Is it not possible to refer such a divergence to TC108 for a ruling on
interpretation? Maybe even an Interpretation Sheet would be generated if
the 'ES2' test house has misunderstood the standard.

Hi Boštjan:
If you say ES1 and another certification body says ES2, then a
negotiation must take place.
To avoid negotiation, you must change your verdict to ES2.
However, the manufacturer wants ES1, which is determined by the
voltage. I agree that the voltage waveform is ES1 value, and the
current is not. But only one parameter, voltage or current, is needed
to determine ES1.
Good luck, and best regards,
Rich

Hi Pete,
What manufacturer is expecting is the exact answer. Does this output
complies with ES1 or it is ES2? And of course justification for this
decision. If I accept it as ES1 and then later the other certification
body says it is ES2 it is a big problem for the manufacturer.
If you see below my understanding how can we interpret the standard
then separation to AC and DC part for the single pulse is not required
and limit is always 60Vpk. Do you agree?
There is no limitation for maximum duration of the single pulse in the
standard. Also pulse off time is not clear (is it time when pulse
voltage is at zero or the time when pulse voltage is below certain
voltage).
I know that as a member of HBSDT and OSM I have tools in my hands
however I do not see a quick solution. So some experiences and
opinions from members of this group are appreciated.
The question that was previously raised at TC was a bit different, it
was not a pulsing waveform.
Best regards,
Bostjan
