Hi Dave,
We only usually specify the requirement of conformal coating for reduced intrinsic safety creepages and clearances.

Subject: [DC] DFH : Design for Humidty
Anyone have experience determining when an Electronic Assembly requires added precaution against humidty ?
Are there any specifications which outline when an assembly must be conformal coated / potted / moisture sealed ?
I've designed many PCBs over the years for various Military and Automotive applications where specific environmental protection was required but this was always laid out in reference to a specific standard on the statement of work. In this case I simply have a requirement that the assembly remain functional at a certain humidty level.
