Dear John,
Thanks a lot for you clear answer.
We’ll try to combine an accelerated storage condition (with reference real-time at 35 °C) with an extended real-time 50% longer to see if they will accept our “worst case” proposed conditions.
p.s. RH is ruled out since packaging is non-porous and systems within are completely dry
Thanks for your support again, waiting for other opinions.
