TS EN 1330-9

TS EN 1330-9 is a terminology standard for non-destructive testing that standardizes the terms used in acoustic emission testing. Acoustic emission testing is based on monitoring transient elastic waves released by activity such as cracking, plastic deformation, or other changes within a material or structure; this standard focuses on the common language of the method rather than the inspection procedure itself.

What the acoustic emission vocabulary covers

The standard covers only terms specific to acoustic emission testing and groups them into four main areas: terms relating to the physical phenomenon, terms relating to the detection of acoustic emission, terms relating to the measured acoustic emission signal or signals, and terms relating to acoustic emission applications. This structure helps prevent the same concept from being used inconsistently in different contexts and supports clearer interpretation of inspection results.

Technical context and practical relevance

Acoustic emission testing is used in many engineering settings, including welded assemblies, pressure equipment, storage tanks, composite structures and similar systems, to monitor events that may indicate damage initiation or growth. Terminology standards provide a shared framework for engineers, laboratories and inspection personnel, especially where sensors, signal processing, event definitions and application conditions need to be described consistently. Rather than prescribing how to perform the test, this document is dedicated to harmonising the terms used in the field.
