Minimum values of insulation resistance

Wombat
What is the science behind the 1 MOhm minimum insulation resistance? What is the basis for this particular value?

    It’s late and I haven’t done the calculation for a long time, 


    1/Rt = 1/R1 + 1/R2 and so on


    So the global insulation test result for the whole board is always less than the test result of the lowest reading circuit.


    Therefore each circuit can pass an insulation test, but the whole board can fail, so what do you do next?
