Do any product standards actually set limits for immunity to supply

One that comes to mind (specific to Programmable Controllers [ aka PLC's])
is EN 61131-2 (IEC 61131-2).

1. A place to put the test equipment.
2. All the little associated goodies, like cables probes connectors
the usual forgotten items.
3. Cost of maintenance and periodic calibration.
4. Somebody to learn how

Hi Joe,
Not sure I've understood your question correctly. Are you asking
1) If there are further tests that need to be added to your list to complete
the EMC requirements (excluding of course radiated emissions and immunity)
or
2) What extra equipment you need to perform the tests you
Keep in mind that some of these tests call for a rather specific table and
floor with grounded planes and very specific distances. When I've seen this
done properly, it was an extensive (and possibly expensive) job. Look
carefully at the EN documents, particularly the appendices which typically
