Non-destructive testing — Characterization and verification of ultrasonic phased array equipment — Part 2: Array probes
This document specifies characterization tests to be performed at the end of the fabrication of an array probe. It defines both methodology and acceptance criteria.
This document is applicable to the following array probes used for ultrasonic non-destructive testing [phased array technique or signal processing technique, e.g. full-matrix capture (FMC) and total-focusing technique (TFM)] in contact technique (with or without a wedge or delay line) or in immersion technique, with centre frequencies in the range 0,5 MHz to 10 MHz:
a) array probes with elements in one direction:
— 1-D-linear array (linear array);
— 1-D-curved array;
— annular array;
b) array probes with elements in two directions:
— 2-D-array (matrix array);
— sectorial annular array;
— partial sectorial annular array.
This document does not give methods and acceptance criteria to characterize the performance of an ultrasonic phased array instrument or the performance of a complete system, which are given in ISO 18563–1 and in ISO 18563–3.
