any of these parts without the resistance, substitute them into your car and listen to what happens. - Bill --- On Tue, 9/22/09, Scott Douglas sdougla...@socal.rr.com wrote: From: Scott Douglas sdougla...@socal.rr.com Subject: Re: EMC Directive and solenoid valves To: Price, Edward ed.pr...@cubic.com Cc: emc-p...@ieee.org Date: Tuesday, September 22, 2009, 1:13 AM In a past life I had a real problem with a solenoid causing serious EMC, primarily from the coil discharge.

While this is certainly true, any EMC test result is possibly very dependent of the applied enclosure/supply during test, making the results at least very unreliable. Unless the manufacturer is able now to produce operational motherboards that pass emission tests without enclosure ! Regards, Ing.

RE: EMC Directive Applicability to Mother Boards
Devil's Advocate and EMC amateur I am. For both personal use and for test bench automation at the factory, the MB is chosen with attention to EMC emissions and immunity. So this stuff can be considered important to both residential and industrial end-users. It is not unreasonable for the non-engineer end user to expect that the mb will not require installation in a steel vault with a beryllium gasket around the cover and not be subject to total destruction from a minor ESD event.

RE: EMC Directive requirements for LINEAR power adapter
Mark, I would say not. Your adapter includes diodes, which are a form of switching device and will cause interference of some description to an extent that depends on the speed of the diodes. An EM passive device would be something like a filament lamp or an electric heater (providing it doesn't have a thermostat); i.e. items that draw a constant current at supply frequency. You are fortunate that you are considering a low power device, otherwise you would definitely be having to consider harmonic emissions; a simple rectifier/capacitor configuration generates those very well.

If it is not active, will it be safe to assume what it will be excluded from 89/336 directive based on EU guidelines? No, because it emits mains harmonic currents and, depending on the type of diode in the rectifier, perhaps emits conducted noise above 150 kHz. However, it's certain that its mains harmonic emissions are subject to no limits according to IEC/EN 61000-3-2 (lower bound for the application of limits is 75 W active input power), and 99.99% certain that it meets the limits for conducted emissions above 150 kHz. So, although it's not *excluded*, it can safely be claimed to meet the essential requirements of the EMC Directive without testing.

Brian, If I was buying a product for use at home and had to wait until I had put the CD in the computer before finding out it was NOT suitable - then I would be pretty hacked off.

Re: EMC Directive interpretation
http://www.ieee-pses.org/symposium http://www.emc2004.org/ I read in !emc-pstc that =?iso-8859-2?Q?Konrad_Stefa=F1ski?= kstef...@poczta.onet.pl wrote (in 002d01c46bfd$50d39d00$0301a8c0@konr ad) about 'EMC Directive interpretation' on Sat, 17 Jul 2004: I would like to ask you how to obtain conformity with EMC Directive to the following product: Tension-converter used in tension-meters or weighting devices. There is a separate Directive for weighing machines, and your product may be within its scope. It is only resistive device, It consist only resistors which could change resistance with tension changes. These resistors are serially connected. It has no other electronic and electric parts in its construction. This converter could only work with other device, but it may be selled as stand alone device. So my questions: 1. Does this device (converter) lay under scope of EMC Directive? Yes, is the simple answer. You might be able to make a case that is doesn't, but it would be difficult, and there would be a permanent risk that your case would be successfully challenged. 2. If YES, is this necessary to do tests in accordance with EMC harmonized standards to show conformity with directive ? I think that this device meets EMC Directive requirements without any tests (only resistive character). You probably don't need to do any tests in order to justify the Declaration of Conformity. But it would be helpful commercially if you could claim, on the basis of tests, that it did not affect the EMC characteristics of whatever it has to be connected to in order to use it. The appropriate tests are probably radiated emissions, ESD and radiated immunity. 3. If NOT, is this device a EM-passive component? 'Passive' is a misleading word. Your device is passive, but it may not be 'benign', that is, it may affect the EMC characteristics of whatever it is connected to. The above points probably apply to ANY device that has no active components and is connected to something else in order to work, if it is placed on the open market by itself. -- Regards, John Woodgate, OOO - Own Opinions Only.

RE: EMC Directive
Hi Joe It's much more simple then that. The EMC directive references harmonized Standards list. The list of harmonized standards is listed in the Official Journal = LAW. The date of publication of the list is the date that the standard may be used for the first time. The list mentiones dates of withdrawal for older standards = LAW Logic thinking does the rest.

The Directive does not go into detail on DOW's of the standards. Take a look at the Guide to the implementation of directives based on the New Approach and the Global Approach Section 4.5 discusses revisions to the standards. It states ...the relevant European standard organisation lays down the date of publication at national level of the revised harmonised standard, and the date of withdrawal of the old standard. The transitional period is normally the time period between these two dates. During this transitional period, both harmonised standards give presumption of conformity, provided that the conditions for this are met. After this transitional period, only the revised harmonised standard gives a presumption of conformity. These guidelines can be downloaded from the following site. http://europa.eu.int/comm/enterprise/newapproach/legislation/guide/document/ 1999_1282_en.pdf Regards Joe Martin John Juhasz John.Juhasz@GE-interloTo: 'emc-p...@ieee.org' emc-p...@ieee.org gix.com cc: Sent by: Subject: EMC Directive owner-emc-pstc@majordom o.ieee.org 08/21/2002 10:09 AM Please respond to John Juhasz I know this has come up before, but I need to quote chapter and verse. In a conversation with an acquaintance of mine, the EMC Directive became a topic with DoW and use of superceded standards for presumption of conformity becoming a contentious area. I maintain the following understanding: A product is evaluated to standard A. At some point standard a can no longer be used for presumption of conformity (DoW) and standard B must be used. Therefore if a product is still being manufactured for sale after the DoW of standard A, then the product must be re-evaluated according to the new standard B. (An exemption being those items returned for repair and not modified/updated/upgraded). If the product was no longer produced and placed on the market after the DoW then there is no issue. My acquaintance notes that if the product was tested to standard A, as long as it has not been 'updated, modified, or changed in anyway' since the initial compliance test, it can still be manufactured and placed on the market after the DoW without re-test. I believe that my understanding is the correct one. I tried to locate it in the EMC Directive itself but I can't seem to find it. Am I incorrect? John A. Juhasz GE Interlogix Fiber Options Div.

I read in !emc-pstc that John Juhasz john.juh...@ge-interlogix.com wrote (in 2A1845F4CDE8D511B4400090279C703BFB6A53@BCTEXC10) about 'EMC Directive' on Wed, 21 Aug 2002: I believe that my understanding is the correct one. I tried to locate it in the EMC Directive itself but I can't seem to find it. Am I incorrect? Your understanding is correct. The 'dow' should be the 'docopocotss' - 'date of cessation of presumption of conformity of the superseded standard', but even Brussels jibbed at that. The relevant text is not in the Directive, because it applies generally, not just to EMC.

Re: EMC Directive
John, Article 7 in the Directive discusses using national standards to meet the protection requirements of the Directive. The Directive does not go into detail on DOW's of the standards. Take a look at the Guide to the implementation of directives based on the New Approach and the Global Approach Section 4.5 discusses revisions to the standards. It states ...the relevant European standard organisation lays down the date of publication at national level of the revised harmonised standard, and the date of withdrawal of the old standard. The transitional period is normally the time period between these two dates. During this transitional period, both harmonised standards give presumption of conformity, provided that the conditions for this are met. After this transitional period, only the revised harmonised standard gives a presumption of conformity. These guidelines can be downloaded from the following site. http://europa.eu.int/comm/enterprise/newapproach/legislation/guide/document/1999_1282_en.pdf Regards Joe Martin John Juhasz John.Juhasz@GE-interloTo: 'emc-p...@ieee.org' emc-p...@ieee.org gix.com cc: Sent by: Subject: EMC Directive owner-emc-pstc@majordom o.ieee.org 08/21/2002 10:09 AM Please respond to John Juhasz I know this has come up before, but I need to quote chapter and verse.

RE: EMC Directive
Partially Wrong. The only reference you will have to use in Europe with the Compliance matters and standards is the published list of Harmonized Standards . Dates (DoW) printed in the standard itself may or may not be the same but are irrelevant in CE Europe. The reason for this is that standards are private documents created by private organisations. The EMC directive is law as well as the list of harmonised standards. This list is available at many sources . The list includes dates on which any standard is superseded by it' successor. The product will have to comply with the new standard regardless of any modification. If you or any client does not agree, the route 10.2 of the technical construction file may be used. A NB will review your design and measures that have been taken to comply with essential requirements. Often this will lead to the same result as using the new standard, especially if new phenomenae are to be tested in the revised standard which were not in the earlier. No escape route though, but may be used if injustice would have been done to your product. The EMC directive directly points to this list of harmonized standards, and that should justify that your opinion is right.

RE: EMC Directive/Repaired Apparatus
Joe, I've given this topic a fair amount of thought. I believe the intent of the new approach directives is only for equipment being put into service for the first time. My understanding is if the repair is only a repair and not an upgrade of any kind, then you may simply put it back into service at the same place where it was originally placed into service. There are a number of documents that give good guidance at: http://europa.eu.int/comm/enterprise/newapproach/index.htm There are a number of documents linked to this page and I suggest a full reading before deciding a course of action. I got the most useful information at: http://europa.eu.int/comm/enterprise/newapproach/legislation/guide/legislati on.htm This is a guide to the implementation of the new approach directives and there is a single PDF version near the top of the page. In this guide I found several items of interest plus a fairly good clarification of exactly what is placing on the Community market (or put into service) for the first time. This would seem to exclude repair, refurbishment or renovation of products. The implications are many and here are a few that come to mind, 1) I believe products which have been repaired without changing the original performance, purpose or type, are not subject to further assessment. 2) I also understand that if you are installing any sort of upgrade to the product which was made available after the applicable directive came into force, then the entire product needs to be assessed to current requirements. 3) I do not believe you or the company doing the repair are allowed to keep an inventory of refurbished service spares on hand as the guidance document seems to indicate that the original (serialized) unit must remain where it was first put into service (i.e. no stock piling). 4) Exactly how one provides markings and a declaration for this situation, I cannot say ... 5) Applicable product directives take precedence over provisions set out in this guide. For example, if you are using products to the Medical Equipment Directive, then you should be familiar with discussion it has on repair and refurbishment. Regards, -doug --- Douglas E.

RE: EMC Directive
Be careful of declarations that include a specific model manufactured by another company. Without engineering control or intercompany agreements the other product could change without notice, technically negating your declaration. Nothing prevents the competent body from insisting on a cooperative agreement between both companies to assure future compliance. Is this related to your earlier question about an UPS?

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 .

An analysis of potential EM threats to an EUT and potential victims of the EUT's emissions, when presented to the competent body in the TCF, can result in cases being made for using hand-held radios for RF immunity testing, radiated emissions testing outside the building housing the EUT (instead of inside where reflections and power lines distort the field), and using current probes to measure line conducted RF emissions.

Use CISPR voltage probe Current draw in excess of available EFT surge coupling network capacity. EFT, use 33nF cap. Surge,? 3 or 10m EUT to antenna distance not achievable and/or high ambients. Lab type radiated immunity not practical due to interference potential. Large equipments requiring multiple antenna locations or search and optimize considerations for radiated emissions. I am especially interested in potential alternate techniques for radiated immunity. Potential solutions may include ad hoc testing using actual transmitters, eg cell phones, VHF, etc. Testing at discrete frequencies of known public broadcast bands. Extended frequency conducted immunity testing. If you have thoughts or other considerations, please respond to the group.

Re: EMC Directive and Small DC motors
I agree with Robert, that you generally have to test your product. Especially because conducted disturbancies on the power supply lines could induce disturbancies on other signal and power supply lines in a system. Since one can expect only conducted emissions you only had to do this test ( I assume you have no electronics in your product). The costs for such a test should be less than 800$. Regards George Robert F. Martin ITS/QS-Box wrote: While it seems simple enough, the product is more than just a component. It can be considered an apparatus by EU standards because it has an intrinsic function. If the pump was restricted to a specific application, and would not work without it, you might get away without testing it. Because that is not the case, and they seem to have general purpose uses, then CE marking is appropriate if you sell into the EU. If you only sell to people (in the US) who incorporate the pumps into products which THEY sell in Europe, then any requirement for testing/marking is contractual, not regulatory. As for the problems experienced with previous testing, you should, in fact operate the motor with a battery. If the power supply was the source of the problems you had, they should go away. With regard to testing the new vendor, you are obligated to demonstrate compliance of the new motor.

The old VDE CISPR 22 requirements were not unlike the present harmonized EMC standards. Many European countries required products to meet IEC 950 or their equivalent before the Low Voltage Directive. So the CE marking is mostly a difference in required documentation, not a difference in the design of the products. It is my understanding that NO ITE products may now be accepted by EU member states without CE marking attesting to cconformity with the EMC and Low Voltage Directives.

Re: EMC Directive
I agree with Tony that a RAID (not RAID Array - there's no such thing!) is unlikely to be found in a residential installation, with one caveat. The RAIDs that my company produces are becoming used in an increasingly large amount by people producing digital video. Most of these people either work out of their homes or they have shops in small offices located in residential areas. The only good thing I can see from this situation is that they don't use RAID 3 or RAID 5 units. They prefer the speed they get from a RAID 0 system. Thus, we qualify our RAID 3/5 systems to class A (since they're used almost exclusively by banks, magazines, newspapers, and the sort), and our less complicated RAID 0 systems to class B for EMC. We qualify the safety of all of these systems to the various variations of the 950 standard, as required by the markets in which we sell. 60MHz systems can be problematic, especially if you're running single-ended SCSI. I hope you're not, since the 60MHz stuff has a lot of problems that are EMC and non-EMC related if you're single-ended. Are you running 60MHz interfaces on the disk drives, the RAID controller, and the host? If so, you have fewer problems than if you're mixing in fast SCSI with Ultra (should I have mentioned that word?). Well, good luck, Philip. Disk drive systems are such fun! Steve Chin FWB, Inc.

RE: EMC Directive
Hi, A RAID Array is not the type of product that will turn up in a residential application. It is not under the scope of EN 60555-2. It is under the scope of the 61000-3-2 which was published in the OJ last September. That topic has pretty much been beat to death on this alias, but we could revive it and smack it around all over again (not this again!!!). This product falls squarely under the category of ITE and thus is subject to the Generic Immunity and Emissions Standards and EN55022. Depending on how you define its use environment, you can qualify it for Class A EMI with restrictions on use in the instruction manual or Class B EMI for unrestricted sale and use. Those restrictions for Class A would specifically exclude use of the product in residential environments and perhaps even exclude powering the product of power supply mains which are shared by residential users. The design considerations are not really special wrt to other ITE equipment. Of course all of the considerations on what to do to design a product with 60 MHz fundamentals within can and does fill books. Hopefully you or someone else in your company has some experience with EMI design or you may want to hire a good consultant in the design phase of the project. I think there are quite a few good ones on this alias. Regards, tony_fredriks...@netpower.com -- From: PS To: emc-pstc Subject: EMC Directive List-Post: emc-pstc@listserv.ieee.org Date: Tuesday, April 16, 1996 5:51PM To Whom It May Concern, I got details of your forum through an e-mail transmission to one of my associates, by Ron Pickard. I would appreciate any information you may be able to supply concerning the EMC Directive, in relation to possible problem areas when developing our new enclosures for RAID porducts. The basic enclosure houses a controller (crytsals on this controller operate at 60 Mhz max.) And three 150W hot replacement PSU's. What sort of areas should we pay particluar attention to in the design? Would it be correct to state that the PSU's fall into the EN60555-2 standard? As it still seems that the EMC Directive is very vague in this country I would be glad of any information you may have available. Thanks and best regards, Philip Scott - Cork, Ireland. phi...@glenm.ie
