KGS TechnoFair 2006
Osaka, Tokyo and Nagoya, November 2006
The Automotive EMC Network, in the form of Martin O'Hara, was invited to present a paper at the 21st KGS TechnoFair in Nagoya, Japan on 21st November 2006. This was the third event in the KGS Technofair calendar, the previous week 2 events had also been held in Osaka and Tokyo. A regular of the Automotive EMC Conference Ayhan Gunsaya of Ford Motor company and AEMCLRP committee was invited to present a paper at the Osaka and Tokyo KGS Technofairs on 14 and 17 November 2006.
The KGS TechnoFair is an annual EMC and related technologies closed seminar series organised by Kitagawa Industries Co. Ltd. Invited customers are provided with a high level of technical presentations by leaders in the fields of EMC, thermal management and similar related areas.
The following are personal reflections by Ayhan Gunsaya and Martin O'Hara about the events at which they presented.
Introduction to Automotive EMC, European Legislations and AEMCLRP
This was my first to trip to Japan and I was really proud to have been invited to give two key-note lectures in this prestigious event. I was
astounded by the size of the audience in Osaka (approximately 250) but was completely taken aback by the 450+ crowd in Tokyo.
In terms of the country, I was really impressed with the level of hospitality, kindness and respect they afforded to me and to one other. I must mention my genuine 'surprise and delight' about the fully automated toilets complete with heated seats and 10-button electronic controls for optimised personal cleanliness. Travelling on the Shinkansen (Bullet) Train and visiting the Hiroshima Peace museum where the first Atom-Bomb was dropped were the other two highlights of the trip.
Here is a brief synopsis of the lecture given in Osaka and Tokyo
The lecture started with a brief introduction of automotive EMC environment. The automotive electromagnetic environment faced by electronic modules is very challenging as it contains intentional RF transmitters, accidental sources of emissions as well as conducted transients and electrostatic discharges. It is necessary to put in place certain requirements both at vehicle and component levels to ensure electronic equipment can operate in harmony with each other and without interfering with broadcast and radio communication services.
The second topic covered the Automotive EMC Laboratory recognition Program (AEMCLRP).This program was developed jointly by personnel from DaimlerChrysler, Ford Motor Company, and General Motors Corporation to establish common criteria for the evaluation of the competency of automotive EMC laboratories. Laboratories which wish to perform official sign-off tests for the participating vehicle manufacturers have to achieve accreditation to AEMCLRP by a third party such as A2LA, JAB or UKAS. Then an application is made to each vehicle manufacturer for recognition.
The focus then moved to the European EMC directive introducing the recent revision to the automotive European Automotive EMC directive (2004/104/EC. Key changes to the directive were discussed as follows;
The upper test frequency for radiated immunity has been extended from 1GHz to 2 GHz and test modes increased to a minimum of two but the limits remains at 30 V/m.
The scope of radiated emissions has been extended to cover all devices capable of generating emissions that can be turned on permanently. The broadband requirements are now applicable to all types of engines including diesel and hybrids whereas 95/54/EC only covered spark ignition (gasoline) engines.
However, the most significant change is with respect to RF transmitters whereby the vehicle manufacturer must provide a publicly available statement clarifying suitability of a vehicle type for radio transmitter installation.
The lecture was concluded with a discussion on vehicle level EMC testing
especially with a focus on off-board radiated immunity tests.

A Generic Automotive EMC Specification
The above is the title of the paper I was invited to present at the KGS Technofair 2006 in Nagoya Japan, this would also be my first visit to Japan so I was both excited and nervous about making a presentation to a Japanese audience. The paper is an attempt to drive a straight line through the plethora of automotive vehicle makers EMC specifications to get some "average" specification that would satisfy most of the requirements of most of the global automakers. The paper also makes remarks about the difficulty of obtaining the EMC specification of Japanese vehicle makers, and I was a bit concerned that this might not go down too well, but in fact the Japanese EMC test service providers and many tier 1 suppliers also have difficulty obtaining this information, so much to my relief this was a sentiment shared by the audience.
The output from the work is being made available on the Automotive EMC Network as an open source document, many of the audience were surprised that the information was going to be made freely available and few had heard of AutoEMC.net before the presentation. The questions after the presentation varied, many were about the test methods adopted, all ISO or CISPR methods hence readily available. Similarly there were several asking if the work had been endorsed or encouraged by any of the vehicle makers, unfortunately none were aware of the work until the Automotive EMC 2006 conference and none were involved. The exclusion of the automakers was deliberate as the time this would have added to the project would have been unacceptable and the makers themselves have some specific non-standard tests that I was not willing to include in a generic specification. Also while free from automaker involvement I was able to pick-and-choose the best methods from each automaker, and to avoid errors some have made such as use of IEC 61000-4-2 for ESD testing.
The audience was one of the largest I have ever presented to, approximately 150 or so people were in attendance. This is more a reflection of the excellent organisation of KGS than my paper as they had obtained similar attendances to their other presentations in Osaka (200+) and even more (450) in Tokyo. I feel this is also a good indication of how dedicated the Japanese are to continuing the professional development of their engineers, when you look at the total European attendances to the Automotive EMC Conferences only being in the 40 or so region, you realise just how committed the companies and engineers in Japan are to furthering their knowledge.
KGS (Kitagawa Industries Co. Ltd) offer an EMC test service capability to the Japanese market, they have VCA technical service accreditation and hence are capable of performing EU Automotive EMC Directive testing and certification in Japan and with partners in Europe.
