IATA defines "Conditions Normal to Air transport" as -40 C and 55 C which somehow they convert to -40F and 130 F Your packagings in your warehouse should be designed to withstand these extremes if they are ever on an airplane. I suspect DOT has similar specifications but I am not sure what they are.

Does anyone have a further definition of cool and dry that they use in practice? I am struggling with storage issues in open air warehouse locations throughout the US. Dallas came up this morning.
