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?
