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

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

EU Parliament Unexpectedly Votes to Ban BDEs

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: http://www.eur

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 the

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 Testing La
