Re: Sensitivity in Rt
In Reply to NGM at 10:13 Mar-22-2010 (Opening).

EN1435 and DNV cn7 provide double wall IQI tables. For a given penetrated thickness, the wire given in the table shall be visible.

Sensitivity calculation not provided. Therefore, it is not required to calculate sensitivity. The radiographs are acceptable provided the designated wire for a given technique is visible.
