Dear Readers:Welcome to the first edition of our EMC Talk, the new EMC Newsletter fromTÜV Product Service. With this new publication we hope to communicateimportant information and news, keeping you informed of changes in theEMC standards and regulatory environment as well as in our activities.

We trust you will enjoy this first issue. If you have any questions on any ofthe related topics please contact us, and we will be happy to help.Jean-Louis Evans - Managing Director

EMC Standards UpdateEN62040-2 2006 - Uninterruptible Power Supplies (UPS)This is a new product standard which replaces EN 50091-2 1995.We are currently in the process of adding this to our UKASaccredited scope under our flexible schedule system. It is worthhighlighting that TÜV Product Service was the first standards-basedUKAS laboratory to have a flexable schedule approved in 2002 andsince this date we have added over 300 revised or new standards.

EN 61000-6-2 2005 - Generic Immunity for Industrial Environments From the 1st June 2008, the 2001 version of EN 61000-6-2 can nolonger be used to give presumption of conformity to the EMCdirective. The revised standard now applies to battery powereddevices that are designed for use in an industrial environment.There is an extension of the RF electromagnetic fields tests to2.7GHz with changes to the voltage variation and short dips test.

2004/104/EC Automotive EMC DirectivePlease be aware that from the 1st January 2009 all new aftermarketcomponents on sale that are intended for fitment to passenger carsmust comply with 2004/104/EC. In our capacity as a technicalservice we would be delighted to assist you with the approvalapplication to the Vehicle Certification Agency (VCA).

CB Scheme goes GlobalAs the scheme is now gaining ever increasing acceptance on aglobal scale we have expanded the EMC scope of our two UK CBTLs(Certification Body Testing Laboratories) to now include IEC 60945(Marine standard) & IEC 61326 (Measurement control & laboratorystandard). There are over 200 test laboratories participating in thescheme in 50 countries across the world including the Americas,Africa, Asia-Pacific, Europe, Middle East and South Asia. Thescheme allows products to be tested in accordance withinternational standards (incorporating any national deviations). Thenational deviations are listed for each country thus addressingspecific regional differences e.g. voltage and frequency variations.

On completion of the testing, a CB test report is issued along with aCB certificate. The certificate can then be used to acquire nationalcertificates in the country you wish to trade in. It is worth noting thata significant number of CB Test Certificates are directly recognizedby Buyers, Retailers and Regulatory Authorities to provide directaccess to global markets. The advantages are clear:

• More rapid testing and certification• More universal product recognition• Acceleration of Product Acceptance• Direct acceptance by the Regulators & Authorities in many countries• Direct acceptance by the Retailers and Buyers• Expanded markets• Faster product movement from plants to markets

Fast Fourier Transform (FFT) workshop

After the recent investment in a newRohde & Schwarz ESU40 receiverTÜV attended the EMCTLA organisedspecial workshop held close to ourBearley test laboratory in Stratford-Upon-Avon. The new receiver hasthe time domain function (FFT) built inand this method of measurement hasthe potential to be the most radicalchange in emissions test methods.The event was well attended andincluded a series of presentations bytest equipment manufacturers andlaboratories with relevant experience.

“Looking for anaffordable solution?TÜV has the answer”

2004/108/EC EMC DirectiveThe new directive has almost reached its first birthday(89/336/EEC was repealed on the 20th July 2007). Throughout thecourse of the year there have been a series of questions raisedand the following is a sample of the common queries:-

What marking is required?The new directive requires the apparatus to carry the CE mark inaddition to type identification, batch and serial number or anyother information allowing for the identification of the apparatus.In addition, the apparatus (if there is sufficient room) oraccompanying documents should have the following:-

• Information on any specific precautions required for assembly, installation, and maintenance that must be taken in order to ensure that when put in to service the apparatus complies with the essential requirements of the directive.

• The name and address of the manufacturer and, if not establishedin the community, the name and address of the responsible person

• In residential areas, there is a clear indication of restricted use e.g. Class A apparatus

What does the declaration of conformity need to include?• A reference to 2004/108/EC• An identification of the apparatus to which it refers• The name and address of the manufacturer and, where applicable,

the name and address of his authorised representative.• A dated reference to the specifications under which conformity

is declared• Date of the declaration • Identity and signature of the person empowered to bind the

manufacturer or his authorised representative.

What documentation is necessary?Annex IV of the new directive now includes a section on technicaldocumentation. This documentation must enable the conformity ofthe apparatus to be assessed against the essential requirements ofthe directive. It must cover the design and manufacture of theapparatus and in particular include the following:-

• A general description of the apparatus• Evidence of compliance with the harmonised standards, if any,

applied in full or in part;• Where the manufacturer has not applied harmonised standards,

or has applied them only in part, a description of the EMC assessment performed including results of design calculations made, examinations carried out, test reports, etc;

• A statement from the notified body, when the procedure referred to in Annex III has been followed.

The technical documentation shall be held for a period of 10years after the last apparatus has been placed on the market.This also applies to the declaration of conformity.

Global EMC Testing Provider

Our laboratories in Europe, Asia and North America make TÜVProduct Service one of the world’s largest independent providersof EMC testing and qualification services. Our internationalnetwork enables us to offer you a complete service at our OneStop sites at Fareham in the UK, New Brighton in the USA or inSingapore. TÜV SÜD is regularly updating its equipment andcapabilities. This newsletter is designed to keep you up to datewith the regulatory and technological changes as they take placeand also to highlight some of our recent investments and servicesthat can help you get your product to market quickly.

New Low Cost EMC ServiceTÜV Product Service is launching a new lower cost service tocomplement its existing broad scope of EMC testing services. Thenew test service will appeal particularly to companies wishing totest their products’ EMC compliance during design and development.

In order to offer this service, TÜV Product Service has invested in alarge G-TEM Cell for EMC radiated emissions and immunity testing,which will form the basis for the new service at its test facility inFareham, Hampshire and will complement its existing 11 EMCchambers.

The G-TEM Cell can accommodate samples of upto 1.2m3 and offers alower cost alternative to conventional screened rooms for radiatedemissions and immunity pre-compliance or confidence testing.However, full compliance radiated immunity testing to EN 61000-4-20 (asan alternative to EN 61000-4-3) and radiated emissions testing can alsobe performed in the G-TEM Cell. Measurements made with a G-TEMCell are accepted for final compliance demonstration by the FCC forPart 15 & 18 radiated emissions testing.

This new service will be highly beneficial to companies who wish toconduct EMC development and investigatory work on their productsas experience shows that many products fall short of mandatory orcontractual EMC performance requirements. Typically, manufacturers’main design focus is on functionality, aesthetics and cost, butidentifying and resolving EMC issues at the earliest possible stage ofdevelopment can save considerable time and money later on in thedevelopment process.

TÜV Product Service’s ‘G-TEM Experience’ allows manufacturersaffordable access to EMC testing whether it be for just a quick check or toinvestigate and modify designs, thereby helping to ensure that productsare on track to pass formal EMC compliance testing at the first attempt.

RAF CESO awards TÜV ProductService a 3-Year Non-Ionising(RF) Radiation ProtectionTraining Course Contract

The RAF CESO (Chief Environment Safety Officer) has awarded TÜVProduct Service a new 3-year enabling contract to provide trainingfor RAF Radiation Protection Supervisors (RPS) who operate radiofrequency and microwave transmitting equipment at RAF Stations inthe UK and around the world. TÜV Product Service has providedthis service since 1998 and has trained some 600 RAF staff to date.

The training addresses the safety hazards arising from non-ionisingradiation also known as radio hazards or RADHAZ. The direct effectof non-ionising radiation on the human body is mainly heating.There are also indirect hazards relating to the ignition of flammablegases, electrically initiated explosives and medical implants. TheMoD adopts the guidance provided by the Health & SafetyExecutive’s, Radiation Protection Division (HSE RPD) on safe levelsof exposure for workers and for the general public. The trainingprovides both theoretical and practical activities to enable the RPSto perform risk assessments, conduct basic measurements andimplement safety controls.

Protection from hazardous levels of non-ionising radiation arecurrently a matter of due diligence by employers and operatorsfollowing the HSE RPD guidance. UK Regulations are due in 2012implementing the EU Physical Agents Directive (ElectromagneticFields) 2004/40/EC). This date was postponed from 2008 byamending Directive 2008/46/EC to allow an impact assessment forcertain medical applications such as MRI scanners.

TÜV Product Service runs public training courses for RF &Microwave Radiation Safety at its Octagon House facilities with thenext 2 day course on 3rd & 4th September 2008. Contact Sandie Peacock for a booking form and syllabus. email: speacock@tuvps.co.uk.

First to offer testing to new EMC Mil standardIn response to the UK Defence industry’s need to qualify its products to the latest American militarystandards, TÜV Product Service has become the first UK laboratory to add Mil Std 461F to its scopeof accredited EMC tests. The service is available now from TÜV Product Service’s state of the arttest laboratory based in Fareham, Hampshire.

TÜV Product Service was able to achieve this quick turnaround time because of its flexible UKAStesting schedule and its early involvement in all new EMC standards, especially for the Defence andAerospace industries. Following Mil Std 461F’s release in December 2007, a comprehensive gapanalysis was conducted between Mil Std 461E and the new F version. As an outcome of this, TÜVProduct Service developed a test method to extend the frequency of the Bulk Current Injection testdown to 4kHz as well as a method for producing a spike which is compliant with the requirementsof CS106. All requirements of ISO 17025 were also addressed.

UK companies can now use a local laboratory to qualify their products to the latest USspecifications and benefit from extremely competitive pricing, a wealth of experience and thequickest report delivery times in the industry.

In-Situ Automated EMCImmunity TestingTÜV Product Service has developed a portable automatedconducted immunity facility, allowing fast, accredited and costeffective testing at your site. Our commitment to developinginnovative testing solutions is focused on bringing lower prices,real value and shorter lead times to the Aerospace industry.

EMC Centre of ExcellenceTÜV Product Service in the UK has been appointed as a Defenceand Aerospace EMC Centre of Excellence within the global TÜV SÜDgroup. In addition to extensive high quality test facilities and verycompetent staff, the UK operations have been recognised for theircommitment to understanding customer requirements, consistentdelivery against customer expectations and developing a culture ofcontinuous improvement in the business.

In partnership with Bath University, TÜV Product Service hasincorporated manufacturing best practice into internal processimprovements. Automation of processes and elimination non value-add activities have significantly reduced production cost whileincreasing already high levels of service.

Examples of industry leading performance include the reduction in fulltest report turnaround to under 5 days from completion of testing,reduction of set-up and changeover times by up to 80% andrecognition by DBERR (Department for Business, Enterprise &Regulatory Reform) for successfully introducing manufacturing bestpractice into a service oriented business.
