Characterization and verification of air-coupled ultrasonic probes

September 2022

Kategorie: DGZfP-Regelwerke, engl.

This guideline was drafted following and complementing the norm ISO 22232-2:2020(E) to include air-coupled ultrasonic transducers.

This document specifies the characteristics of probes used for non-destructive air-coupled ultrasonic testing with center frequencies above 20 kHz, with focusing or without focusing means. This document refers to probes based on the piezoelectric effect. Air-coupled probes based on other physical principles may be characterized according to this guideline if it is judged as appropriate.

This document excludes periodic tests for probes. Routine tests for the verification of contact probes using on-site procedures are given in ISO 22232-3. These may also be applied to air-coupled probes.
