I am unsure if they have requirements specifically for industrial equipment.
For commercial equipment, they are accepting test data based upon CISPR or
its clones. I don't think they are being too critical since they even
accepted some of our FCC test reports. You can contact Wimpy Lyons of the

In looking at meeting CSA and UL spacing requirements for some of our PCB's
(in power supplies up to 600 V) some questions concerning the use of
conformal coatings (allowing reduction of spacing) have come up. The
information that I am seeking is for both CSA and UL; the wording that they

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

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
Gateway 2000 Tower.
Our requirements are more stringent than most, bec
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.
Even now some of the IB
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 warehouse

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
"fly-by-wire" (100% electronic vs. electronic/electromechanical controlled)
products. These products are potentially f
Hi Everybody
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 internati

Colleagues,
My (formerly) preferred vendor of Intel based personal computer systems,
used for CISPR-11/22 and immunity testing of our boards and peripherals,
are lately having emissions up to the Class A limit fresh out of the box -
without any peripherals attached. So I must query the List Membe
