Derek,
The horn antenna is an impedance matching device for getting between 50 ohm
lines and 377 ohm free space while launching TEM mode wave fronts.
You could use the commercially available one which has an awful antenna
factor. It's broadband as a result of the ribs placed in the horn.

Hi,
I'd like to construct a wide band horn antenna covering from about 1 GHz to 10
GHz or so.
This is used only to generate a field inside a small EMC Chamber ( about 1
metre by 0.7 metres ), so I'm not worried about gain flatness etc I just
want field;-)
Any thoughts about:

Hello,
testing according to MIL-STD 461D could do it, but real NATO standards are
STANAG 4434, 4435 and 4436.
These STANAGs define tests and limits of equipment designed to be used on
metallic surface ships,
nonmetallic surface ships and
submarines.

I believe that the Mil-Std that you're referring to is now an ASTM Standard
known as F1166-95, titled Standard Practice for Human Engineering Design
for Marine Systems, Equipment and Facilities.
In the list of referenced documents near the beginning of this standard, a
reference to
I don't know if they still do, but USC, Univ of Washington, and Univ of
Cincinnati used to have some courses in system safety and hazard analysis.
I know that this isn't product safety per se but it does address the issues of
identifying, understanding, and mitigating hazards in engineered
Is it permissible to use a surge sppressor that plugs into the IEC320
power connector to provide the suppression necessary to meet CE specs.,
provided that there is a statement that the suppressor must be plugged
in for all countries requiring CE?

Keith,
Without looking at the specifics. Disruption from a discharge can be caused
by direct high voltage gradients, localized breakdown which then applies
direct high voltage, and the often forgotten current injection where the
discharge makes enough current flow that the flow induces a
For those just looking for ergonomics information, there is an excellent
MIL-STD that covers nearly every aspect of human/equipment interface, with
reference dimensions for various percentages of a sample population. It
covers everything from desk height to strength required to turn knobs. I

My 2 cents: I agree, it would make my life easier in compliance engineering
if the EE's ME's would have a little basic understanding of the concepts
of product safety. It seems that they have a general knowledge of EMI/RFI
but the product safety side is still missing.

I found the following website http://ergo.human.cornell.edu/

for the typical product safety professional.

Hello all,
I'm trying to write a set of design guidelines for cables and connectors,
insofar as insulation, clearance and creepage go, that will ensure
compliance with EN 60950 / UL 1950 / IEC 950. I was just wondering is
anyone has seen anything that I might use as a basis, and that would

Many years back TUV Rheinland was involved in the Green Dot program. I the
past few years there has not been too much interest in the program by TUV or
the public.
You may want to check with them.
