John, You need to address your question to the committee that is
responsible for the standard you are questioning.
Remember that the standards writing business is a BOGSAT
process (Bunch Of Guys Sitting Around a Table). Most of the participants
are there because they know something about the subject (subject expert
matter delegates) or they have some issue that they either want addressed or
want to have it excluded from the standard (latter is usually not disclosed
until deep into the discussion). If the leader can come up with a
comprehensive outline as to the subjects to be addressed then the process
will be more comprehensive; if not it will be less organized.
Specifically for this case; why did the committee write
another standard that seems to cover the same ground as a base standard IEC
61000-4-2? Wot's the rationale for this additional standard?
Standards writing is not a scientific endeavor (even tho it
uses scientific principles, such as you pointed out); It's like sausage
making - but don't go into the kitchen if you aren't ready to be involved in
making the sausage.
If you have strong feelings about the completeness of the
product level standard perhaps you should be on the committee and straighten
it out. Don't just grumble, get involved.

Entropy ain't what it used to be

Subject: [PSES] Climatic conditions for ESD testing
IEC 61000-4-2 specifies climatic conditions for air discharge, including
barometric pressure. ISO 10605 (ESD for road vehicles) is silent about
barometric pressure.
As I remember, air pressure influences the reproducibility of air
discharges, which I assume is why IEC 61000-4-2 specifies limit on it. (ISO
10605:2008 even says this in Annex E.)
So, if it's important, why is this not specified in ISO 10605?
