Fabian,

I have same concern about standards referring to in-service inspection specifically corrosion mapping, I searched for that but it was not successful. API is developing a recommended practice (API RP 586) which is about application of advanced NDT methods of in-service inspection, but unfortunately is not released yet.

Accuracy of C-SCAN corrosion mapping directly depends on PA probe frequency, other factors such as surface condition, painting etc also can affect this.
Using a 5 MHz PA probe in normal condition, an accuracy of less than 1 mm is easily achievable.
Hope it helps
Arman
