This European Standard covers probes used for ultrasonic non-destructive examination in the following categories with centre frequencies in the range 0,5 MHz to 15 MHz, focusing and without focusing means:a) single or dual transducer contact probes generating compressional or shear waves;b) single transducer immersion probes.Where material-dependent ultrasonic values are specified in this document they are based on steels having a sound velocity of (5 920 ± 50) m/s for longitudinal waves, and (3 255 ± 30) m/s for transverse waves.Periodic tests for probes are not included in this document. Routine tests for the verification of probes using on-site methods
