Good morning to all...

I have gone through what feels like every page of the ASHRAE Handbook of
Fundamentals in search of "N=20" and N=50" extreme high temperature
data. I was told it was in the Handbook, but I cannot find it and I
have spent the better part of two hours looking for it. Numerous web
searches have not yielded any results either. If anyone is willing to
help with this, I would very much appreciate it. The job is for a data
center, and they need the N=20 (described as a twenty year high
temperature) and the N=50 (described as a fifty year high temperature)
for design.

Any ideas? Anybody?

Thanks!
