TS EN ISO 23243

TS EN ISO 23243 is a vocabulary standard that collects and defines terms used in ultrasonic non-destructive testing with array technology. It provides a common technical language for phased array concepts, helping users describe the equipment, the inspection approach, and the interpretation context with consistent terminology.

Why terminology matters in phased array ultrasonic testing

In general technical terms, an ultrasonic array uses multiple elements that can be activated individually or in combination to steer, focus, and scan the sound beam. This makes it possible to inspect components with greater flexibility than a single-element probe, especially when searching for discontinuities such as cracks, lack of fusion, delaminations, or porosity. Concepts such as element pitch, steering angle, focal depth, and scan mode are central to how the inspection is planned and how the results are understood.

What this standard covers and what it does not

The document specifically defines terms related to phased arrays used in ultrasonic NDT. Its note states that the general terms used in ultrasonic non-destructive testing are defined in EN ISO 5577, so TS EN ISO 23243 complements the broader ultrasonic vocabulary rather than repeating it. As a vocabulary standard, it supports consistent language in technical reports, training materials, equipment documentation, and method descriptions.

In practice, that means the standard is focused on terminology consistency rather than inspection procedure details. It gives users a reliable shared vocabulary for discussing ultrasonic phased array systems and the distinct functions of their main concepts.
