GB/T 42399.3-2023 (Non-destructive testing instruments - Characterization and verification of ultrasonic phased array equipment - Part 3: Combined system) is available as an English-translated PDF.

GB/T 42399.3-2023 is the Chinese standard "Non-destructive testing instruments - Characterization and verification of ultrasonic phased array equipment - Part 3: Combined system".

Its scope clause reads: This document describes the inspection methods and acceptance criteria for the inspection of combined equipment (ie instruments, probes and connecting cables).

This document is applicable to contact type (with or without wedges) or liquid immersion linear array phased array probes with a center frequency of 0.5MHz~10MHz.

Ultrasonic testing system. This detection method is applicable to users in the field or workshop environment. Its purpose is to verify that the system is working correctly, Beam characteristics or check for system performance degradation.

This test method is not intended to prove the suitability of the system for a particular application, but to Demonstrate the ability of the combined device to generate an ultrasonic sound beam according to the setup.

The scope of this document does not include application-specific device calibration, which is generally covered by the testing process.

This document does not contain the following. --- Ring array; ---Aperture sequences with different numbers of array elements; --- The settings of transmission and reception are different (such as excitation aperture, effective number of array elements, delay); ---Adopt a single-array unit signal post-processing technology that is more complex than the simple delay rule (for example. full matrix acquisition). Its clauses include terms and definitions.

This document is applicable to contact type (with or without wedges) or liquid immersion linear array phased array probes with a center frequency of 0.5MHz~10MHz.

Ultrasonic testing system. This detection method is applicable to users in the field or workshop environment. Its purpose is to verify that the system is working correctly,

Beam characteristics or check for system performance degradation. This test method is not intended to prove the suitability of the system for a particular application, but to

Demonstrate the ability of the combined device to generate an ultrasonic sound beam according to the setup.

The scope of this document does not include application-specific device calibration, which is generally covered by the testing process.

This document does not contain the following.

--- Ring array;

---Aperture sequences with different numbers of array elements;

--- The settings of transmission and reception are different (such as excitation aperture, effective number of array elements, delay);

---Adopt a single-array unit signal post-processing technology that is more complex than the simple delay rule (for example. full matrix acquisition).
