scope:

This document covers linear phased array probes used for ultrasonic non-destructive examination in contact (with or without a wedge) or in immersion, with centre frequencies in the range 0,5 MHz - 10 MHz. This document specifies the characterisation tests that have to be done at the end of the fabrication of a phased array probe. It defines both methodology and acceptance criteria. It should be noted that these acceptance criteria are only valid under the conditions defined for the considered probe. This document does not describe methods and acceptance criteria to characterise the performance of a complete ultrasonic phased array system.
