适用范围:This European Standard covers probes used for ultrasonic non-destructive examination in the following categories withcentre 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 soundvelocity 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-sitemethods are given in EN 12668-3.If parameters in addition to those specified in EN 12668-3 are to be verified during the probe's life time, as agreed uponby the contracting parties, the methods of verification for these additional parameters should be selected from thosegiven in this document.
