Do demand factors apply to stand alone cook tops like in the link or only when combined with an oven sharing the same circuit?

Are you thinking of Article 220 calculations? This is from T220.55.

Table 220.55 Demand Factors and Loads for Household Electric Ranges, Wall-Mounted Ovens, Counter-Mounted Cooking
Units, and Other Household Cooking Appliances over 1 3 ? 4 kW Rating (Column C to be used in all cases except as otherwise
permitted in Note 3.)
