非破坏性检测 超声波相控阵设备的特性和验证 第3部分：完整系统（ISO 18563-3:2024）

[中文适用范围]： 该文件涉及实施阵列探头的超声波检测系统，适用于接触法（带楔块或不带楔块）或浸没法，中心频率范围为0.5 MHz至10 MHz。该文件提供了确定整个系统符合性的方法和验收标准（见3.2）。其目的是在测试前验证系统的正确运行或验证系统的退化情况不存在。这些方法并非旨在证明系统适用于特定应用的适用性，而是旨在证明整个系统（用于某一应用）根据所用设置正确运行的能力。测试可以针对单个超声波束进行（对于相控阵技术，请参见9.4.4），或者针对生成的图像进行（对于相控阵技术和全聚焦方法，请参见9.4.3）。测试可以仅限于特定应用打算使用的功能。该文件不涉及针对特定应用设置系统的灵敏度。它也不适用于机械扫描设备的表征或验证。这些项将在测试程序中涵盖。该文件未涉及使用串联技术的相控阵技术。对于死元素情况下的波束表征，或者需要更深入地了解波束的技术建议，在附录A中给出。它不适用于使用阵列的信号处理技术。 [外文原描述]： This document addresses ultrasonic test systems implementing array probes, for contact technique (with or without wedge) or for immersion technique, with centre frequencies in the range of 0,5 MHz to 10 MHz. This document provides methods and acceptance criteria for determining the compliance of the complete system (see 3.2). Its purpose is for the verification of the correct operation of the system prior to testing or verification of the absence of degradation of the system. The methods are not intended to prove the suitability of the system for particular applications but are intended to prove the capability of the complete system (used for an application) to operate correctly according to the settings used. Tests can be performed on individual ultrasonic beams (for phased array technique, see 9.4.4) or on resulting images (for phased array technique and total focusing technique, see 9.4.3). The tests can be limited to the functions that are intended to be used for a certain application. This document does not cover the sensitivity setting of the system for a specific application. Nor does it apply to the characterization or verification of the mechanical scanning equipment. It is intended that these items will be covered by the test procedure. This document does not address the phased array technique using tandem technique. The characterization of beams, as recommended in case of dead elements or for more in-depth knowledge of the beams, is presented in Annex A. It is not applicable for signal processing technology using arrays. NOTE Unless stated otherwise, in this document ‘TFM’ and ‘TFM technique’ refer to the total focusing technique as defined in ISO 23243, and to related techniques, see for example ISO 23865 and ISO 23234.
