TS EN 1330-4

TS EN 1330-4 is a terminology standard for non-destructive testing that collects the terms and definitions used in ultrasonic testing. Its purpose is to establish a common technical language for ultrasonic inspection, helping engineers, operators, and quality personnel use the same concepts consistently in reporting, training, and documentation. The subject of this standard is the vocabulary of the method, not the test procedure itself.

How terminology supports ultrasonic testing

Ultrasonic testing relies on the propagation, reflection, and scattering of high-frequency sound waves in a material. In practice, concepts such as probe, couplant, signal, echo, backwall response, and flaw indication are central to interpreting results. A terminology standard clarifies the boundaries of these concepts and reduces ambiguity in technical communication. In general technical use, precise terminology improves comparability of inspection results, consistency of records, and clarity of engineering documentation.

What this document covers

• Terms used in ultrasonic testing
• Common technical language within non-destructive testing terminology
• Support for training, documentation, and reporting consistency

This record is based on EN 1330-4 and is now withdrawn. It should therefore be treated as an archival technical reference, while still being useful for understanding the core vocabulary of ultrasonic testing. Its value lies in organizing the language of the field, rather than prescribing a specific inspection procedure.
