In fact a standard for 150 Ohms STP cable does exist but is intended for
FDDI Token Ring applications, to which the ANSI X3.263 standard applies, and
I assume not for Ethernet. Maybe the story I heard was about someone who
used this type of cable for Ethernet.
Although it was a logical guess, the

I don't think what I said differs substantially from what you said other
than I intended to say that where electrical safety of consumer products is
concerned only CSA and c-UL certification is acceptable in Canada.
If you use a consumer product in Canada not so approved to CSA or c-UL,
Both are 8kV air discharge, both require performance criteria B,
but I'd say the current version of 61000-4-2 is more severe.
Doesn't the current IEC 61000-4-2:1995 + A1:1998 version
require a minimum of 50 hits per test point whereas the 1984
version didn't? I don't remember the specifics

Yes -- sort of. Safety certification of IT equipment
is mandatory in both Canada and the USA. However,
both countries accept safety cert

I am interested in learning what is standard 3-phase power for Brazil.
Probably in the 120/208V range similar to North America.
Any help is appreciated..

The EU Parliament voted 6 Sept. to expand the ban on brominated flame
retardants (BFR's) to include pentaBDE's, octa BDE's and deccaBDE's. The ban
would be effective by 2003 rather than the previously proposed 2007
contained in the draft Restrictions on Substances Directive. Check:

David, thanks for the paper. I note that the paper says, "With the
exception of furniture ESD the most severe ESD event is the discharge of a
human through a piece of metal." I understand that a cross vane simulator
was developed to model furniture, but that it has not been incorporated into

Amund,
I believe some additional clarification is warranted.
UL and CSA are private agencies and do not determine what is
acceptable to market goods (ITE) in their respective countries.
This is determined by government bodies.
The U.S. OSHA has approved multiple Nationally Recognized

ULC is the acronym for Underwriters Laboratories of Canada ( a UL

Amund,
UL accept components approved by CSA and CSA accepts components approved by
UL. A CSA approved Power Supply within an end product with UL approval is
no problem any more (that is my experience).

I guess this 150 ohms is from the combination of the 100 ohm characteristic
