本文件规定了通过使用适当的标准校准块验证组合超声检测设备（即仪器、探头和连接电缆）性能的方法、公差和验收标准。 这些方法专门用于手动测试设备，即符合ISO 22232-1的超声波仪器，以及符合ISO 22232-2的单探头或双探头手动超声波无损检测。本文件也适用于多通道仪器。对于自动化测试设备，可能需要进行不同的测试以确保令人满意的性能。 指定方法适用于在现场或车间条件下工作的操作员。 这些方法不旨在证明设备适用于特定应用。 本文件不包括用于连续波的超声波仪器。 本文件也不包括超声波相控阵系统，参见ISO 18563-3。如果相控阵仪器与单探头或双探头组合使用，本文件适用于这种组合。

This document specifies methods, tolerances and acceptance criteria for verifying the performance of combined ultrasonic test equipment (i.e. instrument, probes and cables connected) by the use of appropriate standard calibration blocks. These methods are specifically intended for manual test equipment, i.e. ultrasonic instruments according to ISO 22232-1, and for manual ultrasonic non-destructive testing with single- or dual-transducer probes according to ISO 22232-2. This document is also applicable for multi-channel instruments. For automated test equipment, different tests can be needed to ensure satisfactory performance. The specified methods are intended for the use by operators working under site or shop floor conditions. These methods are not intended to prove the suitability of the equipment for particular applications. This document excludes ultrasonic instruments for continuous waves. This document also excludes ultrasonic phased array systems, see e. g. ISO 18563-3. If a phased array instrument is used in combination with single- or dual-transducer probes, this document is applicable to this combination.
