Answer:
This is a tough question since there's a lot of disagreement out there about what defines a "standard" (which is often understood as meaning "best" or "optimal").
Better to list some common KPIs which I've seen employed by a number of pharma companies in different countries (and from a corporate/multinational perspective). Also, there are macro-level indicators that account for results across the entire SF, and micro-level indicators for results that can be used to benchmark individual sales performance. A few examples:
Macro:
Product Sales (value & volume)
Market Sales (value & volume)
Market Coverage
Market share
Market share growth
Micro (SFE):
Territory Occupancy Rate
Product Details (visits)
Customer Segmentation
On Target Interactions
Target Customer Coverage
Target Customer Visit Frequency
Days in the Field (activity type ratio)
Coaching days (double visits)
Message Delivery / message recall
% sales target achieved vs. % budget spent
