Jason,
As a General Rule, all aviation measures are taken
against a "Standard Day." FAR part 1 should have the definition, but if
yours does not:
* Humidity = 50%
* Altitude = Mean Sea Level
* Altimeter setting = 29.92
* Temperature = 59 degrees F.
* Winds = none.
I can see where air density could change static RPM,
perhaps adjusting it to in or out of limits. Whether this is
Eliacim's case, I don't know.

I haven't looked it up, but would wonder if these limits
are valid for "standard" conditions of if the range given is to help take into
account for this?

Eliacim,
Couple of
considerations:
- Static rpm is what you get on the
ground with full power in a zero wind condition. (On a windy day, I’ve
approximated no-wind condition by turning the propeller plane sideways to the
wind. It’s not exactly the same as no-wind conditions but it’s much
closer than having your nose into the wind. Don’t overheat the
engine.)
