Thanks Jim. To the most part that’s how I interpret it as well. Power and
telephone utilities have their own set of rules the get to play by, but
excluding equipment in an industrial plant seems odd. There was at least one
interpretation that B only applies to test equipment for the three catego
Gary, my understanding is section B applies to electric utilities only, or
electric utility hardware. In some cases a company might have their own
electric generation capability so it would apply to that equipment as
well. It does not apply to generic industrial equipment.

Doug,
Sounds like there is a piece of the puzzle missing.
For instance, the EN 61326-1 calls out Surge Immunity according to IEC61000-4-5
Level 3. The IEC 61000-4-5 calls out Level 3 to be 2KV. So unless your first
standard calls out the Basic standard then you would not know what “Level 3 “
John,
It does, but it fails to indicate which standard the severity levels are based
upon. Otherwise I wouldn’t be asking this question.

Hi Douglas,
Each of the Basic Standards from the series EN 61000-4-x ( esp -3,-4,-5, and
-6) have
their own list of test levels recommended to the committees writing the product
standard.
In general they are 1,2,3 and X.
Your product standard should not have referred to the test level number but
PS: Does not “your” standard have a list of all the referenced standards to
which you need to refer, as that might answer your question?

I think we do need to know the standard in question, and the edition, as the
pass/fail criteria for each of the Levels 1, 2 & 3 can vary from standard to
standard.

Fellow listers,
I recently ran into the following text in an EN standard:
“...unit should be tolerable for EMC severity level 3…”
I am trying to track down which IEC standard in the IEC 61000 series defines
EMC severity levels. If you know which standard this is please let me know.
