I found an interesting old document “CISPR Report of the Plenary
Session held in The Hague from 18^th to 21^st November 1958”.
It mentions a Study Question 18 (Brussels 1956): “what method should
be used when applying limits for radio interference to appliances in
large-scale production?”
I could not find anything more on this, but it looks like a kick-off
for the statistical evaluation.
And no, I was not there.

I know it is in VDE 0871/6.78, so it dates back to at least June of
1978. I don’t know about anything prior to that. VDE 0871/6.78 is
also the only place I’ve seen a requirement that if a single unit is
tested then a 2 dB margin is required.

I agree: I'm almost certain that it is German in origin, and I'm sure
it dates back to the 20th Century, possibly as early as 1960.

If my memory serves me right, as I recall, the 80/80 rule was in
at least one of the VDE standards regarding radiated emissions. I
can’t recall the number or name. This is going back to the late
‘70s or so.

Can someone tell me when the 80/80 rule was introduced into
CISPR standards and if possible, a bit more detail than just
the date, please?
