Hi group,
can anybody provide some information on EMC requirements for machines
(industrial equipment) in South Africa?
Thanks in advance
George

In looking at meeting CSA and UL spacing requirements for some of our PCB's

conformal coatings (allowing reduction of spacing) have come up. The

Eric,
We have run into the same problem here at Emulex. Our Host PC's need to
provide Class B compliance - something that seems hard to find these days.
We have evaluated many, many, many PCs, and in the end, decided on a

Our requirements are more stringent than most,
Hello everyone,
Is anyone interested in a RF/EMI shielded enclosure? Size is 10'x8'x8',
manufactured by Universal Shielding Corporation from Deer Park, NY. We
have no use for it as we do all our testing at an independent lab. Price is
negotiable, we want to move the enclosure out of our

We manufacture Scientific instruments which
operate under Vacuum. We have an entry chamber which is let up to
atmosphere generally using nitrogen from a cylinder with a regulator.
We use EN 61010 as our standard for LVD compliance and a question has

Dear All,
Could any body out there tell me if there is any current legislation for

PSNet Richard,
The legal questions can only be answered by European lawyers and
courts. As far as I know, there have not been any cases which looked to
hold non-Europeans responsible to the extent they would be fined or serve
jail time. If it is a major problem we can expect
Hi Allen:
Does anyone know how to calculate minimum distances between traces on
a printed circuit board that would allow one to pass the dielectric test
at a given voltage? Or has anyone taken any empirical data that would
shed light on this topic? Also, would trace width have an impact
Hi there,
I'm looking for locations that can help me HIRF test an LRU. This unit is
mounted outside the fuselage on a rotary aircraft. Not a really nice place to

Not to beat a dead horse, but:
While your observations on the political side are very interesting and all
too true, I still stand by my comments regarding immunity testing of

I fully support Lacey's views about performing some immunity testing on the
products, in order to improve their reliability.
Long before FCC/EU implemented EMC requirements on the electronic products,
IBM had formulated emissions and immunity standards for their products.
