Measuring Insulation Resistance

When we measure insulation resistance of wiring, cables, motors, transformers, alternators etc. what is the standard reference temperature?. If we measure at a different temperature is there a table/chart to convert to a standard reference temperature(say,20 deg C)?

I'm a little bogged down at the moment to answer in too much depth.

The following online publication describes how to adjust for temperature:


There is also a rule of thumb for rotating machines that says "insulation resistance halves for 10 oC increase in temperature.
