UNE-EN ISO 18563-2:2025

This document specifies the characterization tests 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. FMC-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 combined system. These are given in

ISO 18563 1 and in ISO 18563 3.
