Most SOPs and FOMs give one plenty of rope, and will even show you how to knot it.

"When the aircraft's critical surfaces are not free of frozen contaminants, or it cannot be determined that they are free from contaminants, the PIC notifies the station that ground deicing is required"

The paragraph immediately preceding the above paragraph suggests using the jetbridge or terminal to determine that "ALL" surfaces are free and clear of contaminants.
This info was gleaned from the SOP, Ground Deicing Program and FOM.

In essence to satisfy the requirements for our airline, during active icing precip, it would almost be impossible to achieve. Add variable intensities and you are rolling the dice.
