2)

DI Distorted indication a possible tube wall loss condition that is unquantifiable with a numeric percent call due to the existing signal characteristics.

3)

INF Indication Not Found indicates that a previously reported Indication, from current inspection data or historical data, is not found in the data being analyzed - also used to address the case where a tube /

signal is being retested for positive' identification (PID) and the retest data does not show any signal present.

4)

INR Indication Not Reportable - indicates that a-very small tube wall loss condition exists in the data being analyzed that is below tha reportable criteria l
