Exporting your product may be complex during the “no-transition period” of the new European Directives
The day you “place your product on the market” is what decides whether you must comply with the old or new European EMC or LVD Directives. Therefore, two shipments of the same product shipped and “placed on the market” a day apart will have to meet two different requirements. The definition of “placing on the market” is complex and is not the same as “making available.”
- The latest updates on the EMC, LVD (Safety), R&TTE/RED and other Directives
- Guidance through which directive to use when
- Specifics of the New Low Voltage Directive (LVD)
- D.L.S.’s suggested steps you will need to take, such as generating a new DoC.
This website will keep you updated on the Commission’s additional significant changes so your product will have an orderly placement in the European Marketplace during 2015, 2016 and 2017. For more information call 847-537-6400.

How to Save Money on Compliance Testing
Having your final product fail its compliance test can be costly. Redesigning or adding fixes can be expensive and time consuming, possibly delaying your product to market. How can this additional cost be easily avoided? I can think of three ways.
- Take your product to your test lab early in the design stage so they can point out any potential problems, thus avoiding the expensive fixes or redesigns of a final product.
- Take an EMC Design seminar to become aware of future EMC pitfalls. In the seminar, you will learn the latest updates of current rules and regulations, common reasons why products fail their compliance tests, and problem solving techniques to implement early in the design stage.
- Take the EMC By Your Design Seminar in Northbrook, IL, October 6-8, 2015 and receive a $300 discount for new attendees who register by September 15 or a 50% discount for those who took the class using a prior version of the current textbook Controlling Radiated Emissions by Design, 3rd Edition, who register by September 15.

Brainstorm: Electromagnetic CompatibilityBy Bill Stumpf, as seen in Wireless Design & Development Magazine’s Brainstorm Question, July 2013What are the most popular trends you see in EMC, and how do these trends pave the way for the reduction in electromagnetic interference?I see some trends in EMC that could reduce electromagnetic interference (EMI), and some that could increase it. Engineers seem to be better educated in the process of good EMC design, thanks to classes such as D.L.S.’s EMC By Your Design seminars. Circuits that are designed and laid out correctly, proper termination of shielded cables, and well designed enclosures all contribute to lower interference from digital electronics. However, there are two trends that have the potential to increase EMC interference.The first is related to digital technology. Circuits and microprocessors continue to increase in operating speed, switching power supply designs strive to be more efficient and therefore more prone to higher emissions, and devices are ever more complex laden with multiple functions. The second is the proliferation of products that employ single or multiple wireless communication devices. Everyone wants to operate without wires, and more frequency bandwidth is being opened up for wireless communication.Adding to the mix is that certified RF modules are easy to come by these days, and the integrator may not understand the possible effects of operating multiple radios in one product or in close proximity with other electronic products or wireless devices.

Electromagnetic Interference in Device DesignBy Donald L. Sweeney, as seen on the Medical Design Technology blogThe greatest obstacle to success in the design of a device is that often times the design engineer overlooks the need to keep electromagnetic interference in mind when he designs his device. When a product is not in compliance, it can be interfered with by radio waves emitting from other electronic devices in the home, causing the product to malfunction. Also the waves his product emits can interfere with other medical devices being used causing them to malfunction. To avoid this interference between devices, the design engineer’s finished product must pass a regulatory compliance test. If it fails this test, the design engineer will find it costly and time consuming to redesign his product or to add fixes to bring it into compliance.

The Future of Medical EMC TestingEditorial in Medical Design Technology November/December, 2012 issueRecently a draft changing 60601-1-2 was circulated proposing some dramatic additions to medical immunity requirements. Over the years, medical equipment has had a primary concern that it functions properly in all the environments. This can mean life or death to a patient or even a worker.At the 2002 IEEE EMC Symposium, examples were reported of wireless problems, such as cell phones causing an infusion pump to over infuse epinephrine, a defibrillator affected by a pager, a ventilator affected by a cell phone, etc. I once personally measured the field from a car cell phone at 50 Volts /meter so you can see how that could affect a medical device.Many years ago the only standard available was known as MDS-201-0004 1979. This standard preceded most civilian EMC test standards and was used by our testing laboratory to simulate failure which occurred in the field by customers’ products. Using this standard we could recreate what was happening in the field. Once we had recreated it, we could then develop a solution.I have always found the standard interesting as it not only contained the testing requirements but also the data recorded in the field for various environments. As an engineer, it not only told me what I had to do but why I needed to do the test and at what level.When the European Community developed common EMC requirements for products starting with the proposals in 1989, we began to see standards written to cover many of the phenomena we had been seeing from the field. The earliest requirements for medical equipment were:
- IEC 801-2 Electro Static Discharge, the shock you get in the winter when you touch something.
- IEC 801-3 Radiated electric field 26 MHz to 1000 MHz, what you would see from a radio station or a walkie talkie.
- IEC 801-4 Fast Electrical Transients, the energy seen on power lines when contacts are opened for an inductive load.
- TERA 400/800
- GMS 460
- GSM 800/900/1900
- IDEN 820
- CDMA 850/1900

How is D.L.S. influencing wireless medical devices?Editorial in Medical Design Technology October, 2012 issueAt D.L.S. Electronic Systems, Inc. we influence wireless medical devices by helping to make sure they work when in the field, not interfering with other devices and not being interfered with from other devices. We do this by testing the wireless medical device to see that it meets the regulatory requirements set by the FDA and various world health and safety organizations. In addition, we help develop additional requirements for special cases. For example, one customer made a monitoring device that complied with regulatory requirements but because there were so many of these devices in the hospital, their individual emissions combined and were interfering with a leaky cable receiving antenna. We helped them get their device 20 dB below the limit so they could operate in this environment. (Multiple systems with the same emissions add 20 Log10 of the number of devices in dB. For example, 10 devices can be 20 dB higher than a single device.) At D.L.S. we not only test and consult for EMC and product safety for wireless medical devices; we also problem solve finding practical, workable solutions.

D.L.S. Electronic Systems, Inc. Medical Device Testing and Consulting Compliance ServicesEditorial in Medical Product Manufacturing News (MPMN), September/October 2012 issueD.L.S. offers a comprehensive program for compliance evaluation and testing for the new Third Edition Medical Device Standard IEC/EN/UL 60601-1 and 60601-1-2 for product safety and electromagnetic compatibility that became effective June 2012. D.L.S. provides testing, consulting and certification services for Medical Devices required to meets this standard.Transitional AnalysisD.L.S. is offering a new transitional analysis program with respect to the new Third Edition update of the IEC 60601 requirements for compliance. This program provides a detailed review of testing previously performed to determine if it will show compliance to the new update. This comprehensive review involves not only previous test results, but the methodology and monitoring requirements when compared to a current ISO 14971 risk assessment. This program involves any previous testing, regardless of the performing testing laboratory, or the dates when the tests were performed. Manufacturers of medical devices must meet all the conditions for compliance to these new updated standards.Risk Assessment EvaluationAll new compliance programs are subject to the risk assessment requirements found in ISO 14971. This new requirement is much more detailed and stringent than past compliance projects. The D.L.S. technical staff lends both guidance and assistance in the preparation, review, and formal presentation of the risk assessment that is mandatory for formal certification. The D.L.S. evaluation program involves not the only the risk assessment portion, but details the construction review of design and manufacture to insure an expedient testing program.Early Design EvaluationFor new products coming to market, D.L.S. offers a comprehensive design review to identify non compliant design related issues. This evaluation is recommended at an early stage in the development process, so any potential changes to the equipment being reviewed would have the least possible impact to both cost and delivery of a final approved product. Experienced engineers perform this process working hand in hand with the manufacturer to insure the most process capable design solution.Product Safety TestingWith the new Third Edition requirements, many manufacturers must have older products retested and new products tested to show compliance with these new standards. These standards include U.S., Canada, and IEC requirements. D.L.S. offers a comprehensive one stop approach that includes UL-cUL testing, combined with IEC testing for a global marketplace. This program includes all national deviations for the European Union to show CE safety compliance to the Medical Device Directive and other global requirements as well.Electromagnetic CompatibilityD.L.S. offers Electromagnetic Compatibility Testing in one of the largest EMC testing laboratories in North America, with technical support provided by iNARTE certified engineers, for both emissions and immunity required for formal compliance and approval. Testing includes both radiated and conducted emissions, and well as radiated and conducted immunity tests for North America and IEC requirements, supporting a global marketplace.SummaryD.L.S. offers one of the few places where detailed engineering support is provided at all stages of the compliance process, from initial design, to final formal compliance testing, and all steps in between. For 30 years, the value added D.L.S. service oriented staff has meet the aggressive demands of the immerging medical device marketplace, keeping pace with the latest in updates to the growing global compliance requirements.

Once a new medical device idea is formulated, what is the critical first step to help ensure its success through to market launch?Editorial in Medical Design Technology, May 2012 issueTo ensure its success through to market launch, a newly formulated medical device will need an early stage design review, addressing electromagnetic compatibility and product safety requirements. This review is a critical first step because it eliminates regulatory compliance design flaws and identifies applicable standards early in the design phase, thereby eliminating costly changes during testing of the final product and delays in the delivery of the new device. This early stage design review will cover worldwide EMC and Safety directives, including FCC, CE, UL, CSA, FDA, IEC, CCC, and other government and regulatory agencies. This review will allow the device to meet regulatory compliance in a time-efficient, cost-saving way during final testing. We have found by addressing EMC and Product Safety requirements early in the design stage, we have saved many medical manufacturers the cost, frustration, and loss of time of trying to add fixes and design changes to a product that is out of limits or that requires Product Safety changes.

Influencing Wireless MedicineIn response to Medical Design Technology’s question, “How are you influencing wireless medicine?” our Senior EMC Test Engineer and OATS manager, Bill Stumpf, responded with the following:Wireless technologies have an important role in medical applications such as asset tracking (RFID), wireless controllers, patient monitoring, two-way radios, and wireless data transfer. It is imperative that manufacturers of these wireless medical devices address the issues and concerns relevant to the safe and effective use of radio frequency (RF) as required by the many Medical Standards and the hospital environment. As an Electromagnetic Compatibility and Product Safety lab offering testing, consulting, and certification of wireless devices, we get manufacturers through regulatory compliance hurdles. In this way we provide a streamlined process of getting new wireless medical technologies on the market in a timely and cost effective manner. By testing for RF emissions, Immunity to Interference, and Product Safety, we are helping to provide assurance that the wireless device will work reliably in the environment for which it is intended, and that it will be safe for the user and patient. As a test lab we are helping to make these wireless technologies available to the medical industry.

Bill Stumpf, D.L.S. Site Manager,
Helps Write New Standards
The role of ANSI Accredited Standards Committee C63® – EMC is to develop definitions and methods of measurement of electromagnetic noise and signal strengths, determine levels of signal strength, levels of unwanted sources, limiting ratio of noise (and/or unwanted sources) to signals, and develop methods of control of, and guidelines for influence, coupling and immunity. There are currently twenty C63 standards developed by this committee or currently in development or re-issue. Bill is an active volunteer on Sub-Committees SC-1 Techniques & Development, SC-6 Accreditation/Conformity Assessment, and SC-8 Medical Device EMC Test Methods. Development of C63.10 is being done by members of SC-1.
Work on the C63.10 standard began in 2006. The C63.10 standard is intended to consolidate and develop procedures for testing the compliance of a wide variety of unlicensed wireless devices. Until now, the test procedures were scattered about in different FCC publications, application notes, and guidance documents, which has caused confusion regarding the testing of devices and inconsistent test results. The first edition of this standard is slated for publication later this year.

HHA Safety Standard 60335-1’s new EMC requirements significantly increase severity of immunity testing.A recent amendment to the IEC/EN 60335-1 Standard, which covers household and similar appliances, added EMC requirements to this safety standard. These requirements apply to electrical appliances which incorporate protective electronic circuits, those which have a switch with an off position obtained by electronic disconnection and those with a switch that can electronically be placed in a stand-by mode. The new requirement significantly increases the IEC 61000-4-x severity levels mandated in the EMC standard EN 55014-2. Some of these requirements became mandatory on October 1, 2006, while the rest are currently scheduled to become mandatory on October 1, 2007.
+ 1kV Differential Mode (line-to-line) + 2kV Common Mode (line-to-ground)For products with these electronic switches, the levels are increased considerably to:
+ 2kV Differential Mode (line-to-line) + 4kV Common Mode (line-to-ground)In addition to the surge test example above, there are many other immunity tests affected, including radiated susceptibility and ESD.Since there is no grandfather provision, manufacturers of household and similar appliances should have their products evaluated, and potentially tested, immediately. This will assure they are prepared for the new IEC/EN 60335-1 EMC mandates becoming mandatory in October 1, 2007. For more information call Steve Grimes at 847-537-6400.

NARTE Exam Tips
Engineers and technicians who want their NARTE certification now have a painless and easy way to prepare for the NARTE exam. D.L.S. Electronic Systems, Inc. in cooperation with NARTE (the National Association of Radio and Telecommunications Engineers, Inc.) has developed a web site with a “NARTE Question of the Week.” Each Monday a new question will be listed on the web site. Just copy/click the link in your web browser: iNarte Question of the Week and bookmark it as a favorite. Review the question of the week. Decide on your answer and click to see if you are correct.
Here are some tips:
Don Sweeney, Sr. EMC Engineer and NARTE Certified EMC Engineer, who took the test to prove to himself that he deserved being grandfathered as a NARTE engineer and technician, suggests that you consider the following while reviewing the question.
- Read the question. Then ask yourself, “What are they really asking for?”
- Read all the answers. Don’t stop at the first one you come to that looks correct, but instead choose the best one after reading all the listed answers.
- As you go through the questions week after week, think about what resource materials you might want to bring with you to the final test, since it is an open-book test.
When you begin to feel prepared for the test, look for a link to NARTE enabling you to get your application form and other materials. This link is on the question page.
For additional information contact Carol Gorowski at D.L.S. Electronics Systems, Inc. at (847) 537-6400.
What is NARTE EMC certification and why would someone want it? In the late l980’s the Navy through NAVAIR wanted a way of knowing their equipment was being tested correctly. NARTE, the National Association of Radio and Telecommunication Engineers, was contacted to set up a program for both EMC Engineers and Technicians. Initially through a grandfathering process, the certification requirements could be met by personnel having a specific level of experience and three individuals in the industry to vouch for their level of experience and expertise.
After the initial grandfathering was over, all future NARTE EMC engineers and technicians are required to pass a written examination. The exam takes an entire day and covers many areas of EMC. The standard way to prepare is to order study guides and work sample questions.
With D.L.S. now listing the NARTE question of the week on the web, a prospective engineer or technician can simply click the web site and study a new question each week. This should be a painless and simple way for someone with the basic knowledge and experience to prepare for the examination.

D.L.S. Now a Conformity Assessment Body
for the EMC and R&TTE Directives
D.L.S. Electronic Systems, Inc. has been designated as a Conformity Assessment Body (CAB) for the EMC and R&TTE Directives under the Mutual Recognition Agreement between the United States and the European Union. Under article 10(2) of the EMC Directive, a CAB in the US can perform the same operations as a European Competent Body.
D.L.S., One of the first labs to complete EU EMC testing and to provide Technical Construction Files (TCF’s) for their customers, is now recognized as a CAB. Having been nominated for CAB statues by National Institute of Standards (NIST) in 1998, we have completed the preliminary phases and may now operate independently of other entities to meet customer’s needs. The implication of the CAB status is that it qualifies D.L.S.to operate as the equivalent to a European Competent Body for EMC and Notified Body under R&TTE for radio transmitters.
During the past 24 months D.L.S. has been doing various EMC activities such as testing products, writing Technical Construction Files (TCF’s) and submitting them to a European Competent Body during the transition.
In its role as a CAB (a European Competent Body equivalent) D.L.S. generates and reviews TCF’s and issues certificates of conformity to manufacturers without the involvement of another European Competent Body. Performing as a Notified Body, D.L.S. can also advise customers on how to meet the R&TTE Directive for radio transmitters.
D.L.S. which has been in operation for the last 17 years, is one of the largest EMC labs in the world under one roof and can accommodate almost any size project for EU CE Marking, FCC, EMC and radio transmitters.
