本文件规定了用于无损超声检测的探头的特性，这些探头的中心频率在0.5兆赫至15兆赫之间，有聚焦装置也有无聚焦装置: a） 产生纵向的单探头或双探头接触探头 和/或横波； b） 单探头浸入式探头。 如果本文件中规定了与材料相关的超声波值，则这些超声波值基于声速为（5920±50）m/s（纵波）和（3255±30）m/s（横波）m/s的钢材。 本文件 不包括探头的定期试验。ISO 22232-3中给出了使用现场程序验证探头的常规试验。 如果除ISO 22232-3中规定的参数外，还需按照缔约方的约定，在探头的使用寿命期间进行验证， 这些附加参数的验证程序可从本文件中给出的程序中选择。 本文件也不包括超声相控阵探头，因此见ISO 18563-2。

This document specifies the characteristics of probes used for non-destructive ultrasonic testing in the following categories with centre frequencies in the range of 0,5 MHz to 15 MHz, focusing or without focusing means: a) single- or dual-transducer contact probes generating longitudinal and/or transverse 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. This document excludes periodic tests for probes. Routine tests for the verification of probes using on-site procedures are given in ISO 22232-3. If parameters in addition to those specified in ISO 22232-3 are to be verified during the probe's life time, as agreed upon by the contracting parties, the procedures of verification for these additional parameters can be selected from those given in this document. This document also excludes ultrasonic phased array probes, therefore see ISO 18563-2.
