ground plane size for EN 61000-4-4
List Members: Paragraph 7.2.1 of EN 61000-4-4 (Electric Fast Transient/Burst Immunity) states the minimum size of the ground plane will is 1m by 1m which of course is 1 square meter. All other EN 61000-4-X standards state the ground plane will be at least 1 square meter with no mention of specific dimensions. I would appreciate any comment on the apparent requirement for a 1m by 1m ground plane as our ground plane is 36 inches by 6 feet.

WEEE directive
It has been reported that the 4th draft directive on Waste Electrical and Electronic Equipment (WEEE) was set to be approved the first week in June although it must go through the European Parliament before final adoption. Does anyone know if this draft is available on the web? I was unsuccessful in finding it.

RE: Radiated Susceptibility up to 100 GHz
-Original Message- From: Brumbaugh, David [mailto:david.brumba...@pss.boeing.com] Sent: Monday, June 12, 2000 8:18 AM To: 'emc-pstc' Subject: Radiated Susceptibility up to 100 GHz List Members: Does anyone have experience performing radiated susceptibility (immunity) testing at frequencies up to 100 GHz? If so, what labs are equipped to provide this service, and what field levels are achievable? Thanks, DB Dave: Cubic can perform Radiated Immunity testing from 10 KHz to 18 GHz, with any modulation, at a minimum level of 200 Volts per meter. Beyond 40 GHz, you get into very expensive territory. If you need continuous tuning coverage, that's even tougher. You might want to try Cincinnati Electronics or RB Associates.

Telephone equipment approval
I have heard that BABT approval for telephone equipment is no longer required in the U.K. and is replaced by a new directive for all EEC countries.

RE: EFT/Burst
You are correct for purposes of COMPLIANCE to EN55024 and application of a CE Mark, you test each line with respect to a reference ground (PE), but as I'm sure you're aware, a customer can ask for whatever they think is relevant. Mike Hopkins mhopk...@keytek.com -Original Message- From: Roncone Paolo [mailto:paolo.ronc...@compuprint.it] Sent: Wednesday, June 07, 2000 11:46 AM To: 'emc-p...@ieee.org' Subject: EFT/Burst Group, we are currently discussing with one OEM the interpretation of EFT/Burst test requirements per EN55024 and EN61000-4-4 to a printer. Specifically we are discussing the requirements of application of bursts to AC power lines. Our understanding is that they must be applied between each (single) power supply conductor and reference ground (or protective earth), as specified in EN61000-4-4 section 7.3.1. Also fig.4 and fig.11 in the same document seem to confirm this. Our OEM customer says that all combinations of phase, neutral and protective earth should be tested. They actually tested both singular AC lines and also more than one AC line. The printer passed the test in the first mode and failed in the second mode. Any comments / interpretations would be highly appreciated. Paolo Roncone Compuprint s.p.a.

RE: EU equivalent limits to FCC Part 15C
The standards are developed by ETSI (www.etsi.org http://www.etsi.org ). You may download up to three standards for free. Generally, the FCC and ETSI limits are quite different. The measurement methods are also different. However, I can tell you that the ETSI limits for short range devices are higher. Note that not all EU countries accept the ETSI limits in all bands; e.g., Germany. You will also need to check out the CEPT/ERO Decisions and Recommendations at www.ero.dk http://www.ero.dk to see how the limits and bands vary throughout the countries.
